Lora SX1278 connection to Seeeduino Xiao fails to start?

Products & Technology LoRa

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.

Hi did you try to connect a second DIO pin as far as i know the most LoRa libraries need 2 DIO pins.
I use the XIAO with an RFM95 SX1276 i use pins
SS => 1
dio0 => 2
dio1 => 3
RST not connected
I use the GitHub - mcci-catena/arduino-lmic: LoraWAN-MAC-in-C library, adapted to run under the Arduino environment library
