LTE NB - IOT (Telenet - Belgium)

  • Hi, i'm a newbee in using the Gpy, ... I want to connect to a mqtt broker via the NB-IOT.
    My provider is telenet ( APN : apn="")

    This is the error that i receive when i try to connect

    connecting [##] connected!
    Traceback (most recent call last):
    File "<stdin>", line 49, in <module>
    File "/flash/lib/", line 26, in init
    OSError: [Errno 202] EAI_FAIL

    The carrier is not listed is that the problem ( i used AT comment: "AT+SQNCTM=?" to see the listed carriers)?
    The mqtt broker works fine when i'm using wifi instead of lte.

    Someone that can help ? Thanks

  • @carl-declercq Best of luck, let me know if you need any further help!

  • @techykermit thanks for the quick reply: Yes I flashed the NB software in the Gpy , I only send the data once, but indeed maybe i must try several times (thanks, I will get back with some feedback)

  • How many times have you retried sending data? I sometimes get this error too, but lte.detach() and then a full reset of the device machine.reset() usually works.

    And the obvious - are you sure that NB-IOT is the flashed firmware on the LTE modem? If not, you have to flash it to the PyCom. This is what I would check first.
