A bidirectional bridge connecting Bitchat and Meshtastic networks allows local Bluetooth chat clients to communicate over long distances using LoRa radios. The system runs on a Linux-based device that relays messages between mobile devices via Bluetooth and the mesh network through a USB connection.
- Relays text from nearby Bitchat apps to the Meshtastic LoRa network.
- Broadcasts incoming LoRa signals back to all connected Bluetooth clients.
- Designed for Linux environments like Raspberry Pi using Python 3.7 or higher.
Bridge mode means that the "modem" doesn't do any Level 3 processing on the traffic and passes it through, sort of like an Ethernet switch, e.g. you wouldn't see a HOP in traceroute. With the AT&T Gateway you cannot achieve a true bridge mode. The best you can do is:
For a static public subnet: the Cascaded Router (if you want to use a router to manage the public subnet)
For the dynamic public subnet: IP Passthrough (or DMZplus on the Gateways that call the feature by that name).
