I'm new to AVR Freaks forums and I'm sorry that my first post isn't something more constructive than a question.
Any help with this problem would be greatly appreciated.
I have two Arduino Mega boards sending weather information to my server. I noticed that in the low GPRS signal areas (60% and less) my Arduino will freeze when the SIM800L GPRS module turns on to send data (it turns on via n-channel mosfet).
I have solved this problem by making an external watchdog circuit so it restarts the whole thing if this happens but I don't see this as a solution. The one with 95% signal restarts once every 24 hours as it should, but the one with 45% signal restarts about 4-5 times a day.
So I was wondering if anyone else encountered this problem and if I could get some hints on solving this issue.
Thank you and best regards!
