https_client: at_host: Error while processing AT command: -1

[Rodrigo Aznar]

Hello,

I had to build the https_client sample again to compare some behaviors on my application and as I flash it to nRF9160 I am having a cyclical error as below:

 <err> at_host: Error while processing AT command: -1

I have chosen as configuration (using VSCode extension): 

board:  nrf9160dk_nrf9160_ns

Configuration: prj.conf

Use sysbuild [x]

toolchain:  v2.7.0

west workspace: v2.6.1

The curious is that the exact configuration built in the same environment some days ago ran perfectly on the same target (with SIM card).

Does anyone ever faced a similar problem?

Hi,

It seems it is not able to connect to LTE.   

Can you please program the AT client sample  and use the cellular monitor to collect a modem trace? This way we can confirm an issue with e.g. SIM card or LTE network. The Cellular Monitor has a button to "refresh dashboard" which sends several AT commands. Please provide the output from the Serial Terminal (also available in Cellular Monitor) or another serial terminal that works for you.

Thank you!

Kind regards,
Øyvind
