Attach to NB-IoT network



  • Hi,

    As I am trying to attach the BC66-T-BE DVK to the NB-IoT network, the device doesn’t get an IP assigned. Here is some debug output, that shows, that the setup is ok so far, but AT+CEREG? goes from “trying to attach or searching” to " Not registered" after about 10 seconds. Setup was successful and no errors while reading the IMEI. Any suggestions? Location is east Germany.

  • Update:
    The SIM Card was not activated. Now I was able to connect to the Network.
    But now, as others mentioned, I cant get the ‘last payload’ in the GUI. I will wait for an update in other posts.

    Sorry, I missed this post.

    Showing the payload in our GUI is not a problem for new devices.

    What you need to do is the following:

    APN cdp.iot.t-mobile.nl
    Send your payload to: 172.27.131.100
