Not connecting to nRFCloud

Yano

Hi, we have an nRF9160DK (0.8.3) and it does not connect to the nrfcloud.

We have updated to the latest firmware 1.0.0

We only have nb-iot here so we  didn't use the iBasis sim, instead using a vodafone V-Sim (which is active). 

Are we missing a step here?

Thanks

    Hi Ian,

    The "Mobile Country Code" (MCC) and the "Mobile Network Codes" (MNC) can be found at https://www.mcc-mnc.com/ or directly from your operator.

    example:

    Ireland + Vodafone

    (AT+COPS=1,2,"27201")

    I would recommend testing with the at_client first since it's faster to do some quick changes in the settings to the modem while you try to connect to the network.

    In that way, you can confirm that you can get an attachment with the base station and a connection with the network.

    so when you get a connection with at_client you know what is needed to get a connection with the network and can then implement this in the other applications as "asset_tracker".

    AT+COPS? will search through all the bands and that will take some time, so it is expected to get a timeout when trying to send AT-commands while the modem is in this searching mode.

    So you should not need to press that button. 

    Please try with the MCC/MNC codes and share the LTE Link Monitor log.

    Best Regards,

    Martin L.

    Morning Martin,

    No luck, below is the list.

    BTW should is it OK to have the asset_tracker running in the background while I'm using the at_client (i.e. should I erase everything and load inn your hex file)?

    Also could it be an issue with our V-Sim? As far as I know its OK (account etc.) but we have never tested it with any other hardware.

    Thanks

    Ian
