Hi everyone, I have a problem with the ubeCell Dev-Board HTCC-AB01, I cannot transmit data on the TTN and on the Helium network, I don’t understand where I am wrong, I am attaching the code:
The netmode used is OTAA.

In the TTN console I don’t see any join message while in Helium I only see many Join request and Join Accept messages. In the serial monitor I see that it stops in the join phase giving me an error after a few minutes. I ask you for help, I am quite frustrated. Thank you
