# roro9stack
|
||||
|
||||
A multi-app handheld operating environment for the M5Stack Cardputer ADV with the Cap LoRa-1262, whose first job is to be a Meshtastic-compatible mesh messenger.
|
||||
|
||||
## Language
|
||||
|
||||
**App**:
|
||||
A foreground, user-facing program chosen from the Launcher. Only one App is on screen at a time; Apps show and act on what Services hold.
|
||||
_Avoid_: program, tool, screen
|
||||
|
||||
**Launcher**:
|
||||
The App that lists every other App and starts them. It's the home screen.
|
||||
_Avoid_: menu, home
|
||||
|
||||
**Service**:
|
||||
A long-lived background capability that keeps running whichever App is in the foreground (e.g. Mesh Service, GNSS Service).
|
||||
_Avoid_: daemon, task, driver
|
||||
|
||||
**Mesh Service**:
|
||||
The Service that keeps the device participating in a mesh network at all times: receiving, relaying, and sending on behalf of Apps.
|
||||
_Avoid_: radio, LoRa app
|
||||
|
||||
**Radio Service**:
|
||||
The Service that owns the LoRa radio on the Cap: it configures it, shares the SPI bus with the SD card, and receives in the background. The LoRa Scanner uses it directly; the Mesh Service sits on top of it.
|
||||
_Avoid_: LoRa driver, modem
|
||||
|
||||
**Mesh Protocol**:
|
||||
One on-air language the Mesh Service can speak (Meshtastic first; others may follow). The Mesh Service speaks Mesh Protocols; Apps don't.
|
||||
_Avoid_: stack, mode
|
||||
|
||||
**Node**:
|
||||
Any device participating in the mesh, including this one. It's identified by a node number and has a long and a short name.
|
||||
_Avoid_: peer, device, station
|
||||
|
||||
**Channel**:
|
||||
A named mesh conversation space defined by a name and a shared key. Every Node on the same Channel can read its traffic.
|
||||
_Avoid_: group, room
|
||||
|
||||
**Direct Message**:
|
||||
A text message addressed to a single Node instead of a Channel.
|
||||
_Avoid_: DM (in docs), private message
|
||||
|
||||
**Relaying**:
|
||||
Rebroadcasting another Node's packet so it travels further across the mesh.
|
||||
_Avoid_: forwarding, repeating
|
||||
|
||||
**Capsule**:
|
||||
A Gemini site: everything served by one host on Geminispace.
|
||||
_Avoid_: site, server (when the content is meant)
|
||||
|
||||
**Saved Page**:
|
||||
A Gemini page kept on the SD card to read offline, with the URL it came from and when it was saved. Kept until the user deletes it; Storage Clean-up never offers it.
|
||||
_Avoid_: cache, download (a download is a non-text file saved from Gemini)
|
||||
|
||||
**GNSS Service**:
|
||||
The Service that owns the GNSS receiver on the Cap: it reads its NMEA sentences in the background and holds the current Fix, position, time and satellites.
|
||||
_Avoid_: GPS (GPS is one constellation among several)
|
||||
|
||||
**Fix**:
|
||||
What the receiver currently knows: none, 2D (position without altitude) or 3D (with altitude), from how many satellites, at what HDOP.
|
||||
_Avoid_: lock, signal
|
||||
|
||||
**Track**:
|
||||
A route recorded from GNSS positions to a GPX file on the SD card, started and stopped by the user.
|
||||
_Avoid_: trace, log (a Log is recorded on its own)
|
||||
|
||||
**Wi-Fi Service**:
|
||||
The Service that owns the Wi-Fi radio. It's always in exactly one mode: *Off*, *Connected* (joined to a Saved Network) or *Monitoring* (passively observing). When Wi-Fi is enabled in Settings, it stays Connected whenever a Saved Network is in range. It goes Monitoring only while Wi-Fi Tools needs it, then reconnects.
|
||||
_Avoid_: network manager
|
||||
|
||||
**Saved Network**:
|
||||
A Wi-Fi network the device may join on its own (name, password). When several are in range, the strongest wins.
|
||||
_Avoid_: profile, known network
|
||||
|
||||
**IRC Service**:
|
||||
The Service that keeps the IRC connection alive in the background once the IRC App has started it, until the user stops it (`/quit`, or `irc stop` on the console). Once stopped by hand, opening the App again doesn't reconnect; typing a line does. It reconnects after drops, and pauses while the Wi-Fi Service is Monitoring. It does not start by itself after a reboot.
|
||||
_Avoid_: IRC client (that's the App)
|
||||
|
||||
**Buffer**:
|
||||
One IRC conversation shown in the IRC App: the server, a channel, or a private chat with one nick. Each Buffer counts its unread messages.
|
||||
_Avoid_: window, tab, room
|
||||
|
||||
**Mention**:
|
||||
An IRC message containing the user's nick, or any private message. Mentions raise Notifications; other traffic only counts as unread.
|
||||
_Avoid_: highlight, ping
|
||||
|
||||
**Status Bar**:
|
||||
The strip shown on every screen with system state at a glance: battery, GNSS fix, mesh activity, Wi-Fi mode and unread count.
|
||||
_Avoid_: header, top bar
|
||||
|
||||
**Notification**:
|
||||
News from a Service that reaches the user while another App is in the foreground. It shows as a brief Toast and may beep or flash.
|
||||
_Avoid_: alert, popup
|
||||
|
||||
**Sniffer**:
|
||||
The LoRa Scanner mode that passively listens with the Mesh Service's own radio settings. It never interrupts mesh participation.
|
||||
_Avoid_: monitor (that word belongs to Wi-Fi)
|
||||
|
||||
**Sweep**:
|
||||
The LoRa Scanner mode that takes over the radio to survey frequencies. It pauses the Mesh Service while active.
|
||||
_Avoid_: scan (ambiguous with Wi-Fi scanning)
|
||||
|
||||
**Region**:
|
||||
The regulatory band plan the device transmits under (here EU868). It sets the allowed frequencies, power and duty cycle. Nothing transmits until it has been confirmed.
|
||||
|
||||
**Duty Cycle Budget**:
|
||||
The share of airtime the Region allows this device to transmit. When it's used up, outgoing traffic waits.
|
||||
|
||||
**Text Entry**:
|
||||
When an App is editing text. During Text Entry, `;` `.` `,` `/` type their characters and Fn makes them arrows. Otherwise they are arrows on their own.
|
||||
_Avoid_: edit mode, insert mode
|
||||
|
||||
**Compose Key**:
|
||||
The `opt` key used as a dead key. Pressing it and then a base letter types an accented character (e.g. `opt` `'` `e` → é).
|
||||
_Avoid_: modifier, alt
|
||||
|
||||
**Log**:
|
||||
History the device records automatically in the background: mesh message history, IRC logs, Wi-Fi scan logs.
|
||||
_Avoid_: history file, dump
|
||||
|
||||
**Capture**:
|
||||
Data the user explicitly starts recording, such as Wi-Fi packet captures and LoRa Sniffer captures.
|
||||
_Avoid_: dump, log
|
||||
|
||||
**Storage Warning**:
|
||||
The Notification raised once per boot when the SD card passes 80% full. Selecting it opens Storage Clean-up.
|
||||
|
||||
**Storage Clean-up**:
|
||||
The screen where the user deletes old Logs and Captures by category and age, with a preview of the space freed. Notes are never offered for deletion.
|
||||
|
||||
**Firmware Update**:
|
||||
Installing a new firmware image without a USB cable: pushed over Wi-Fi from the developer's PC, or read from the SD card.
|
||||
_Avoid_: flash, upgrade (alone)
|
||||
|
||||
**Update File**:
|
||||
One signed file (`.ota`) that carries a firmware version, its image and a signature. The same file works over Wi-Fi and from the SD card. Anything not signed with the project's key is refused.
|
||||
_Avoid_: binary, bin
|
||||
|
||||
**Probation**:
|
||||
The state of newly installed firmware until it proves healthy: booted, UI drawn, Services started, 30 s without a crash, and Wi-Fi connected if it's configured. Then it's confirmed for good.
|
||||
_Avoid_: trial, test mode
|
||||
|
||||
**Rollback**:
|
||||
Returning automatically to the previous firmware when new firmware resets or crashes during Probation.
|
||||
_Avoid_: revert, downgrade (a downgrade is installing an older version on purpose)
|
||||
|
||||
**Safe Mode**:
|
||||
What the firmware starts instead of everything else after 3 crash restarts in a row: Wi-Fi and Firmware Updates (and the Debug Console in a Debug Build), so it can be fixed without a cable. A normal restart leaves it.
|
||||
_Avoid_: recovery mode, failsafe
|
||||
|
||||
**Debug Build**:
|
||||
A firmware built with the remote debugging aids compiled in (`+debug` in its version). Release builds have none of them.
|
||||
_Avoid_: dev build, test build (a test build is one made to fail on purpose, such as a crashing update)
|
||||
|
||||
**Debug Console**:
|
||||
The console of a Debug Build over Wi-Fi: live log lines and the serial commands, behind a token.
|
||||
_Avoid_: telnet, remote shell
|
||||
|
||||
## Relationships
|
||||
|
||||
- The **Launcher** starts **Apps**. Exactly one **App** is in the foreground.
|
||||
- **Services** keep running underneath, regardless of which **App** is in the foreground.
|
||||
- The **Mesh Service** speaks one or more **Mesh Protocols** and tracks the known **Nodes**.
|
||||
- The **Wi-Fi Service** is either Connected or Monitoring, never both. Monitoring pauses the **IRC Service**, which reconnects and rejoins its **Buffers** afterwards.
|
||||
- **Services** raise **Notifications**; the **Status Bar** summarises **Service** state.
|
||||
- The **Radio Service** owns the radio; the **Mesh Service** and the LoRa Scanner use it.
|
||||
- A **Sweep** pauses the **Mesh Service**; a **Sniffer** does not.
|
||||
- Every transmission is bounded by the **Region** and its **Duty Cycle Budget**.
|
||||
- Past 90% SD usage, **Logs** stop being written; the remaining space is kept for **Captures**. Nothing is deleted without the user's confirmation.
|
||||
- A **Firmware Update** installs an **Update File**; the new firmware runs on **Probation**, and fails back by **Rollback**.
|
||||
- **Rollback** covers new firmware; **Safe Mode** covers confirmed firmware that keeps crashing.
|
||||
- A **Node** may be in several **Channels**. A **Direct Message** targets exactly one **Node**.
|
||||
|
||||
## Flagged ambiguities
|
||||
|
||||
- "LoRa" was used both for the radio and for the mesh. Resolved: say **Mesh Service** for the always-on participation and **Mesh Protocol** for the on-air format. The LoRa Scanner **App** uses the radio directly and doesn't speak a **Mesh Protocol**.
|
||||
- "Channel" has three meanings here. Resolved: an unqualified **Channel** is the mesh one. The others are always qualified as "IRC channel" (a kind of **Buffer**) and "Wi-Fi channel" (radio frequency, 1–13).

GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too, receive
|
||||
or can get the source code. And you must show them these terms so they
|
||||
know their rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software: you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation, either version 3 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program. If not, see <https://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
<program> Copyright (C) <year> <name of author>
|
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, your program's commands
|
||||
might be different; for a GUI interface, you would use an "about box".
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
||||
For more information on this, and how to apply and follow the GNU GPL, see
|
||||
<https://www.gnu.org/licenses/>.
|
||||
|
||||
The GNU General Public License does not permit incorporating your program
|
||||
into proprietary programs. If your program is a subroutine library, you
|
||||
may consider it more useful to permit linking proprietary applications with

# roro9stack
|
||||
|
||||
A multi-app firmware for the **M5Stack Cardputer ADV** with the **Cap LoRa-1262**. It's a Meshtastic-compatible mesh messenger, plus Wi-Fi tools, IRC, GNSS and more. Licensed GPL-3.0.
|
||||
|
||||
- Domain language: [CONTEXT.md](CONTEXT.md)
|
||||
- Decisions: [docs/adr/](docs/adr/)
|
||||
- Milestones: [docs/milestones/](docs/milestones/)
|
||||
|
||||
## Requirements
|
||||
|
||||
Only **Docker** is needed. PlatformIO and the ESP32 toolchain run inside a container, and are cached in the `roro9stack-pio` Docker volume. The first build downloads about 1 GB and takes a few minutes.
|
||||
|
||||
## Build and test (local CI)
|
||||
|
||||
```sh
|
||||
scripts/ci.sh
|
||||
```
|
||||
|
||||
This runs the host-side unit tests (`test/`, `native` environment), then builds the firmware. The output is `.pio/build/cardputer-adv/firmware.factory.bin`.
|
||||
|
||||
The framework is rebuilt with the TLS settings in `platformio.ini` (`custom_sdkconfig`, ADR 0006), so the first build after a fresh checkout takes about 4 minutes; later builds take under a minute.
|
||||
|
||||
## Flash
|
||||
|
||||
1. Connect the Cardputer by USB-C.
|
||||
2. Run:
|
||||
|
||||
```sh
|
||||
scripts/flash.sh # auto-detects the port; or: scripts/flash.sh /dev/ttyACM1
|
||||
```
|
||||
|
||||
This uploads the firmware, then opens the serial monitor. Quit the monitor with `Ctrl+C`.
|
||||
|
||||
**If the upload can't connect,** put the device in download mode: hold **G0** (the button next to the screen) while plugging in USB, or while pressing reset. Then retry.
|
||||
|
||||
**If you get "permission denied" on the port,** your user needs access to the serial device. Run this once, then log out and back in:
|
||||
|
||||
```sh
|
||||
sudo usermod -aG dialout "$USER"
|
||||
```
|
||||
|
||||
## Firmware Updates over Wi-Fi (OTA)
|
||||
|
||||
Once the Cardputer runs an OTA-capable firmware (flashed once over USB), updates can go over Wi-Fi:
|
||||
|
||||
```sh
|
||||
scripts/ota_keygen.sh # once: creates the signing key (see ADR 0003)
|
||||
scripts/flash.sh --ota 10.39.39.12 # build, sign and push; or set RORO_OTA_HOST
|
||||
```
|
||||
|
||||
The device shows the push address in **Settings → Firmware**. It installs a correctly signed update right away, restarts (waiting up to 60 s if you're typing), and runs the new firmware on **Probation**. If the new firmware crashes, or can't reconnect Wi-Fi within 3 minutes, it rolls back to the previous one and says so.
|
||||
|
||||
To install from the SD card instead, copy the `.ota` file from `.pio/build/cardputer-adv/` into `/updates` on the card, then use **Settings → Firmware**. With the Cardputer on USB, the card can stay in: `scripts/sd_put.sh <file.ota>` sends it over the serial console into `/updates` (about 30 s for 1.6 MB, checked with SHA-256 before it's renamed into place; `SD_PUT_DEBUG=1` shows the console while it runs).
|
||||
|
||||
**The private key** lives in `~/.config/roro9stack/ota-key.pem` and must never be committed. If it's lost, generate a new pair and flash once over USB.
|
||||
|
||||
## Gemini
|
||||
|
||||
The Gemini App browses Geminispace (docs/milestones/G1.md): Tab and Shift+Tab pick a link, Enter follows it, Back returns (to where the page was scrolled), Space pages down, `g` types an address. Certificates are trusted on first use; a changed one stops the page and asks.
|
||||
|
||||
On a page, `b` bookmarks it, `s` saves it to the SD card to read offline (a non-text file goes to `/gemini/downloads/`), `S` saves it with the pages it links to on the same capsule (up to 30). The start page lists bookmarks and Saved Pages; inside a Saved Page, `r` refreshes it and `d` deletes it. With a card, every page streams through `/gemini/cache/` so a large one arrives whole even with IRC connected; what doesn't fit in memory stays on the card.
|
||||
|
||||
## LoRa Scanner
|
||||
|
||||
The LoRa Scanner (docs/milestones/M3.md) listens with the Cap's radio and **never transmits**. The Sniffer lists what it hears, newest first: time, RSSI, SNR, and for Meshtastic packets the sender and receiver (their last 4 hex digits) and hops. Enter shows a packet's details: the Meshtastic header (which is never encrypted) and a hex dump. `p` picks one of the 7 Meshtastic presets allowed in EU868 (LongFast by default), `c` starts or stops a Capture: a pcap file with LoRaTap headers in `/captures/lora/`, for Wireshark. A Capture keeps recording with the App closed; otherwise the radio sleeps when the App isn't open. Tab switches to **Sweep**: the signal strength across 863–870 MHz in 100 kHz steps, as bars with peak hold and a waterfall, with the Sniffer's frequency marked; the Sniffer is paused meanwhile and picks up where it was. The Status Bar shows `L` while the radio listens (bright for a moment on each packet), `SW` while sweeping, and `CAP` while capturing.
|
||||
|
||||
## Development aids
|
||||
|
||||
`scripts/serial_log.sh [seconds] [command…]` records the serial output, and can send commands to the firmware first. For example, `scripts/serial_log.sh 30 short sleep:12 burst` sets short screen timeouts, waits 12 s, then sends a burst of Toasts.
|
||||
|
||||
| Command | Effect |
|
||||
|---|---|
|
||||
| `burst` | Publishes 5 Notifications at once |
|
||||
| `key up\|down\|left\|right\|select\|back\|home`, or `key <char>` | Injects a key press |
|
||||
| `sound on` / `sound off` | Toggles the Sound setting (beep + LED) |
|
||||
| `short` / `normal` | Screen timeouts 5 s / 10 s, or 30 s / 60 s |
|
||||
| `wifi add <ssid><TAB><password>` | Adds a Saved Network (so credentials stay out of the repo) |
|
||||
| `log <text>` | Appends a line to a test IRC Log (`/irc/dev/#test/<date>.log`) |
|
||||
| `sd card` | What the SD card says it is: type, size, and its identity register (maker, name, revision, serial, date) |
|
||||
| `sd list` | Lists the files of each Storage Clean-up category |
|
||||
| `cat <path>` | Prints the first ~1.2 KB of a file on the SD card |
|
||||
| `irc start` | Starts the IRC Service (normally done by opening the IRC App) |
|
||||
| `irc stop` | Stops it, as `/quit` does: QUIT if connected, no more retries, and the App stays disconnected until you type |
|
||||
| `gemini get <url>` | Fetches a Gemini page and prints its header, size, certificate fingerprint and heap use |
|
||||
| `gemini trust <host> <port> <sha256>` | Pins a certificate by hand (the Gemini App asks when one changes) |
|
||||
| `irc say <buffer> <text>` | Types into a Buffer, commands included (`irc say 0 /join #test`) |
|
||||
| `irc dump` | Prints IRC status, memory, and the last lines of each Buffer |
|
||||
| `wifi status` | Prints Wi-Fi state, network, signal, clock and free heap |
|
||||
| `info` | Firmware, uptime, last start reason, memory, Wi-Fi, the SD card and its write faults since boot, and both app slots with their versions and OTA states |
|
||||
| `tasks` | FreeRTOS tasks: state, priority, lowest free stack, CPU share |
|
||||
| `reboot` / `boot other` | Restart, or restart into the other app slot (a manual Rollback) |
|
||||
| `log level <0-5>` | ESP-IDF log level |
|
||||
| `ls [folder]` / `rm <path>` | Lists a folder of the SD card, or deletes a file |
|
||||
| `install <path>` | Update from SD with that `.ota` file, as Settings → Firmware does |
|
||||
| `lora probe` | Finds the radio: chip, oscillator, antenna switch, DIO1 interrupt, noise floor |
|
||||
| `lora status` | Radio settings, who's listening, packet and error counters, noise floor, task stack |
|
||||
| `lora rx on` / `lora rx off` | Listens and prints each packet on the console |
|
||||
| `lora preset <name>` / `lora custom <MHz> <BW kHz> <SF> <CR> <sync hex> [preamble]` | Receive settings: a Meshtastic preset, or anything else (`lora custom 868.1 125 7 5 34 8` for LoRaWAN) |
|
||||
| `lora capture start` / `lora capture stop` | A LoRa Capture, as `c` in the App |
|
||||
| `lora sweep on [from MHz] [to MHz] [step kHz]` / `lora sweep off` / `lora sweep dump` | Sweep a band (863 870 100 by default), with a summary every 2 s (floor, strongest, peaks), or print the latest pass |
|
||||
| `lora inject <hex> [rssi] [snr]` | Debug Builds: a packet into the Scanner as if received (nothing is sent) |
|
||||
| `crash` | The last crash: which firmware, why, task, PC and backtrace (from the core dump in flash) |
|
||||
| `coredump erase` | Forgets the core dump |
|
||||
| `crash abort` / `crash wdt` | Debug Builds: crash on purpose, or hang the main loop until the watchdog fires |
|
||||
| `help` | Lists the commands |
|
||||
|
||||
`scripts/flash.sh` stops a running serial log first, since it would hold the port.
|
||||
|
||||
### Debug Builds and the Debug Console
|
||||
|
||||
`scripts/flash.sh --debug` (USB) or `scripts/flash.sh --debug --ota <ip>` (Wi-Fi) installs a Debug Build: the same firmware plus the Debug Console on TCP 2323 (ADR 0004). Then, with `RORO_OTA_HOST` set to the device's IP:
|
||||
|
||||
```sh
|
||||
scripts/rdbg.py # interactive: the console backlog, live lines, and commands
|
||||
scripts/rdbg.py info # one command and its reply
|
||||
scripts/rdbg.py -b tasks # the same, after the backlog (boot messages and so on)
|
||||
```
|
||||
|
||||
Every command above works there too, plus a few handled by the PC side or the console's own task:
|
||||
|
||||
```sh
|
||||
scripts/rdbg.py crash # the last crash, its backtrace decoded against that exact build's ELF
|
||||
scripts/rdbg.py coredump # fetch the core dump and decode it all (registers, every task) with esp-coredump
|
||||
scripts/rdbg.py reset # restart at once, even if the main loop is stuck
|
||||
scripts/rdbg.py screenshot # the screen as a PNG (2x)
|
||||
scripts/rdbg.py put <file> [card path] # to the SD card (default /updates/<name>), SHA-256 checked, ~300 KB/s
|
||||
scripts/rdbg.py get <card path> [file] # from the SD card
|
||||
```
|
||||
|
||||
So a Firmware Update can also go `rdbg.py put roro9stack-….ota` then `rdbg.py install /updates/roro9stack-….ota`: the Update from SD path, without touching the device.
|
||||
|
||||
Every build keeps its ELF in `.pio/elves/` (version and digest in the name) for that; `scripts/decode_backtrace.sh <version|digest> <addresses>` decodes any backtrace by hand.
|
||||
|
||||
After 3 crash restarts in a row the firmware starts in **Safe Mode** (ADR 0005): only Wi-Fi, Firmware Updates and the Debug Console, so a fix can be pushed as usual. `reboot` leaves it. The token is in `~/.config/roro9stack/debug-token`, made by the first build; keep developing on Debug Builds, so the firmware a Rollback returns to always has the console.

