IoT Base CATm - Core2 restarts every 3-5 min or so



  • Re: Core2 keeps rebooting with PoE base

    I’m guessing this is probably the same/similar issue I’m having with my Core2 and the IoT CATm base?

    What exactly do I need to do here? Please help :)



  • Hello @iamjameshannam

    the issue described in Core2 keeps rebooting with PoE base is an immediate reboot cycle within a couple of seconds (and not after a few minutes). So, no, I don't think this is the same issue.

    Can you describe what software you are running on your M5Core2? UiFlow? Arduino?

    Are you running from external power or battery?

    Thanks

  • Hello @iamjameshannam

    do you have a SIM card in your IoT Base CatM module?

    I did some testing and from within UiFlow it seems that as part of the module initialization (e.g. catmiot = module.get(module.CATMIOT)) an AT+CPIN? command is sent repeatedly (about every 6 seconds) until the module response is +CPIN: READY. Without SIM card the module response is ERROR which means the program flow is blocked forever.

    Thanks
