The MeshCore preset is the default for a new device, in the Settings and in the radio before the Scanner is opened. The setting now accepts it: it only took the 7 Meshtastic presets, so MeshCore picked in the App was not saved. Messages on MeshCore's public channel are decrypted with the channel's published key (AES-128, checked with 2 bytes of HMAC-SHA256): the row shows who says they sent it and the start of the text, the details the sender, the time and the whole text. Other channels and private messages stay encrypted. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0162FokPdvY2KsS4NBfwyWPk
