I’ve been trying to connect my SX1278 to my Seeeduino Xiao as it already works with my Arduino Nano for this tutorial: https://how2electronics.com/interfacing-sx1278-lora-module-with-arduino/
However connecting all the cables correctly still results in “Starting LoRa failed!” and I think it’s because the XIAO lacks a CS pin. I’ve tried manually assigning the pin to pin 1 and 4 but neither have worked. Am I missing something obvious here?
Edit: I’ve since used
#define ss 4
#define rst 1
#define dio0 2
and LoRa.setPins(ss, rst, dio0);
This allowed me to get it working exactly once, now it won’t work again giving the failed message. Very confusing.
