Your documentation was using the tag v0.3.99, which is a newer SW than the one I am using. I noticed that in the v0.3.0 documentation, step 15 is missing. Most likely, you are running the v0.3.0 FW on your board & therefore you cannot send AT commands yet. I would wait until the stable v0.3.99 tag is released here.

Looking at the code difference between the at_client example & the asset_tracker example, it seems the at commands functionality from the at_client example (i.e. at_host_init() & at_host_process()) has not been added to the asset_tracker example. Therefore, it seems as of now that this step cannot be tested.

I followed your testing guideline "here" which is same as the link http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/asset_tracker/README.html#asset-tracker I posted in this question.

I can successfully completed from steps 1 thru 14 including connect to the nRFCloud

I also followed your instruction to connect to the Tera Term and LTE Link Monitor as the testing guideline suggested in step 2.

However, I don't know how to perform "step 15: Optionally send AT commands from the terminal, and observe that the reponse is received. " as suggested in the testing guideline. Please guide me if this step 15 can be tested. Thanks.

The asset tracker example does not include the AT module for sending & receiving AT commands. Could you please follow the testing guideline here? In step 6, you can use a tool such as tera term to see the logging of the nRF91 DK. Make sure to open up three terminal windows & connect to each of the three COM ports. In the example below, this would be COM 103, COM 104 & COM 105:

Are you able to connect to the nRF Cloud?
