It pains me to mention this but I don't think it's responsible not to: https://github.com/meshtastic/firmware/issues/4030 At time of writing (2025-09-27, plus or minus a timezone), there does not appear to be any serious attempt to secure application-layer message contents. (At least, not yet) My hope is that this cool new radio link option will still gain traction and grow and develop without painting itself into a corner, security-wise. To wit- security hints on https://en.wikipedia.org/wiki/OSI_model have improved substantially since my last readthrough.
In Meshtastic 64 – A meshtastic radio for the Commodore 64
Meshtastic is another project that has recently made serious strides[0] in their UX on the Lilygo T-deck (and similar ESP32 devices), but specifically regarding LoRA-enabled devices. It's still on a branch, but I compiled and ran it, and now I have two T-decks that can communicate with eachother off-the-grid without a smartphone attached to send messages; it's actually usable in emergencies now, which is why I bought the devices in the first place. Currently in the process to deploy a mesh from me to my parents and family. [0]: https://github.com/meshtastic/firmware/pull/3259
