I am trying to follow the instructions in the Command Interface Guide that say:
// Example for HL7588 AT&T modules using 4G with only 1 PDP context allowed, and
// where CID must be 1
I am setting up our modems to use the AirVantage system to allow for FOTA updates but am running into a problem with where each time I try to connect I get “Session with the server failed”:
But if I 1st run “AT+CGATT=0” and detach from the PS it works.
This is great but it causes all sorts of problems for the rest of my application. My data connection is no longer working and I have to turn off PDP, close my GPRS connection, turn back on the PS, turn on PDP, and reconnect to GPRS to get data working again.
BUT then Device Services stops working again and I have to go through the whole process again.
Below are my settings:
Is there a way to set Device Services up where I won’t have shut down the PS connection, perform Device Service Session, then re-attach to the data side of things?
PS: sorry if my working is not correct, I am slowly learning how all this fits together but still don’t fully understand. Thanks!
