nRF9160 deactivating network auto connect possible when at+cfun=1 has been sent?

Peter

Dear All,

is it possible to configure the nRF9160 modem not to auto connect to a LTE network when at+cfun=1 is sent? I know that with at+cops a specific operator can be selcted but I was not able to keep the modem disconnected by default after power up with +cfun=1.

Thank you,

Peter

    Hi Peter,

    I think the key point here is not to disable the modem connection. What you need is to use %COPS to check all available PLMNs for both LTE-M and NB-IoT. The modem firmware does not have this middle state that the modem is ready for connection but actually not, which can scan available PLMNs.

    Could you check LTE-M and NB-IoT separately to achieve your target? I think this will be 100% getting all PLMNs under current modem fimware, but only a few additional steps on your application codes, which is easy to achieve.

    Best regards,

    Charlie
