Hello, 

Thanks for reaching out, and sorry to hear about the issue. 

Are you working with the nRF9160 DK or Thingy:91? Have you programmed the latest version of the Asset Tracker, or the AT Client? Can you please take me through the steps you have followed?

Kind regards,
Øyvind

Hi,

I don't understand why the commands AT are not working for Data tests (Ping, Data HTTTP), the application are installed correctily and the Attach LTE-M under our network is OK, can you please check and help us the fix this issue

Thanks and Regards,

 You are currently running the Asset Tracker application which supports the AT Host, running a set of 3GPP standard commands. From the AT Command Reference Guide

"This document describes the AT commands used to control the modem in nRF91 Series devices. The nRF91 series AT command API enables modem control for firmware running in the application core on nRF91 series devices.

The AT command API can also be exposed on one of the nRF91 serial interfaces by programming appropriate firmware in the application core. The nRF Connect SDK contains examples of such proxy firmware that can be run stand-alone or as part of other firmware functionality in the nRF91 application core. The stand-alone example is called at_client. This way, an external MCU or computer can get access to the modem API either exclusively or in addition to application firmware running on the nRF91 itself.

The AT commands described in this document apply to all versions of the nRF9160 module hardware."

The nRF91 series AT commands do not support PING, data, HTTP.

The PING, DATA and HTTPCCON AT commands are available in the Serial LTE Modem application. This application sample uses a series of proprietary AT commands to let the nRF91 development kit operate as a Serial LTE Modem (SLM).

Please reprogram your device with the Serial LTE Modem or the Modem Shell.

If you are not able to do so, please reach out to your RSM.

Kind regards,

Hi,

Do you have video that shows how to configure the serial port?

Thanks and Regards,

Hi,

Please don't close this ticket, this issue is not fixed yet

the AT interfaces are working, i can use some command AT to control the modem but the commands AT for DATA and SMS are not working, we can organise session live to fix this issue?

Thanks and Regards,
