I’m not able to join the Helium network using the example project that comes with the board libraries. I updated the DevEui, AppEui, and AppKey but it still won’t connect. I have other LoRaWAN devices / nodes that work so I know it’s not a reception issue. I used MSB (Big Endian) values for the DevEui and AppEui, and LSB (Little Endian) for the AppKey.
Is anyone able to see what I’m doing wrong? Thanks!
