Is Gpy AT&T PTCRB certified?



  • Hello Pycom,

    I see that Gpy is Verizon certified.
    With the new firmwares, Gpy is working much much better.

    I saw in an earlier post that you may be working towards PTCRB for AT&T.
    Any update on that?

    Thanks



  • @pechan I used the CAT-M1 example code verbatim and it worked the first time through.

    https://docs.pycom.io/tutorials/lte/cat-m1.html

    import socket
    import ssl
    import time
    from network import LTE
    
    lte = LTE()         # instantiate the LTE object
    lte.attach()        # attach the cellular modem to a base station
    while not lte.isattached():
        time.sleep(0.25)
    lte.connect()       # start a data session and obtain an IP address
    while not lte.isconnected():
        time.sleep(0.25)
    
    s = socket.socket()
    s = ssl.wrap_socket(s)
    s.connect(socket.getaddrinfo('www.google.com', 443)[0][-1])
    s.send(b"GET / HTTP/1.0\r\n\r\n")
    print(s.recv(4096))
    s.close()
    
    lte.disconnect()
    lte.dettach()
    

    Make sure you have updated the modem to latest: https://docs.pycom.io/tutorials/lte/firmware.html

    I had to use a micro SD card to update the modem. I couldn't figure out how to upload the files into the internal flash, but that was probably something I was doing wrong.



  • @curtis-hendrix Could you share the code you used to connect to att with a hologram sim card?



  • I know this is old and I don't have an actual answer to the question. However, I have had good luck connecting to AT&T's network with the GPy using a SIM from AT&T and from Hologram. Will the GPy work AT&T? Probably? Is it AT&T certified? Who knows.
