nRF9160-DK LTE Link Monitor, no respons

[Mr Gu]

Hi all,

I have tried to follow the step to get up and running with my new nRF9160-DK, however, I am not sure if the Application FW has been successfully updated (how would you know?). I afterward tried to update the application modem (successful). But, once I try to follow the step to Provisioning the nRF Connect for Cloud certificate using LTE Link Monitor, the device is not responding. I tried pushing the RESET button but nothing happens. What could be wrong? Any ideas?

All the best,

Gu

Hello Mr. Gu, 

Looks like you are not programming the correct image to you device. Please use img_app_bl/nrf9160dk_asset_tracker_ltem_2021-03-01_8e8c6089.hex 

Let me know how that works for you.

Kind regards,
Øyvind

Øyvind,

Thanks a lot. That sure did it.

I am a bit confused, in the "CONTENTS.txt" file, it says the img_app_bl folder should only be used with debug probe? I am new to this, but I found this step a bit confusing :) 

 

All the best,
Gu

Mr. Gu, 

I agree, it is a little confusing. I will forward to the team who generates these files and have them make it more clear

Kind regards,
Øyvind
