nRF9160 AT_client not working

[Mohammad Amin]

Hi,

I received my nRF9160 development board a week ago and tried to program it using the following guide:

https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/getting-started-with-nrf9160-dk?utm_campaign=1212+nRF91+launch&utm_source=facebook&utm_medium=social&utm_content=nRF9160+DK+getting+started+DevZone+blog

However, I have not any success. 

First of all, the guide is not compatible with the new SDK and there is no secure_boot app in the samples. But I think the "spm" project is its replacement. I programmed and ran the spm with "nrf9160_pca10090" as the board name and then ran at_client with "nrf9160_pca10090ns" as the board name. However, whenever I try to run an AT command using LTE Link monitor I get: Error: 'AT ' timed out. I tried to reset the board several times as in "https://devzone.nordicsemi.com/f/nordic-q-a/43180/nrf9160-dk-stopped-responding-to-at-commands/168837#168837" is suggesdted but it still is not working. 

Secondly, I tried to program "asset_tracker" which is in the application folder to the board but it does not work at all. I do not have any output at the LTE link monitor and no LED is blinking. Can please someone help me to program the board properly? Is there any other setting to be set?

Hello, please follow the steps in the "Getting Started Assistant" guide on the nrf connect for desktop application. You can install it from "Add/remove apps".

I have followed this guide: https://devzone.nordicsemi.com/f/nordic-q-a/45543/issue-with-command-line-compilation-of-nrf9160-samples/181310 and using "west build" I finally could compile the asset_tracker application. However, the board does not get connected to the network. I used iBasis, Hologram, Twilio sim cards and they all remain in LTE searching process when I monitor them in LTE Link Monitor. I live in Canada, Alberta state and I was wondering why the board is not getting connected to the network. My colleague in Toronto got connected once using iBasis, however, he reports the module is unreliable and 1 out of 10 it gets connected to the network.
