Help with LTE connection after loss of connection

We have noticed that several of our nRF9160 in production have problem with reconnecting to the LTE-M network after temporarily losing connection. We have tried reproducing this issue by deactivating the sim for about 10 seconds and then activating it again. After the default six retries it gives up and stop trying to reconnect to the network. the only way we can achieve a connection is if we do a sys_reboot() or a hard reboot with watchdog. Why is the reconnect attempts not enough? Why do we have to force a reboot? Attached are relevant logs.

  • Thank you.

    We have now set those config values, and we have managed to extract some more logs as well. We are getting a lot of "X messages dropped", but we hope these logs can tell us something more of value.

    Her we have the logs from 00:40 - 00:49 + first restart logs. This is a board that has around -105/-111 dBm:

  • Too much debug logs from lte_lc and at_monitor. Those hide most of the relevant stuff.

    All that you can see that it repeats a cycle of about 20 seconds.

    CSCON: 0 appears when connection has been idle for 5 seconds (depends on network). This is when the network releases the connection and starts idling.

    %XT3412 notification looks like the network would allow 24 hours of sleep between Tracking area updates.

    %CESQ is just a connection quality updates.

  • Which version of the nrf_modem library are you using/compiling with? (See https://github.com/nrfconnect/sdk-nrfxlib/blob/main/nrf_modem/doc/CHANGELOG.rst). I believe the versions are aligned with the nRF SDK version numbers.

    I am experiencing maybe similar problems with a very simple test program (performing ping and DNS in an endless loop with a few seconds’ delay in between) using the nrf_modem library versions 2.6.1 and 2.7.0. I tested with the nRF9160 (MFW 1.3.6) and nRF9161 (MFW 2.0.1). The nRF can enter a state, after a cell change, where it can send data, reports CEREG=5 and CSCON=1, but no data is delivered to the receiving socket or getAddressInfo; both simply timeout. This repeats indefinitely, with no chance of recovery other than switching to flight mode or performing similar hard resets.

    After downgrading the nrf_modem library to 2.5.0, the issues seem to have disappeared. Can you confirm this as well? Which version are you using?

  • Hi  ,

    We could probably investigate your problem further. I would recommend that you open a new ticket and provide all relevant information.

    Best regards,
    Dejan
