RadioLib PingPong not working
-
I could need some help with LoRa communication between an T-Beam SoftRF SX1626 and a T-Beam Mashtastic. I tried to use the transmitter and receiver code from:
https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/examples/RadioLibExamplesbut this didn't work.
then i used the base of this code (utilities.h, LoRaBoards.h, LoRaBoards.cpp) and changed the main.ino to this:
