  • Hi,
    by REPL console, sending just:

    from network import LTE
    lte = LTE()

    cause the reboot of FiPy.

    I have two Fipy’s one installed on a Pytrack board and another on an Expansion Board 2.0. I did a firmware upgrade on the the first Fipy on Expansion 2.0, the whole process never worked and went into safe recovery after multiple tries( with AT+SMSWBOOT=3,0, failed error). Now I have an
    error code for at command ‘ATI’ on that FIPY.
    So I have refrained from firmware update on the other FiPy on Pytrack . Now on the FiPy on Pytrack which was not updated ( firmware) it is still responding to lte=LTE(), followed by LTE(‘ATI’), but I get AT+CSQ as 99,99. And on the same FiPy if I do AT+ CGSN, I can get the modem IMEI number but AT+ CCID it does not return the SIM number. It makes me conclude that the SIM and the modem is not talking to each other or exchanging data. Should the system not respond to standard AT command even without firmware upgrade???
    My fiest FIPy is already not usable but I don’t want to do the same to the other.
    I am using two Cat-M1 SIM from Verizon and per one of the suggestions from @jmarcelino , I have already setup a ticket with you tech team.
    Hope to find a resolution soon! Thank you much for the assistance.

  • Hi Livius,
