<![CDATA[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 :)

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
Felix

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
