I am currently in the process of integrating the cellular LTE modem into a weather measurement sensor. Because these are intended as "mission critical" sensors, I am looking for a solution to auto-restarting the XBee if the code crashes. I have seen this happen a few times with the Micro Python script that I am running. Is there built in to the module a watchdog timer that I could activate and then reset from my Python script? Im sure there is a way with additional hardware that I could pull the reset line, but I am hoping for a simpler solution.
