My board has been working for a while but I don't receive message on sigfox backend since a few days.
I enabled debugging to see if something is wrong.
status(ATMEL) always displays PA OFF. Don't remember what I had when the messages were received on the backend. I put some status(ATMEL) at differents places but always PA OFF. status(SIGFOX) is always OK
Could you tell what you get on your working boards?