# Own firmware that speaks Meshtastic, not a Meshtastic fork
|
||||
|
||||
We build our own firmware from existing libraries (PlatformIO + Arduino-ESP32, M5Cardputer/M5Unified, RadioLib, TinyGPSPlus, nanopb with Meshtastic's published protobufs). We implement the Meshtastic protocol ourselves as one pluggable Mesh Protocol, rather than forking the Meshtastic firmware, which already supports this exact hardware.
|
||||
|
||||
A fork would give full compatibility on day one, but its architecture is built around being a single-purpose Meshtastic node. That conflicts with our goals: a multi-app OS with a fully custom UX, and room for other mesh protocols (e.g. MeshCore) later.
|
||||
|
||||
## Consequences
|
||||
|
||||
- We accept partial Meshtastic compatibility at first: text on channels, Direct Messages, node list, position and relaying.
|
||||
- The phone-app (BLE) API and PKI-encrypted Direct Messages are deferred, and we must re-implement protocol details ourselves.
|
||||
- Multi-boot with stock Meshtastic via a launcher was rejected: it gives none of our own UX.
|
||||
|
||||
## Note (2026-10-04, M2)
|
||||
|
||||
NMEA is parsed by our own small, host-tested parser instead of TinyGPSPlus: the GNSS App's Sky view needs the satellite list (GSV) across several constellations, which TinyGPSPlus doesn't track. See docs/milestones/M2.md, Q66.

# Own small widget kit on M5GFX, not LVGL
|
||||
|
||||
The UI is drawn with M5GFX into an off-screen buffer, using a small widget kit we own: list, text view, line editor, dialog, Status Bar and Toast. We chose this over LVGL.
|
||||
|
||||
LVGL would give us ready-made widgets, but it costs roughly 40–60 KB of RAM on a device with no PSRAM. It would also need to coexist with the Mesh Service, the Wi-Fi stack and TLS, and it brings a large learning surface. Most of our Apps are lists and text on a 240×135 screen, and full control of the UX is a primary goal.
|
||||
|
||||
## Consequences
|
||||
|
||||
- We write and maintain our own widgets.

||||
- Switching to LVGL later would mean rewriting every App's view layer.

# Signed Update Files checked by the firmware, not ESP32 Secure Boot
|
||||
|
||||
Firmware Updates are accepted only when their Update File carries a valid ECDSA P-256 signature over the image's SHA-256. The firmware itself checks it, against a public key compiled into it, before switching the boot partition. The private key lives outside the repository, in `~/.config/roro9stack/ota-key.pem`.
|
||||
|
||||
We chose this over the ESP32's hardware Secure Boot. Secure Boot is enforced by the chip, but it burns eFuses one-way: a mistake bricks the device, and the device can never run unsigned firmware again, which makes recovery over USB harder. On a single development device, a software check that refuses unsigned pushes is enough, and it stays reversible: a new firmware can carry a new public key.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Someone with physical USB access can still flash anything. Only Wi-Fi and SD card updates are guarded.
|
||||
- **Losing the private key** means the next update has to go over USB, carrying a new public key.
|
||||
- P-256 rather than Ed25519, because the firmware's TLS library (mbedTLS) already verifies it, so it costs no extra code.
|
||||
- **Rollback: the bootloader first, the firmware as a second line.** Arduino-ESP32 marks a new image valid before `setup()` unless the sketch overrides `verifyRollbackLater()`, which once made every update look good and hid the bootloader's rollback (it had looked like the prebuilt bootloader ignored it). With the override, an image stays pending until Probation confirms it, and the bootloader reverts one that restarts unconfirmed, however early it crashes. The firmware also counts its own boots on Probation, very first thing in `setup()`, and reverts itself on the second unconfirmed start.

# A Debug Console over Wi-Fi, in Debug Builds only
|
||||
|
||||
The goal of Firmware Updates is to manage the device without a cable, and that includes finding out what went wrong. So a **Debug Build** (`cardputer-adv-debug`, `-DRORO_DEBUG`, version suffix `+debug`) adds a **Debug Console** on TCP 2323: the serial console, over Wi-Fi. A client sends a token as its first line, then gets the last 4 KB of console output (boot messages included), every new line live, and runs the same commands as the serial port, plus a few that only make sense remotely. ESP-IDF's own log lines are teed into it.
|
||||
|
||||
It's compiled out of release builds entirely, rather than switched off by a setting. A console that runs commands is a remote control: in a release build, nothing listens.
|
||||
|
||||
## How it fits
|
||||
|
||||
- **Console, not Serial.** All human-readable output goes through `console`, which writes to the USB port and, in a Debug Build, to a ring buffer the Debug Console drains. Writes never wait for USB: a host that's attached but not reading used to stall the main loop for up to 2 s per line.
|
||||
- **Commands run on the main loop.** The socket lives on the Debug Console's own task, which only queues command lines. The main loop runs them, as it does serial commands, so they touch Apps and Services from the one task allowed to.
|
||||
- **The token** is 128 random bits in `~/.config/roro9stack/debug-token`, made by the first build and passed into the container. It's never committed; a Debug Build refuses to compile without one. Like the OTA key, it guards against the network, not against someone holding the device.
|
||||
- **One client at a time**, to keep memory flat (4 KB for the ring since M2, 6 KB of task stack).
|
||||
- **Binary commands are answered on the console's own task**, not queued: `get`/`put` (SD card files, run as one Storage Service job each so card access stays on the storage task, with TCP doing the flow control), `screenshot` (the 32 KB RGB332 frame the UI composes into, read as it stands, so it may tear), `coredump get` and `reset`. These keep working when the main loop is stuck. A failed `put` closes the connection, so the rest of the file is never read as commands.
|
||||
|
||||
## Keep a Debug Build in the fallback slot
|
||||
|
||||
Rollback returns to the previous firmware, whatever it is. As long as development goes through Debug Builds, the firmware a crash falls back to has the Debug Console, so a bad update never costs remote access. A release build pushed over a Debug Build leaves the Debug Build in the other slot until the next update overwrites it.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Anyone on the same network with the token can read the console, inject keys and reboot the device. The console never prints stored secrets (Wi-Fi and IRC passwords), but the IRC traffic it shows is readable.
|
||||
- The TCP stream is plain text: fine on a home network, not across the internet.
|
||||
- `+debug` versions compare equal to their release counterparts, so moving between the two is never refused as a downgrade.

# Safe Mode, crash reports and a watched main loop, in every build
|
||||
|
||||
Rollback protects against new firmware that fails Probation. It does nothing for firmware that was confirmed and crashes later: a corrupt setting, a server that sends something unexpected, a bug that takes an hour to show. Without a cable, such a device would restart forever. Three measures, in release and Debug Builds alike, keep it reachable:
|
||||
|
||||
- **Safe Mode.** The firmware counts starts that follow a crash (panic or watchdog) in NVS, first thing at boot. After 3 in a row, it starts only the clock, Wi-Fi, the Update Service and, in a Debug Build, the Debug Console: no Apps, no IRC, no SD card, and a screen that says so with the address to push an update to. Any normal restart (a `reboot`, an update), or a minute of uptime, resets the count.
|
||||
- **Crash reports.** The same boot record keeps which version was running, so after a crash the firmware knows which one crashed, even when a Rollback has switched slots since. ESP-IDF already writes a core dump to its flash partition on a panic; after the restart the firmware prints its summary (task, PC, reason, backtrace) and raises a Notification. The `crash` command shows it again later. In a Debug Build, `scripts/rdbg.py crash` decodes the backtrace and `scripts/rdbg.py coredump` fetches the whole dump for `esp-coredump`, against the ELF of that exact build (`.pio/elves/`, named by version and ELF digest).
|
||||
- **The main loop is watched.** Arduino-ESP32 subscribes only core 0's idle task to the task watchdog, and the main loop runs on core 1: a stuck loop used to hang the device for good, with the screen frozen and the Debug Console unable to run commands. `enableLoopWDT()` makes a loop stuck for 5 s a panic, with a core dump, counted towards Safe Mode. And an installed update no longer depends on the main loop: the Update Service restarts into it by itself after 90 s.
|
||||
|
||||
## Consequences
|
||||
|
||||
- Nothing in the main loop may block for 5 s. Network and card work already run on their own tasks.
|
||||
- Safe Mode can't help when Wi-Fi or the Update Service itself is what crashes; that still needs USB.
|
||||
- Three crashes within a minute of each restart are needed to reach Safe Mode, so a crash loop costs about half a minute before the device becomes reachable.

