T-Mobile NB-IoT in the Netherlands?



  • Has anyone gotten T-Mobile NB-IoT in the Netherlands working on FiPy or GPy?

    I have updated my GPy to version 1.18.1.r7 and the LTE modem to version NB1-40343.



  • Hello @paul-thornton,

    It is failing to attach. Functions lte.imei() and lte.iccid() return sensible values. AT+CSQ returns 27,99.

    >>> import sqnsupgrade
    >>> sqnsupgrade.info()
    <<< Welcome to the SQN3330 firmware updater [1.2.1] >>> 
    >>> GPy with firmware version 1.20.0.rc4
    Your modem is in application mode. Here is the current version:
    UE6.0.0.0
    LR6.0.0.0-40343
    

    My test code:

    import os
    from network import LTE
    import time
    
    lte = None
    
    def get_LTE():
        global lte
        if lte == None:
            lte = LTE()
        if lte.isconnected():
            return True
        lte.attach(band=8, apn="cdp.iot.t-mobile.nl")
        attempts = 0
        while not lte.isattached():
            time.sleep(5)
            attempts = attempts + 1
            print('Attaching...', attempts)
        print('LTE attach succeeded!')
        lte.connect()
        attempts = 0
        while not lte.isconnected():
            time.sleep(5)
            attempts = attempts + 1
            print('Connecting...', attempts)
        print('LTE connection succeeded!')
        return True
    
    def end_LTE():
        global lte
        if lte == None:
            return
        print("Disonnecting LTE ... ")
        lte.disconnect()
        print("Detaching LTE ... ")
        lte.dettach()
        print("Shuttting down LTE...")
        lte.deinit()
        lte = None
    
    def test_LTE():
        os.uname()
        get_LTE()
        time.sleep(60)
        end_lte()
    
    if __name__ == "__main__":
        test_LTE()
    

    After more than an hour it is still not attached.

    The T-Mobile Netherlands IoT page only describes how to connect other platforms. (Link).

    What can I try next?

    Hey.

    What issue are you having? Is it failing to attach, or attaching but failing to make any external connections?
