Unable to add LTE Device on nRF Cloud

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:
