MTMC-Bridge
Relays the public channel between Meshtastic and MeshCore, Win & Linux
...It simultaneously manages MeshCore companions (connected via USB serial) and Meshtastic node (accessible via TCP/IP or USB serial), enabling bridging between networks operating on different bands or frequencies (for example, an 868 MHz companion, a 433 MHz companion, and two separate Meshtastic routers).
The bridge operates using full broadcasting: every active module retransmits messages to all the others.
Any module that is missing, disconnected, or unreachable simply attempts to reconnect in the background without blocking the others. The bridge becomes operational as soon as at least two modules are active.
