Good morning
I created my application with the correct dev eui and
but after the following instruction:
int ret = modem.joinOTAA(appEui, appKey);
Have you ever received rets of 0, meaning the connection is not being made?
if then, I force the sending of messages, they sometimes arrive, so I deduce that the connection must be established, but never ever do I get confirmation of connection
Do you know where the problem could come from, if ever?
thanks in advance