# The framework is rebuilt with our own SDK settings, for smaller TLS buffers
|
||||
|
||||
Arduino-ESP32 ships its ESP-IDF libraries prebuilt, with one `sdkconfig` for every ESP32-S3 board. Its TLS settings give every connection a 16 KB receive buffer and a 16 KB send buffer for its whole life. On a device with no PSRAM and about 340 KB of RAM, an IRC connection over TLS left a 12.6 KB low in M2, against a 40 KB floor.
|
||||
|
||||
Those settings are compiled into the libraries, so changing them means rebuilding them. pioarduino supports this as a "hybrid compile": `custom_sdkconfig` in `platformio.ini` lists the settings, and the build regenerates the framework's libraries from ESP-IDF (the same 5.5.5 the prebuilt ones come from) before building the app. We set:
|
||||
|
||||
- `MBEDTLS_ASYMMETRIC_CONTENT_LEN`, with 16 KB to receive (servers send full TLS records) and **4 KB to send** (IRC lines are short): 12 KB less per connection.
|
||||
- `MBEDTLS_DYNAMIC_BUFFER`, `DYNAMIC_FREE_CONFIG_DATA`, `DYNAMIC_FREE_CA_CERT`: buffers allocated when needed, and handshake-only data (the CA chain) freed once connected.
|
||||
|
||||
The rebuild also follows the board definition instead of the generic one: PSRAM support is off (the Cardputer ADV has none) and the flash size is 8 MB.
|
||||
|
||||
## Consequences
|
||||
|
||||
- With IRC connected over TLS, a Debug Build has 78 KB free and a 59 KB low (it was 31 KB and 12.6 KB), and 46 KB at the lowest under the heaviest combined load measured (IRC, two refused installs, a 1.6 MB put and get).
|
||||
- The first build after a fresh checkout, or after changing `custom_sdkconfig`, takes about 4 minutes instead of 45 s: it downloads ESP-IDF into the PlatformIO volume and compiles it. Later builds reuse it.
|
||||
- Everything the firmware depends on was checked in the regenerated `sdkconfig`: app rollback, core dumps to flash (ELF), the 5 s task watchdog, FreeRTOS run-time stats, the certificate bundle.
|
||||
- The project now owns its partition table (`default_8MB.csv`, identical to the framework's), which the hybrid build requires. Changing it would break updates over the air: the app slots must stay where they are.
|
||||
- Generated files (`sdkconfig.*`, `managed_components/`, `.dummy/`) are ignored by git.
|
||||
- A TLS server that sends records over 16 KB would still fail, as before; one that needs us to send records over 4 KB would now fail. Neither happens with IRC.

# Our own copy of the SD driver, for one missing byte
|
||||
|
||||
Arduino-ESP32's `SD` library talks to the card over SPI through `sd_diskio.cpp`. That driver gives up on a write without saying why, and about once in 1,500 multi-block writes it gave up on one that had worked (issue #21). A 1.7 MB upload failed about three times in ten; before M3, the retry on top of it then filled the gap with zeros.
|
||||
|
||||
The cause, measured with a driver that records where it stops: after the "Stop Tran" token that ends a multi-block write, a card takes about a byte of clock to signal busy. The driver deselects, selects again, and reads one byte to see whether the card is ready. Read too early, that byte is 0xFF, "ready"; the status check (CMD13) then goes out while the card is still programming, and its answer (0xFF, 0x1F) is taken for an error. Every failure seen was this one: all blocks accepted, then a status that isn't one. ChaN's reference driver, which FatFs ships as its example, sends a dummy byte after selecting the card for this reason. Arduino's doesn't.
|
||||
|
||||
PlatformIO links the framework's library objects directly, so one file can't be replaced from `src`. A project library with the same name takes its place: **`lib/SD` is Arduino-ESP32 3.3.12's SD library (Apache-2.0), with `sd_diskio.cpp` changed** and the other files as they came. The changes are marked `roro:`:
|
||||
|
||||
- A dummy byte after selecting the card, before the ready test, and one after Stop Tran.
|
||||
- Each place a write gives up records the step and the card's answer (`sd_fault.h`): `info` shows the count, and the Debug Console's `put` prints the detail.
|
||||
|
||||
Halving the SPI clock to 10 MHz didn't change the failure rate, so the card stays at 20 MHz.
|
||||
|
||||
## Consequences
|
||||
|
||||
- 30 uploads of 1.7 MB in a row, each read back and compared by SHA-256, ten of them with the LoRa radio listening on the same bus: no write fault. Before: 3 failures in 10.
|
||||
- Every writer gains: Logs, Tracks, Gemini pages, Saved Pages, Captures and Update Files installed from the card all go through this driver, and none of them checked.
|
||||
- **The copy has to follow the framework.** When the platform is updated, compare `lib/SD` with the new `libraries/SD` and carry the `roro:` changes over. If upstream fixes the ready test, drop the copy. Reported as [arduino-esp32#12970](https://github.com/espressif/arduino-esp32/issues/12970); issue #39 follows it.
|
||||
- One more defect was read in the code and left alone, because nothing here exercises it: the driver tests the card's answer to a data block against 0x0A and 0x0C, values it can't take (accepted is 0x05, CRC error 0x0B, write error 0x0D), so a block rejected for a CRC error is never resent. No such rejection was seen in any failure. If `DataToken` faults ever show in `info`, that's the next fix.
|
||||
- A fault is now counted and explained instead of silent, so the next cause, if there is one, starts with evidence.

