Thank you for your advice, but i do it, and i know for sure that it is the radio.Send(GATEWAYID, payload, sendSize+1, requestACK); function that make my sketch stop running. As I said, if I simply comment it, nothing is send but the sketch continue running. The sketc stop running precisely at this function if I don’t comment it.
I don’t know how to debug it more deeper, maybe going into the lib and test step by step, but I assume that your code is tested and must work, so maybe more an hardware or a power supply problem. I will continue when I got time to make some test, maybe with an independent power supply. If I found the solution, I will tell.
Thanks
