Emnify using NB-IOT in UK



  • Hey guys,

    I need help starting with gpy and NB-IOT. I have a simcard from EMnify they are NB-IOT capable, but I have problems running an example. the example bellow is not attaching.

    import pycom
    import time
    from network import LTE

    Disable Heartbeat

    pycom.heartbeat(False)
    pycom.rgbled(0x0)

    lte = LTE()
    lte.init()

    lte.send_at_cmd('AT+CFUN=0') # disable modem
    lte.send_at_cmd('AT!="clearscanconfig"') # clear scanned frequencies
    lte.send_at_cmd('AT!="addscanfreq band=20 dl-earfcn=6300"') # set scanned frequency
    lte.send_at_cmd('AT+CGDCONT=1,"IP","em"') # set APN (Access Point Name)
    lte.send_at_cmd('AT+COPS=?') # scan available networks
    lte.send_at_cmd('AT+CFUN=1') # enable modem

    lte.attach()

    print("attaching:", end="")
    while not lte.isattached():
    print("", end=".")
    pass
    ā€‹
    print("connecting:")
    lte.connect()
    while not lte.isconnected():
    print("", end=".")
    pass