# G1 — Gemini client
|
||||
|
||||
**Status:** done, tagged v0.5.0. Every step was checked on the device; reading Saved Pages with Wi-Fi off was checked by hand (2026-10-05).
|
||||
|
||||
**Goal:** browse Geminispace from the Cardputer: fetch and read gemtext over TLS, follow links, answer input prompts, keep bookmarks, and save pages to the SD card to read later, offline. A side milestone between M2 and M3, tagged v0.5.0 when done.
|
||||
|
||||
Gemini (geminiprotocol.net): one request per TLS connection on port 1965, the request is the URL and CRLF, the response a `<status> <meta>` header line, then the body. Most capsules use self-signed certificates: trust on first use is the norm.
|
||||
|
||||
## Decisions (design round 2026-10-05)
|
||||
|
||||
| # | Decision |
|
||||
|---|---|
|
||||
| Q70 | A milestone of its own, **G1**, before M3: plan, tests first, measured on the device, tagged v0.5.0. |
|
||||
| Q71 | **TOFU:** the first certificate seen for a host is pinned (SHA-256, in NVS). If it changes, the page isn't shown; a dialog shows both fingerprints and asks whether to trust the new one. Self-signed or expired certificates are fine; only a change counts. |
|
||||
| Q72 | Responses: 1x input (11 hidden, for passwords), 2x content, up to 5 redirects (3x), 4x/5x errors with the server's message. 6x (client certificates): "not supported". |
|
||||
| Q73 | `text/gemini` is rendered, other `text/*` shown as plain text. Anything else can be saved to `/gemini/downloads/`, not shown. |
|
||||
| Q74 | Up to **64 KB on screen**, larger pages truncated with a notice. Saving streams to the card, so a larger page is saved whole. |
|
||||
| Q75 | Gemtext rendering: text wrapped to the 40-column screen; `#`/`##`/`###` headings in bold and accent; `*` lists with bullets; `>` quotes indented and muted; preformatted blocks unwrapped, Left/Right to scroll; `=>` links with their label, numbered. |
|
||||
| Q76 | Up/Down scroll; Tab and Shift+Tab move between links; Enter follows; Backspace goes back; `g` opens the address line. Links to other protocols show their URL and aren't followed. |
|
||||
| Q77 | Back history of 20 URLs in RAM, with scroll positions; going back refetches (or reopens a Saved Page). **Bookmarks** in `/gemini/bookmarks.gmi` (a gemtext page, shown on the start page); `b` adds the current page. Without a card, a built-in start page. |
|
||||
| Q78 | Start page: bookmarks, then Saved Pages, then defaults: geminiprotocol.net, a search engine (kennedy.gemi.dev), an aggregator (Cosmos; Antenna was down when measured). |
|
||||
| Q79 | UTF-8 decoded; characters outside the Latin-1 fonts shown as `?`. |
|
||||
| Q80 | IRC and Gemini can run together: each fetch opens one connection, reads and closes it. If there isn't memory for a second TLS connection, the fetch fails with a clear message and IRC is untouched. Measured in step 1. |
|
||||
| Q81 | Debug aid: `gemini get <url>` prints the status, MIME type, size, certificate fingerprint and the first lines. URL resolution (RFC 3986), the response header and gemtext parsing are host-tested. |
|
||||
| Q82 | `s` saves the page on screen as a **Saved Page**: `/gemini/saved/<host>/<path>.gmi`, the gemtext as received plus a first line with its URL and save date. Saving again replaces it, and says so. |
|
||||
| Q83 | `S` saves the page and the pages it links to, one level deep: gemtext only, same host only, at most 30 pages, in the background with a progress Toast. |
|
||||
| Q84 | The start page lists Saved Pages, newest first, grouped by capsule; they open with no network. In a Saved Page, a link to another Saved Page opens the saved copy; other links fetch online if Wi-Fi is up, or say "not saved, offline". A Saved Page shows when it was saved; `r` refreshes it. |
|
||||
| Q86 | *Decided after step 1, revised after Q88.* **Two floors:** free heap stays above 40 KB in steady state; a fetch refuses to start below **55 KB** free ("not enough memory: stop IRC or retry"). The firmware's own allocations during a fetch (a page in RAM, a window) keep 20 KB free. With IRC connected, the TLS connection itself can briefly take the heap lower, depending on the server's record sizes: measured 24, 19.5, 15.5 and **13 KB**. *Accepted:* about 12 KB for a moment during a fetch with IRC up, rather than refusing most fetches (a 70 KB start floor) or dropping IRC's connection for each page. |
|
||||
| Q87 | *Decided in step 3.* **With a card, every page streams to `/gemini/cache/page.gmi`** in 1 KB pieces while its TLS connection is open; once the connection closes and its ~45 KB is back, the page is loaded into RAM as far as the 40 KB floor allows. The whole page stays on the card (Saved Pages copy it). Without a card, the page goes straight to RAM under the same two floors. Pages are held as lines in 4 KB chunks, never one large block (the largest free block with IRC connected is about 31 KB). |
|
||||
| Q88 | *Added after step 6.* **A page bigger than memory allows is read from the card as you scroll.** Opening it, one pass over its file counts the lines, records where every 64th starts (and whether it's inside a preformatted block), and loads the first window. Scrolling near either end of the window reads the next or previous one in the background, keeping the line on top of the screen where it is; the scrollbar follows the whole page. Display pages alternate between two cache files, so the one on screen is never overwritten by the next fetch; background jobs use a third. |
|
||||
| Q85 | Saved Pages are deleted from the App only (`d`, with confirmation), never by Storage Clean-up's age rules, like Notes. |
|
||||
|
||||
## Measured (step 1)
|
||||
|
||||
- `gemini://geminiprotocol.net/`: `20 text/gemini`, 1,184 bytes, TLS handshake 0.7–1.1 s, whole fetch 0.7–1.1 s; kennedy.gemi.dev 1.9 s. The fetch task's stack peaks at about 3.6 KB of 6.
|
||||
- **Heap, Debug Build, IRC connected over TLS:** about 68 KB free before a fetch. After the handshake the fetch holds about 32 KB (36–40 KB left); the handshake itself (certificate chain parsed with the 16 KB receive buffer allocated) dips to about **24 KB** for a second or two. Nothing leaks: the heap after matches the heap before.
|
||||
- **Step 3, Cosmos (31.6 KB) with IRC connected:** first stopped at 4.6 KB (RAM only, the transfer's 20 KB floor). Streamed to the card: the whole page on the card, 20 KB of it loaded, lowest free heap 19.5 KB during the transfer and 43 KB once loaded. Without IRC: the whole page in RAM. Redirects (Cosmos `31`), input (`10`), not found (`51`) and a changed certificate (refused, both fingerprints shown) all checked on the device.
|
||||
- **Steps 4–6 on the device:** Project Gemini and its relative links, Back with the scroll restored, a refused YouTube link; `b` bookmarks, `s` saves (and says when it replaced an older copy), `S` saved 6 of 6 pages, the start page lists both; a Saved Page opens from the card with its origin, its saved links open saved copies, `r` refreshes, `d` asks first; Kennedy's input prompt sent "cardputer" and got 87 results; emoji drawn as `?`.
|
||||
- **A bug found there:** refreshing first loaded the whole Saved Page into RAM just to read its origin, next to the App's copy and a TLS connection: the heap fell to 436 bytes. Now only the first line is read, and every fetch (pages, saves, refreshes) checks the 55 KB start floor. Lowest since boot afterwards: 53.8 KB.
|
||||
- **Windowed pages (Q88), Cosmos with IRC connected:** 226 of 419 lines in memory at first; paging down loaded lines 192–419 in one window, scrolling back up loaded 64 onwards, then 0 onwards. Window budgets count the memory the old window gives back.
|
||||
- **Heap during a fetch with IRC connected:** lowest 13–15.5 KB in later runs (24 and 19.5 KB earlier), the TLS receive buffers varying with the server's records. Accepted (Q86, revised).
|
||||
- Antenna (`warmedal.se`) doesn't answer, from the PC either; the default aggregator becomes Cosmos (`gemini://skyjake.fi/~Cosmos/`, which redirects to `cosmos.skyjake.fi`).
|
||||
|
||||
## Done when
|
||||
|
||||
- `gemini get gemini://geminiprotocol.net/` prints the header, size and fingerprint on the console.
|
||||
- The Gemini App opens the start page, follows links (relative ones included), goes back, and follows redirects.
|
||||
- An input prompt (e.g. a search) takes a query and shows the results.
|
||||
- A changed certificate stops the page and asks.
|
||||
- `s` saves a page, `S` a page and its links; with Wi-Fi off, Saved Pages open and their saved links work.
|
||||
- Bookmarks are added with `b` and listed on the start page.
|
||||
- With IRC connected over TLS, a fetch still works, and the free heap stays above 40 KB.
|
||||
|
||||
## Work breakdown
|
||||
|
||||
1. **Two TLS connections:** measure the heap with IRC connected while a Gemini fetch runs.
|
||||
2. **Parsers** (host-tested): URL parsing and relative resolution, the response header, gemtext lines.
|
||||
3. **Fetch** on its own task, with TOFU and `gemini get`.
|
||||
4. **Gemini App:** rendering, scrolling, links, history, the address line.
|
||||
5. **Input prompts, redirects, bookmarks, downloads.**
|
||||
6. **Saved Pages,** then saving with linked pages.

# M0 — Skeleton: Launcher, Status Bar, Settings, battery
|
||||
|
||||
**Status:** done on 2026-10-02, tagged `v0.1.0`.
|
||||
|
||||
## Outcome
|
||||
|
||||
Every "Done when" item below works on the device, apart from the gaps listed here. Changes made along the way:
|
||||
|
||||
- **Not done, carried over:**
|
||||
- **Charging indicator:** the battery voltage alone can't tell charging apart reliably. Revisit if the hardware exposes a charger status.
|
||||
- **Waking from power-off with a keyboard key:** G0 only for now.
|
||||
- **Status Bar placeholders** for GNSS, mesh, Wi-Fi and unread count are left out until those Services exist (M1, M2, M4).
|
||||
- **Added:**
|
||||
- **SD card erase**, in Settings → Storage.
|
||||
- **A Notification wakes an Off screen** (dimmed) while its Toast shows.
|
||||
- **Navigation arrows without Fn** outside Text Entry.
|
||||
- **Serial dev commands** and `scripts/serial_log.sh`.
|
||||
- **Measured on the device:**
|
||||
- About 225 KB free heap with the 64 KB frame buffer.
|
||||
- About 15 ms per frame.
|
||||
- 19% of the app flash used.
|
||||
|
||||
**Goal:** a firmware you can flash and hold. It boots to a Launcher, shows a live Status Bar, navigates with the keyboard and saves Settings. It proves the App/Service architecture that every later milestone plugs into.
|
||||
|
||||
## Done when
|
||||
|
||||
- Building, testing and flashing each work with one command, run inside a local Docker container (no toolchain on the host).
|
||||
- First boot runs the setup wizard (names, Region, timezone), and later boots skip it.
|
||||
- The Launcher lists Apps. Enter starts one, `` ` `` goes back, and Fn+`` ` `` returns home from anywhere.
|
||||
- The Status Bar shows battery %, a charging indicator and the clock (relative until set), with placeholders for GNSS, mesh, Wi-Fi and unread count.
|
||||
- The Settings App edits and persists: long and short name, Region, timezone, brightness, dim and off timeouts, sound on/off, and probe-request MAC handling (raw by default).
|
||||
- An About screen shows the version, free heap, battery voltage, SD status and usage, and uptime.
|
||||
- The screen dims at 30 s and turns off at 60 s. Any key wakes it without the key also acting on the App.
|
||||
- A long press of G0 powers off (deep sleep). G0 or a key wakes the device.
|
||||
- The Compose Key types accented characters in the line editor (`opt` `'` `e` → é).
|
||||
- Toast Notifications work. A demo App can raise one, with a beep and LED flash.
|
||||
- SD usage is watched: a Storage Warning appears once per boot above 80%. The Log-write cutoff flag is set at 90%, with no Log writers yet.
|
||||
|
||||
## Out of scope for M0
|
||||
|
||||
Storage Clean-up screen (M1, once IRC Logs exist), any radio, GNSS, Wi-Fi.
|
||||
|
||||
## Work breakdown
|
||||
|
||||
1. **Project scaffold**
|
||||
- PlatformIO project with the pioarduino platform (Arduino-ESP32 3.x on ESP-IDF 5.x). Board `m5stack-stamps3`, 8 MB partitions, USB-CDC on boot.
|
||||
- Dependencies: `M5Cardputer` (pulls in M5Unified and M5GFX).
|
||||
- `LICENSE` (GPL-3.0), `README.md` with build and flash steps, a version string injected from git at build time (semver tags).
|
||||
- A `native` environment for host-side unit tests (Unity).
|
||||
- **Local CI** in a Docker image with PlatformIO. One script builds the firmware and runs the native tests, and the same container flashes over USB. The repo is hosted on self-hosted Gitea, and a Gitea Actions workflow can reuse this image later.
|
||||
2. **Hardware bring-up checks** (manual, on the device)
|
||||
- Display, keyboard (TCA8418) and speaker through M5Cardputer.
|
||||
- Confirm there's no PSRAM, and record the heap at boot.
|
||||
- Investigate the G38 backlight/LED power-rail coupling, then decide how dimming works without killing the LED.
|
||||
- Battery ADC on G10 (×2 divider): calibrate the voltage-to-% curve.
|
||||
- SD card mount on the shared SPI bus (CS=12), behind a bus lock ready for the LoRa radio in M3.
|
||||
3. **Core runtime**
|
||||
- **Event bus:** Services publish events (battery changed, notification, storage threshold), and the UI consumes them on the UI task.
|
||||
- **Service interface:** start, stop, periodic tick, state snapshot for the Status Bar.
|
||||
- **App interface:** enter, exit, key event, draw. Plus a registry, so adding an App means one file and one registration line.
|
||||
- **App lifecycle:** one foreground App; Home and Back handling.
|
||||
4. **Services for M0**
|
||||
- **Settings store:** typed keys in NVS (internal flash), with defaults and change events.
|
||||
- **Battery Service:** sampled voltage, smoothed %, charging detection if the hardware allows it.
|
||||
- **Clock Service:** no time source yet. API for "set from source X", plus relative-time formatting and Europe/Brussels conversion.
|
||||
- **Storage Service:** SD present/absent, usage %, 80% and 90% thresholds raising events, Log-write permission flag.
|
||||
- **Power Service:** dim and off timers, wake-key swallowing, G0 long-press → deep sleep.
|
||||
5. **Widget kit** (ADR 0002): an off-screen buffer pushed to the display.
|
||||
- Status Bar, list, text view, line editor (with the Compose Key), dialog and Toast.
|
||||
- A Latin-1 font set.
|
||||
6. **Input layer**
|
||||
- Map key events to logical keys: arrows (Fn + `;` `.` `,` `/`), Back, Home, Select.
|
||||
- Compose Key dead-key state machine. This is pure logic, unit-tested on the host.
|
||||
7. **Apps:** Launcher, Settings (including About), first-boot wizard, and a hidden Demo App for exercising Toasts and widgets.
|
||||
8. **Docs:** a short walkthrough for a first-time setup: install PlatformIO, USB permissions on Linux, flash, recover via download mode.
|
||||
|
||||
## Host-tested logic (TDD candidates)
|
||||
|
||||
- Compose Key state machine
|
||||
- Battery voltage → % curve and smoothing
|
||||
- Storage threshold and once-per-boot warning logic
|
||||
- Relative-time formatting and timezone conversion
|
||||
- Settings defaults and validation (e.g. Region must be confirmed before any transmit flag)
|
||||
|
||||
## Risks to resolve early
|
||||
|
||||
- **G38 shared rail:** if the backlight and LED really share power, "screen off" may also need to turn the LED off.
|
||||
- **RAM headroom:** the off-screen buffer is 240×135×2 ≈ 64 KB at 16-bit, or about 32 KB at 8-bit. Measure the free heap now, because Wi-Fi + TLS (M1) is the tightest point.
|
||||
- **Keyboard library maturity** for the ADV's TCA8418 in `M5Cardputer`. Fall back to Adafruit_TCA8418 directly if needed.

