Unable to add LTE Device on nRF Cloud

Moroccha

The nRF9160 DK I'm working on does not seem to be able to connect to nRF Cloud after following the tutorial:

https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF9160-DK/GetStarted

LED 3 continues to blink but LED 4 does not light up, indicating that it cannot connect to LTE. Actually, when i first booted up the nRF9160, it was able to connect to nRF Cloud, but once I checked the device page, it disconnected and could not connect since.

After looking at the tech support forums, I have upgraded the modem firmware via PC tool nRF Connect for Desktop to v1.0.1 

Afterwards, I built the Asset tracker sample by following the getting started assistant in nRF_Connect for Desktop (installing the toolchain, cloning the nRF SDK, Downloading the SEGGER Embedded Studio, and building the asset tracker application and downloading(flashing?) it with Target -> Zephyr/merged.hex

However, LED 4 still does not blink

Here are screenshots of LTE link monitor

And here are screenshots of the programmer

How should I resolve this? So that I can connect to nRF Cloud? Thanks for your help

    Hi.

    Can you try to flash this: asset_tracker.hex

    And then provide me with logs when you run it?

    Best regards,

    Andreas

    Hi, I attached the log file from LTE Link monitor after flashing the hex file:

    Hi.
    

    Could you turn of "Automatic Requests", turn on LLM and push the reset button on the nRF91 DK so that you get the correct bootup?
    

    So that you only provide me with the "log text that is blue"?
    

    Best regards,
    

    Andreas

    Hi.
    

    Can you try to flash this hex file instead: It has logging enabled, and please post the result and a screenshot as well would be nice.
    

    

    asset_with_log.hex
