Your own private radio network.
Atlas Relay is an off-grid text network. Pocket handhelds pair to LoRa relays over Bluetooth and talk on a private, encrypted channel, with no towers, no internet, no accounts. Place a relay up high and it repeats for everyone.
Private by design
One encrypted "Atlas" channel on its own frequency slot, off the public mesh. Discovery is instant and everyone agrees on who's online.
Neighbourhood + DMs
A shared broadcast room plus 1:1 private chats, with unread badges and 24-hour history that replays when you reconnect.
HQ news ticker
Bulletins from HQ scroll across every unit as a live news crawl, network-wide announcements with no setup.
Characterful relays
Each relay has an animated face, a packet-processing LED flicker, and an optional chirp. Named like vehicles, unique per device.
Real range
Hundreds of metres in the city, many kilometres with height and line-of-sight. Extra relays repeat automatically to blanket an area.

firmware-….bin, which is app-only / OTA). Rename it to e.g. atlas_relay_v1.2.46.bin if you like. Hosting it at a fixed URL later enables one-click installs. The relay firmware is a Meshtastic (GPLv3) build with the Atlas additions.Web Console
