LoRaMesher

2 96 8.1 C++

The LoRaMesher library implements a distance-vector routing protocol for communicating messages among LoRa nodes.

Project mention: Event driven / “event sourcing” framework approaches to C/C++ control flow | /r/FastLED | 2023-05-26

secondly, I have been wondering how to implement an abstraction layer between radio communication modules (MAC) like nrf24, wifi, RFM69, etc and the rest of the program. The project you linked to LoRaMesher explicitly was designed to do that so that's very helpful as well
