SIM 7020E no IP Adress

Aron1317

Hello all.
I am trying to connect to the internet with the SIM 7020E. I use an IoT sim card for this. I managed to establish an APN connection, but unfortunately don’t get an IP address. Can someone tell me how to continue the code?

```

Serial.println(“********* Init Connection START ***********”);

toggleEchoMode(false, true);

runCommand("AT+COPS=?", "Operator Selection");
runCommand("AT+CGDCONT=?", "APN Selection");
runCommand("AT+CGDCONT=1,\"IPV4V6\",\"internet.m2mportal.de\"", "Set the APN internet.m2mportal.de for your carrier");
runCommand("AT+IPCONFIG", "Show IP Config");
runCommand("AT+CGPADDR=?", "Get the IP address assigned by the carrier");

Here ist the Reply i get:

I would be very thankful for your help!

Hello @Aron1317

have you tried to run the following command?

AT+COPS?

Note: no = sign.
This should tell you the current mode and the currently selected operator.
Also for my SIM7020G I use the following command to set the APN:

AT*MCGDEFCONT="IP","<APN>"

Note: * instead of + after the AT.

Thanks
Felix
