I'm trying to use an Adafruit Feather 32u4 with LoRaWAN to send data to TTN. I tried 3 different libraries and I tried altering the code for region configuration. I'm from Europe, so I should use the 868MHz band. I tried 3 different antennae. The Feather's serial output looks like it's sending the data successfully, but the data doesn't show up on the TTN console. I've also tried testing it about a 100m far from a TTN gateway, didn't work either.
I know I should test it with 2 boards directly at first but I don't have 2 boards and I don't have the time and money to get them now. I'm trying to solve the issue here too.
Any ideas? Thanks.
