MODEM_EVT_ERROR causes a boot loop when the SIM card is missing

Alpo Leinonen

I am testing the Asset_tracker_v2 application on thingy-91. I took the SIM card out so the device goes into the boot loop.

The on_state_init () function has the condition MODEM_EVT_ERROR which happens here. As a result, a reboot is performed.

The question is how do I know that now the SIM card is missing?

Can I check based on sim-id (iccid)? That is zero in this situation.

Best Regards

    Hello Alpo,

    The question is how do I know that now the SIM card is missing?

    I’m not sure if I understand your question and use case.

    Since you removed the SIM card and as a result, Asset Tracker v2 sends a reset request, you should be aware of that your device doesn’t operate with a SIM card at that time?

    Regards,

    Markus

    Hi, I wish to tag a long for this. Sometimes my sensors won't have signal and will require separate code to be run. Is there anyway to check if the sim card is inserted or not? This would provide a nice way of telling what mode should be run. If not, is there a way to check for connectivity and then decide?

    Regards
