NRF9160 DK fails to reconnect to network

An update:

- last week I got the new O2 sim card ( for IoT ) and took the set up I had on site and brought it on the bench ( nrf52840 dk communicating over uart to nrf9160 dk ) . Did not change anything on it except for the sim card.

- I am now into the 5th day of the system running continuously without issues.

A next step would be to get the same set up with O2 sim card on site and see how it behaves in that area or put the O2 sim card into another set up like this ( just different devices ) on the bench. I will do one of them this week and let you know again what happened.

All the best,

Robert.

This post describes the procedure quite well. If you are unsure how to do it, make sure to follow every step carefully.

Hello, Hakon!

Please provide some guidance, a weblink, so I can set the logs for modem trace. Is it possible to monitor the dk that I have on site, since that will have valuable information? I am asking this because so far I had the monitored dk connected to my PC and the one on site is on battery.

All the best,

Robert.

Hello,

I can see from your other case that a lot has been tried already. The next thing you can try is capture a modem trace from the disconnect, and then I can pass it on for analysis.