# M1 — Wi-Fi Service, Wi-Fi Tools, IRC
|
||||
|
||||
**Status:** done on 2026-10-03, tagged `v0.2.0`.
|
||||
|
||||
## Outcome
|
||||
|
||||
The "Done when" items below work on the device, against irc.libera.chat over TLS, with the following changes.
|
||||
|
||||
- **Changed:**
|
||||
- **Wi-Fi Tools is built from ordinary scans only:** networks nearby, channel occupancy and a signal tracker. Monitoring-mode views and captures are deferred (revised Q42). The Monitoring mode stays in the Wi-Fi Service and the IRC pause logic, unused for now.
|
||||
- **The frame buffer is 8-bit colour** (Q46), applied as soon as IRC on TLS measured a 51 KB low.
|
||||
- **Not done, carried over:**
|
||||
- **Wi-Fi scan logs** (a CSV of the access points each scan sees) can be recorded from Wi-Fi Tools; monitoring-mode captures remain deferred.
|
||||
- **IRC has no input history** (up-arrow recall). Each Buffer keeps only 50 lines in RAM; the full history is in the Logs.
|
||||
- **Measured on the device:**
|
||||
- With Wi-Fi and IRC on TLS: about 92 KB free heap, about 77–81 KB at the lowest. The floor was 40 KB.
|
||||
- 44% of the app flash used.
|
||||
- 231 host tests.
|
||||
|
||||
**Goal:** the device joins your Wi-Fi by itself, syncs its clock, keeps an IRC session alive in the background, and gives passive Wi-Fi diagnostics with full-frame captures.
|
||||
|
||||
## Decisions (design round 2026-10-02)
|
||||
|
||||
| # | Decision |
|
||||
|---|---|
|
||||
| Q40 | Up to 8 **Saved Networks**, joined strongest-first. Added from a scan or as a hidden network. Open networks are allowed; enterprise (802.1X) is not. |
|
||||
| Q41 / Q48 | The Wi-Fi Service stays **Connected** whenever enabled and a Saved Network is in range. Settings has a Wi-Fi On/Off switch. **Monitoring** happens only while Wi-Fi Tools is open; the device reconnects on exit. |
|
||||
| Q42 | *Revised 2026-10-02:* Wi-Fi Tools is built from ordinary scans only (access points, channel occupancy, signal tracker). Monitoring-mode views and captures are deferred, to be revisited later. |
|
||||
| Q43 | The signal tracker clicks faster as the signal gets stronger. On by default, mutable. |
|
||||
| Q44 | IRC shows one Buffer at a time; Tab cycles Buffers. Commands: `/join /part /msg /me /nick /topic /names /quit /raw`. Logs go to `/irc/<network>/<buffer>/YYYY-MM-DD.log`. |
|
||||
| Q45 | TLS verifies server certificates against the bundled certificate authorities. Per server, a self-signed certificate can be pinned on first use. |
|
||||
| Q46 | If RAM is short: switch the frame buffer to 8-bit colour. Keep the AtomS3 Wi-Fi co-processor in mind. |
|
||||
| Q47 | Passwords are stored in NVS without flash encryption (revisit before any public release). |
|
||||
| IRC | The **IRC Service** stays connected in the background once the App has started it, until `/quit` or disconnect. It does not start at boot. |
|
||||
| Q49 | Opening a Monitoring view while IRC is connected asks first. IRC then pauses, and reconnects and rejoins afterwards; its Buffers show the gap. |
|
||||
| Q50 | Reconnects after drops wait 5 s, 10 s, 30 s … up to 5 min. |
|
||||
| Q51 | Mentions and private messages raise Notifications. Other traffic only counts as unread (Status Bar shows the total). |
|
||||
| M0 | The **Storage Clean-up** screen lands here, once IRC Logs and Captures exist. |
|
||||
|
||||
## Done when
|
||||
|
||||
- Wi-Fi joins the strongest Saved Network at boot. The Status Bar shows Wi-Fi state, and the clock is set over NTP.
|
||||
- Settings → Wi-Fi: On/Off, scan and add a network (with password), add a hidden network, forget a network.
|
||||
- The IRC App configures one server (host, port, TLS, nick, SASL or NickServ, auto-join IRC channels). It connects and keeps running after you leave the App. Mentions notify.
|
||||
- IRC reconnects after Wi-Fi loss or a server drop, and rejoins its IRC channels. Logs are written to the SD card (and stop past 90% usage).
|
||||
- Wi-Fi Tools: access-point list, channel occupancy with the quietest of channels 1/6/11, and a signal tracker that clicks faster as the signal gets stronger. None of it interrupts the connection or IRC.
|
||||
- Settings → Storage → Clean-up deletes IRC Logs, probe Logs and Wi-Fi Captures older than a chosen age, with a preview of the space freed.

## Work breakdown (proposed order)
|
||||
|
||||
1. **Memory baseline:** measure the heap with Wi-Fi Connected plus one TLS connection. Switch the frame buffer to 8-bit if the margin is too thin.
|
||||
2. **Wi-Fi Service:**
|
||||
- Saved Networks in NVS.
|
||||
- Choosing the network (host-tested).
|
||||
- The Off / Connecting / Connected / Monitoring state machine (host-tested).
|
||||
- NTP → Clock.
|
||||
- Status Bar indicator.
|
||||
- Settings → Wi-Fi pages.
|
||||
3. **Log writing:** a Log writer that respects the Storage rules, daily files, and the Storage Clean-up screen (selection logic host-tested).
|
||||
4. **IRC Service** (host-tested core):
|
||||
- message parser and serializer;
|
||||
- registration, SASL PLAIN and NickServ;
|
||||
- PING/PONG;
|
||||
- Buffers with unread counts and Mention detection;
|
||||
- reconnect backoff, and pause/resume around Monitoring.
|
||||
|
||||
Then the TLS transport with the certificate bundle.
|
||||
5. **IRC App:** Buffer view, input line, command parser (host-tested), server settings page.
|
||||
6. **Wi-Fi Tools App:** access-point list, channel occupancy and signal tracker from scans (occupancy and tracker logic host-tested). Monitoring mode is deferred.

# M2 — GNSS
|
||||
|
||||
**Status:** done on the device (branch `m2`): every "Done when" item below is met.
|
||||
|
||||
## Measured
|
||||
|
||||
- **Cold start** (`$PCAS10,2`) to a 3D Fix, by a window: **73 s**, 5 satellites used of 8 in view. A restart of the ESP32 alone keeps the receiver's Fix (the Cap stays powered).
|
||||
- By a window: 3D Fix from GPS, GLONASS, Galileo and BeiDou, up to 14 of 17 satellites used, HDOP 1.0–1.3.
|
||||
- **Heap, Debug Build, GNSS on, IRC on TLS** (floor 40 KB; v0.2.1 had a 79 KB low):
|
||||
|
||||
| | Free | Lowest |
|
||||
|---|---|---|
|
||||
| Start of M2 | 31 KB | 12.6 KB |
|
||||
| Stacks and buffers trimmed by measurement | 46 KB | 18 KB |
|
||||
| mDNS removed | 54 KB | 34 KB |
|
||||
| Framework rebuilt with smaller TLS buffers (ADR 0006) | **78 KB** | **59 KB** |
|
||||
|
||||
Under the heaviest combined load measured (IRC, two refused installs, a 1.6 MB put and get), the low is 46 KB. The cost had come mostly from the OTA and Debug Build work, not GNSS. Stacks were set to measured peak plus about 2 KB (loop 6 KB, update 5, storage 6, irc 6); after a TLS handshake the irc task has 1.7 KB left. IRC can now be stopped by hand (`/quit` in any state, `irc stop`), which frees its TLS memory.
|
||||
|
||||
**Goal:** the device knows where it is and what time it is without a network: a GNSS Service in the background, a GNSS App with the position and a sky view of the satellites, the clock set from satellites when there's no NTP, and Tracks recorded to the SD card.
|
||||
|
||||
**Hardware:** the Cap LoRa-1262 carries an ATGM336H-6N (AT6668), multi-constellation (GPS, BeiDou, Galileo, GLONASS, QZSS), with a ceramic antenna. NMEA over UART, 115200 8N1. **Measured (step 1, `gnss probe`): RX GPIO 15, TX GPIO 13, 115200 8N1**, as in Meshtastic's board file; M5Stack's page names GPIO 8 and 9, which are the internal I2C bus the keyboard controller sits on. Output is NMEA 4.10 style: `GN` RMC, VTG and GGA, one GSA per constellation with the system ID (1 GPS, 2 GLONASS, 3 Galileo, 4 BeiDou, 5 QZSS) in its last field, and a GSV sequence per constellation and signal (`GP`, `GL`, `GA`, …) with the signal ID last. RMC carries a time even without a Fix (status `V`), so only a Fix makes it trustworthy.
|
||||
|
||||
## Decisions (design round 2026-10-04)
|
||||
|
||||
| # | Decision |
|
||||
|---|---|
|
||||
| Q58 | Settings has a GNSS On/Off switch, **On by default**. Off puts the receiver in standby. *Measured:* `$PCAS12,<seconds>` (CASIC) stops its output within a second, for up to at least 65535 s, and any command wakes it within a second; Off sends `PCAS12,65535` (renewed hourly), On sends a hot start, `PCAS10,0`. |
|
||||
| Q59 | The **GNSS App** has two views, switched with Tab. *Position*: latitude, longitude, altitude, speed, course, Fix (none / 2D / 3D), satellites used and in view, HDOP, UTC time. *Sky*: the satellites placed by azimuth and elevation, coloured by constellation, filled when used in the Fix. |
|
||||
| Q60 | "Radar" in M2 means the Sky view. A radar of other Nodes by distance and bearing needs the mesh: M4. |
|
||||
| Q61 | The **Status Bar** shows a GNSS mark: absent when off, muted while searching, normal with a 2D Fix, with the satellite count with a 3D Fix. |
|
||||
| Q62 | GNSS time **sets the clock once there's a Fix**, and refreshes it every 10 minutes. *Revised in step 3:* the clock's trust order from M0 (Mesh < NTP < GNSS) already ranks GNSS above NTP, which is right: GNSS time is at least as accurate. So GNSS also corrects a clock NTP set, not only an unset one. |
|
||||
| Q63 | A **Track** is started and stopped in the GNSS App. It's written as GPX to `/gnss/tracks/<YYYYMMDD-HHMMSS>.gpx`, a point every 5 s when the position moved more than 5 m. It keeps recording with the App closed, with a Toast on start and stop and a Status Bar mark, and gets its own Storage Clean-up category. |
|
||||
| Q64 | Coordinates in **decimal degrees plus the Maidenhead locator**; a Settings switch for degrees, minutes and seconds. Metric units only. |
|
||||
| Q65 | **The position never leaves the device in M2.** Sharing it over the mesh, and at what precision, is decided in M4. |
|
||||
| Q66 | **Our own NMEA parser**, host-tested: RMC, GGA, GSA and GSV, with each talker ID mapped to its constellation. TinyGPSPlus (named in ADR 0001) doesn't track the satellite list across constellations, which the Sky view needs. |
|
||||
| Q67 | The receiver keeps its **defaults** (all constellations, 1 Hz). No receiver settings. Time to first fix is measured and recorded here. |
|
||||
| Q68 | Debug aids: `gnss status`, and `gnss nmea on/off` to stream the raw sentences to the console (USB serial and Debug Console). Raw NMEA is never written to the card. |
|
||||
|
||||
**Lesson (step 3):** the first probe also tried the pins swapped, driving the receiver's output line from the ESP32 for about a second. The receiver then went silent until a full power cycle (an ESP32 restart doesn't cut the Cap's power). Never drive GPIO 15.
|
||||
|
||||
## Done when
|
||||
|
||||
- The GNSS Service reads NMEA in the background whatever App is on screen, and a 3D Fix appears outdoors.
|
||||
- The GNSS App shows the Position and Sky views, both live.
|
||||
- The Status Bar shows the GNSS mark per Q61.
|
||||
- With no Wi-Fi, the clock is set from GNSS after the first Fix.
|
||||
- A Track records while the App is closed, survives the screen turning off, and opens as valid GPX on the PC.
|
||||
- Settings → GNSS Off stops it (and the Status Bar mark goes away); On brings it back.
|
||||
- Free heap stays above about 40 KB with GNSS, Wi-Fi, IRC on TLS and the UI running.
|
||||
|
||||
## Work breakdown
|
||||
|
||||
1. **Hardware check:** a `gnss probe` command reads the candidate UART pins and reports which carries NMEA, at what baud rate, and which talker IDs. Then the standby command (Q58) and a first time to first fix.
|
||||
2. **NMEA parser** (host-tested): checksum, RMC, GGA, GSA, GSV across constellations, merged into one GNSS state (Fix, position, time, satellites).
|
||||
3. **GNSS Service:** UART on its own task, the parser, `gnss status` and `gnss nmea`, Settings On/Off.
|
||||
4. **Clock from GNSS** (Q62), and the Status Bar mark (Q61).
|
||||
5. **GNSS App:** Position view, Maidenhead and coordinate formats (host-tested), then the Sky view.
|
||||
6. **Tracks:** the 5 s / 5 m rule and GPX writing (host-tested), background recording, Clean-up category.

