Is Gpy AT&T PTCRB certified?
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?
@pechan I used the CAT-M1 example code verbatim and it worked the first time through.
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)[-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.
