The issue I was having was some task (I suspect lwip) gets messed up. Stopping the modem, trying to connect wifi, etc, all just locked up the async console. I think you had the same?
Re-winding this thread to the 'power simcom off' freezes the console aspect as distinct from the disabling the simcard issue. I had the module disconnect again this evening, though without a datalogger attached. Some more information about this state: The mux is up AT communication with the simcom works on channel 3 and logs the expected tx and rx The simcom is connected to the cellular network No log messages recording periodic communications with the simcom are being recorded The monotonic and park time counters are not advancing. Could the cause of this problem be that the timers have stopped? This could explain why the periodic interrogation of the simcom has stopped, and perhaps simcom power off has a spin wait or other loop waiting forever for the timer to advance? What is the best way to investigate the state of the timers and periodic execution? See attached for a transcript of this debugging session.
