nRF9160 nRF Cloud Connection Error (-111)

[Akshay]

Hello Sir,

I have a PCA10090 (nRF9160) DevKit and it was working fine with Asset Tracker Example. Kit sent data to nRF Cloud last month. Today i have again verify the same but today Kit cannot establish connection with nRF Cloud with the same Asset Tracker Sample Example provided in nRF Connect SDK.

When Kit tries to establish connection with nRF Cloud it provides error "-111".

I have also attached image from nRF Cloud.

Can you please guide us to resolve this issue?

Thanks,

Akshay

Hello,

When Kit tries to establish connection with nRF Cloud it provides error "-111".

This error code means connection refused. 

Can you please load and run the AT_Client example? This will give us a pointer to what is wrong, and see if the board connects to the base station. Please copy the output from LTE Link Monitor, and give me a screenshot of the window.

Best regards,
Oeyvind

Hello Oyvind,

I am getting the same error "nrf_cloud_connect failed: -111".  I had the asset tracker application fully working.  I was attempting the lte sensor gateway example so I did the secure boot example and it loaded ok.  After that I started working on the bluetooth part of that example but I noticed the led's didn't look the same.  Then I wanted to get back to the asset tracker example working and it just gives that error and restart's over again.  Any suggestions what to do next?  I loaded the AT example and it seems to work but if I go back to the asset tracker it still doesn't work.

OK, so I answered my own question in this case.  This was because instead of building with the 52840 "board" I was building with my 9160 "board".  That is what you have to change when you are doing the "Open nRF connect SDK Project".  Hope this helps someone else.

Yes, remember to check that SW5 is set to the correct device when programming. Did this fix the asset tracker and failed connection error at your point?
