README

        
Warning this is a WIP, only a few hours of work has been put into it. Code was ported from multiple sources, it is messy and needs to be cleaned up. Basic rx and tx does work for LoRa but more testing is needed. FSK has not been added yet.

SX126x component configures SX1261, SX1262 or SX1268 hardware for use in ESPHome. Tested with the Heltec WiFi LoRa 32 V3 Dev-board with SX1262.

To use this repo (example for Heltec V3):
