Pysense+FIPY getting the error "Modem not attached"



  • Pysense+FIPY getting the error "Modem not attached" I did the steps mentioned for the firmware upgrade: https://docs.pycom.io/tutorials/lte/firmware/ and upgraded to the latest version.
    <<< Welcome to the SQN3330 firmware updater [1.2.5] >>>

    FiPy with firmware version 1.18.2.r7

    However when I try the following

    from network import LTE
    lte = LTE()
    lte.attach()
    lte.connect()
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    OSError: modem not attached
