Fair enough, I did quite a bit of reading on TTN about Gateways, Nodes, Applications, etc... I think once I can muster up some more funds for an actual Gateway; I will convert this to a Node. This PyCom LoPy4 is really a learning experience for me. The idea of using MicroPython is all new to me. Cheers,

@maelstrom Hello, LoRaRAW works for me between 2 LoPys both on EUR and US frequencies on the latest firmware, all the other parameters are default values.