# M3 — Radio bring-up: the LoRa Scanner
|
||||
|
||||
**Status:** done, tagged v0.6.0. Everything was checked on the device except one "Done when" item: Sweep was never tried against a known transmitter (see below). The listening hour heard nothing, so by Q104 **a reference Meshtastic node is a requirement for M4**.
|
||||
|
||||
**Goal:** the LoRa radio on the Cap works, receive only: a Radio Service owns it and shares the SPI bus with the SD card safely, and a LoRa Scanner App shows what's on the air, either packets (Sniffer) or energy across the band (Sweep). Nothing in M3 can transmit. The mesh comes on top of this in M4 (receive) and M5 (transmit).
|
||||
|
||||
**Hardware:** the Cap LoRa-1262 carries an SX1262 (868–923 MHz, +22 dBm) with an RP-SMA antenna. Pins, as in Meshtastic's board file for the Cardputer ADV: **NSS 5, RST 3, DIO1 (IRQ) 4, BUSY 6**, on the SPI bus shared with the microSD card (SCK 40, MISO 39, MOSI 14; card CS 12). Meshtastic uses DIO2 as the RF switch and DIO3 for a 1.8 V TCXO, marked optional. M5Stack's page adds an FM8625H antenna switch enabled by P0 of a PI4IOE5V6408 I/O expander on the internal I2C bus, address not given; Meshtastic doesn't mention it. Step 1 measures which is true.
|
||||
|
||||
**No other LoRa device yet.** meshmap.net (2026-10-05) lists two Meshtastic nodes within 10 km of the desk and six within 30 km, with positions blurred by a few km; none is known to be in range. M3 needs none: it only receives.
|
||||
|
||||
## Measured
|
||||
|
||||
- **Internal I2C bus (8/9):** 0x18 (ES8311 codec), 0x34 (TCA8418 keyboard), **0x43 (PI4IOE5V6408, ID register 0xA2)**, 0x69 (BMI270 IMU).
|
||||
- **The SX1262 answers** on NSS 5, RST 3, DIO1 4, BUSY 6. Its version string reads `SX1261 V2D 2D02`, which SX1262 chips report too. **The 1.8 V TCXO works** on the first try; the radio is ready 38 ms after `begin`.
|
||||
- **The expander's P0 connects the antenna; it's required.** At power-on P0 is an input (direction 0x00, high-impedance 0xFF), and the receiver reads a flat **-111.9 dBm** at 869.525 MHz, BW 250 kHz: the chip's own floor, deaf. With P0 driven high, the noise floor is **-87 to -94 dBm**: the antenna hearing the room. So the Radio Service drives P0 high at boot (Q91).
|
||||
- **DIO2 doesn't change reception** (within ±2 dB over three runs, P0 high). It likely selects TX versus RX in the FM8625H; it stays the RF switch, as in Meshtastic.
|
||||
- **The noise floor at the desk is high** (-87 to -94 dBm, varying run to run), about 25 dB above thermal noise for 250 kHz. Something nearby is loud, possibly the Cardputer itself or the PC; Sweep (step 5) should show where it sits.
|
||||
- **Step 2:** presets, frequencies and the channel hash are checked against Meshtastic's source (`MeshRadio.h`, `RadioInterface.cpp`): LongFast and the default key give hash 8, MediumFast 31, as Meshtastic shows. Captures were checked with TShark 4.2.5: every LoRaTap field reads back. Wireshark ignores the spec's quarter-dB packet RSSI below 0 dB SNR, so packet RSSI is plain dBm.
|
||||
- **Step 3:** the DIO1 interrupt works (a 100 ms receive timeout wakes the task after 105 ms). While listening: four 1.7 MB uploads and Gemini pages to the card, no radio or card errors (the card refuses a write about once in five uploads with the radio asleep too; `put` now catches it, and issue #21 follows the cause). The ring takes 9.8 KB while listening; the radio task's stack peaks at 2.0 KB.
|
||||
- **No packets yet, and a loud desk.** Twenty minutes on LongFast and on LoRaWAN's three uplink frequencies (SF7, SF9, SF12): no packet and no header, valid or not. The noise floor reads -83 to -94 dBm, against -112 dBm with the antenna switched off: 20 to 30 dB lost to something nearby, not the screen and not the GNSS receiver. Preamble detections are false alarms at this noise level (more on an empty frequency, 869.0 MHz, than on LongFast).
|
||||
- **Step 4:** a Capture made on the device reads back in TShark field for field (time, frequency, SF, RSSI, SNR, payload). A Capture keeps the radio listening with the App closed; stopping it puts the radio back to sleep.
|
||||
- **Step 5:** a pass across 863–870 MHz (71 steps, the strongest of three RSSI readings at each, measured at 125 kHz) takes about 607 ms. At the desk the band is **flat at -100 to -102 dBm**, about 15 dB above the chip's own floor at 125 kHz, with a steady carrier at 863.2 MHz (-89 dBm at its strongest) and fainter lines elsewhere: broadband noise from nearby electronics rather than a transmitter. Sweep's waterfall takes 2.6 KB while shown; 91.9 KB free during a Sweep. The radio task's stack peaks at 1.9 KB.
|
||||
- **Outside, on battery (step 6).** The noise is no lower than at the desk: a Sweep floor of -96 to -99 dBm (median -97) with Wi-Fi on, -99 to -100 with Wi-Fi off, so Wi-Fi accounts for 2 or 3 dB. The same narrow peaks come back on every pass, at 863.2, 863.6, 864.4, 864.8, 865.9, 866.3, 867.8, 869.0 and 869.4 MHz (-88 to -91 dBm), several of them 400 kHz apart; 869.4 MHz is the lower edge of LongFast's channel. A source that follows the device outside and onto its battery is the device: **about 15 dB of the floor is the Cardputer's own** (issue #20). At SF11 that puts the weakest decodable packet near -114 dBm on LongFast, against about -130 dBm for a quiet receiver.
|
||||
- **The listening hour (step 6, Q104):** 20:33 to 21:34 on 2026-10-05, outside, on battery, LongFast, with a Capture running. **0 packets, 0 headers**, 0 radio errors; noise -85 to -87 dBm at 250 kHz throughout; 860 preamble detections, all false alarms. The Capture holds its 24-byte header and nothing else. No restart in 1 h 10 min.
|
||||
- **Floors (Q86):** with the radio listening, Wi-Fi and IRC connected over TLS, 52.6 KB free (lowest 22.7 KB during the TLS handshake, the dip accepted in G1). Without IRC, 93 KB.
|
||||
- **Receive only:** nothing in `src` or `lib` calls a transmit function.
|
||||
- **Cost:** RadioLib 7.8.1 and the probe add 23.6 KB of flash and 656 bytes of static RAM to the release firmware (1,679,843 bytes of 3,342,336). The whole milestone: 51.8 KB of flash (1,708,091 bytes), 365 tests (27 new).
|
||||
|
||||
## Decisions (design round 2026-10-05)
|
||||
|
||||
| # | Decision |
|
||||
|---|---|
|
||||
| Q89 | **M3 is the radio only:** Radio Service, Sniffer, Sweep. Notes and the File Browser (Q30) move out to issue #3 and a Notes issue, as a later side milestone. |
|
||||
| Q90 | **RadioLib**, pinned (ADR 0001). SX1262 on NSS 5, RST 3, DIO1 4, BUSY 6; DIO2 as RF switch; TCXO at 1.8 V tried first, falling back to the crystal (Meshtastic's `TCXO_OPTIONAL`). |
|
||||
| Q91 | Step 1 is `lora probe`: chip status and version, which oscillator setting worked, and an I2C scan of the internal bus for the PI4IOE5V6408. If present, its P0 is set high at boot (harmless) and DIO2 stays the switch. A wrong switch receives deaf, so compare noise floors. |
|
||||
| Q92 | A **Radio Service** owns the SX1262: driver, bus lock, IRQ task. The LoRa Scanner uses it in M3; the Mesh Service sits on top of it in M4. |
|
||||
| Q93 | Every radio transfer takes the shared bus lock (`SPI.beginTransaction`, as the card does). DIO1's interrupt only wakes the task; no SPI in the ISR. **Done when** a Gemini page streams to the card while the Sniffer receives, with no lost packets and no card errors (`lora status` counters). |
|
||||
| Q94 | **Receive only:** the Radio Service has no transmit function in M3. It doesn't exist, rather than being unused. |
|
||||
| Q95 | Sniffer defaults: **EU868 LongFast**, 869.525 MHz, BW 250 kHz, SF 11, CR 4/5, sync word 0x2B, preamble 16 (Q19). The other Meshtastic presets are offered, plus custom settings. |
|
||||
| Q96 | The Sniffer lists packets (time, RSSI, SNR, frequency error, length; hex dump on Enter) **and decodes the Meshtastic header**: the first 16 bytes are never encrypted (destination, sender, packet ID, hop limit and hop start, channel hash, next hop, relay node). Host-tested. Payload decryption is M4. |
|
||||
| Q97 | A Sniffer **Capture** is pcap with **LoRaTap** headers (link type 270), for Wireshark. Started by hand, Status Bar mark, its own Clean-up category, the 90% rule. |
|
||||
| Q98 | **Sweep** steps across the Region's band (863–870 MHz) in 100 kHz steps by default, reading instant RSSI: bars with peak hold, and a waterfall, Wi-Fi Tools style. Optionally CAD on the preset's frequency to tell LoRa traffic from noise. |
|
||||
| Q99 | Sweep takes the radio and pauses the Sniffer, visibly (Q18). From M4 it pauses the Mesh Service the same way. |
|
||||
| Q100 | The Sniffer runs while the App is open **or a Capture is recording**; otherwise the radio sleeps. From M4 the Mesh Service keeps it on. |
|
||||
| Q101 | **Status Bar:** a radio mark while receiving, flashing on each packet; muted during a Sweep. |
|
||||
| Q102 | Debug aids: `lora status` (settings, counters, last RSSI/SNR, noise floor), `lora probe`, `lora rx on/off` (packets on the consoles). Raw packets are never written to the card outside a Capture. |
|
||||
| Q103 | A ring of the **last 32 packets** in RAM (about 9 KB at full length); older ones are dropped unless capturing. IRQ task stack trimmed by measurement; RadioLib's flash and RAM measured in step 1 against the floors. |
|
||||
| Q104 | **Done when** (below) includes an hour of listening on LongFast by a window. Real packets heard become M4 test fixtures. If none are heard, M3 still closes, and a reference Meshtastic node (Q21) becomes a requirement for M4. |
|
||||
|
||||
## Done when
|
||||
|
||||
- `lora probe` reports the SX1262, its oscillator setting and the RF switch arrangement, and the result is written here.
|
||||
- The Sniffer receives on LongFast with the App open or a Capture running, and the radio sleeps otherwise.
|
||||
- Sweep shows the noise floor across 863–870 MHz, and a known signal (a remote key fob, a 868 MHz sensor, anything) stands out. *Half met: the floor and the device's own steady peaks show; no known transmitter was tried.*
|
||||
- The shared-bus test passes (Q93): a Gemini page to the card while the Sniffer receives, no lost packets, no card errors.
|
||||
- A Capture opens in Wireshark with LoRaTap fields.
|
||||
- The Status Bar mark follows Q101.
|
||||
- One hour of LongFast listening by a window has been run and its result recorded here. *Run outside, on battery.*
|
||||
- Free heap stays above the floors (Q86) with the Sniffer, Wi-Fi, IRC on TLS and the UI running.
|
||||
- Nothing in the firmware can transmit.
|
||||
|
||||
## Work breakdown
|
||||
|
||||
1. **Hardware check:** RadioLib in the build, `lora probe` (Q91), flash and RAM cost measured.
|
||||
2. **Meshtastic header and LoRaTap** (host-tested): header parsing, presets and their radio settings, pcap/LoRaTap writing.

||||
3. **Radio Service:** receive on its own task behind the bus lock, the packet ring, `lora status` and `lora rx`, the shared-bus test.

# OTA — Firmware Updates over Wi-Fi and from the SD card
|
||||
|
||||
**Goal:** install new firmware without a USB cable. Push it from the PC over Wi-Fi, or drop it on the SD card. Unsigned images are refused, and a broken update rolls back by itself.
|
||||
|
||||
## Decisions (design round 2026-10-03)
|
||||
|
||||
| # | Decision |
|
||||
|---|---|
|
||||
| Q52 | Two sources: **push over Wi-Fi** from the PC, and **from the SD card**. Pulling from Gitea releases is deferred. |
|
||||
| Q53 | **Signed Update Files** (ECDSA P-256 over SHA-256). The private key stays in `~/.config/roro9stack/`, and the firmware embeds the public key (ADR 0003). |
|
||||
| Q54 | The device **always listens** for pushes on the LAN while Wi-Fi is Connected. *Revised in M2:* it was announced over mDNS as `roro9stack-<id>.local`; mDNS was removed to save RAM (it never crossed the dev box's routed network anyway). Pushes go to the IP shown in Settings → Firmware. |
|
||||
| Q55 | New firmware runs on **Probation**. It's confirmed once booted, UI drawn, Services started, 30 s without a crash, and Wi-Fi connected (if configured). Otherwise **Rollback**. A Toast reports either outcome. |
|
||||
| Q56 | **Downgrades are allowed**, with "older than the installed version" shown. |
|
||||
| Q57 | A valid push **installs right away**: progress screen, then reboot. The reboot waits for Text Entry to end, 60 s at most. |
|
||||
|
||||
## Done when
|
||||
|
||||
- `scripts/ota_keygen.sh` creates the key pair once. The public key is committed; the private key never is.
|
||||
- `scripts/flash.sh --ota` builds, signs and pushes to `roro9stack-<id>.local`. The device shows progress, reboots, and a Toast confirms the new version.
|
||||
- An Update File with a bad signature, a truncated or corrupted image, or no signature is refused, and the device keeps running.
|
||||
- Settings → About → **Update from SD** lists the `.ota` files in `/updates` and installs one.
|
||||
- A firmware that crashes during Probation rolls back to the previous version, and says so after the reboot.
|
||||
|
||||
## Work breakdown
|
||||
|
||||
1. **Update File format** (host-tested): header (magic, format, version, image size, SHA-256), signature, image. A streaming parser that hashes as it goes and decides accept / refuse / downgrade. The signature verifier sits behind an interface, so tests can inject one.
|
||||
2. **PC side:** key generation, `make_ota.py` (wraps `firmware.bin` into a signed `.ota`), and the push client. `flash.sh --ota` ties them together.
|
||||
3. **Device:** the Update Service.
|
||||
- A listener on TCP 3232 plus mDNS.
|
||||
- Writes the image to the inactive app slot, with the ECDSA check through mbedTLS.
|
||||
- A progress screen, and a reboot that waits out Text Entry.
|
||||
4. **Probation and Rollback:** the health checks, confirming the image, and detecting a rollback after reboot to report it.
|
||||
5. **Update from SD:** the same parser, fed from the Storage Service's task (all card access stays there).
