/dev/ has Debug Builds and the Debug Console (builds and the token, the console and its protocol, files and screenshots, driving the UI, crashes and Safe Mode, the command reference), Build, test and release (including how an update works), the architecture decisions and the milestone plans. Generated from the repository by site/tools/gen_dev_docs.py: the ADRs, the milestones, the README's sections, and the command reference, read from the firmware's own `help` text. The pages are committed (Zola cannot read outside its folder); the Site workflow checks they are current, and now also runs when src/main.cpp changes. M0, M1 and CONTEXT.md are not published. README: the gnss commands that the table lacked. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT

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.
