Introduction

The LoRaMesher library implements a distance-vector routing protocol for communicating messages among LoRa nodes. For the interaction with the LoRa radio chip, we leverage RadioLib, a versatile communication library which supports the SX127X LoRa series module available on the hardware we used, among others.

Dependencies

You can check library.json for more details. Basically, we use a modded version of RadioLib that supports class methods as callbacks and FreeRTOS for scheduling maintenance tasks.

Currently Supported Protocols

  • Finding nodes using a simple routing protocol
  • Send messages broadcast or to one of the nodes in the routing table
  • Send reliable messages. It is accomplish sending ACK and other configuration packets inside LoRaMesher
  • Send large payloads. Since we cannot send packets larger than 222 bytes, we divide the payload and send reliable messages until is all sent/received
