Hello, I´m new to the nRF9160-DK board and trying to update the certificate. How can I get the modem from power off state in offline state?

I have the same problem as Henrik M. . I am in Germany. According to https://ibasis.com/solutions/iot-connectivity/network-coverage/ iBasis has limited coverage in Germany. Can you recommend a sim card from an other provider with good coverage in Germany?

I have an early nrf9160 (PCA10090 v 0.8.2).

I have updated the modem fw to the newest.

I have updated the certificate without problems.

I have built (via Segger) and installed the newest release version of the asset_tracker onto the board.

I register the SIM via nrfCloud, install the SIM, and turn on the device.

Now after 11 minutes, it still doesn't connect to the network (LTE).

Finally after around 13 minutes, this is output to the log, and the LTE icon turns solid gray (in the LTE Link Monitor app):

%CESQ: 29,1,17,2
+CEREG: 2,"26AC","00B14F8C",9
[00:12:09.635,650] [0m lte_lc.parse_nw_reg_status: Network registration status: 2 [0m
+CNEC_EMM: 15
[00:12:09.925,964] [1;31m lte_lc: Could not parse AT+CEREG response, error: -11
[0m[00:12:09.934,051] [1;31m lte_lc: Could not get network registration status[0m
+CEREG: 4,"26AC","00B14F8C",9
[00:12:09.944,763] [0m lte_lc.parse_nw_reg_status: Network registration status: 4[0m
%CESQ: 255,0,255,0
+CEREG: 4,"FFFE","FFFFFFFF",9
[00:12:09.993,286] [0m lte_lc.parse_nw_reg_status: Network registration status: 4[0m

Then after a bit longer, the LTE stays gray, but the signal strength indicator shows 3 out of 4, while the Current Band shows N/A.

The Chart shows some activity too. A green line appears showing reference signal power. But at the same time an event (in the chart) says "No suitable cells in tracking area".

I'm living in Denmark, where the iBasis website says there's national coverage.

What's going on? Thanks in advance.

I successfully downloaded and provisioned new certificates on my nRF9160-DK but I get this error message when trying to add it to my cloud account. "There was an error adding your device: Ownership code XXXXXXXXXXXX is invalid for device nrf-352656100218497."

I followed your instructions to update the nRF cloud certificate. After clicking the Update certificates button I receive the following error log:

Any suggestions, what went wrong?
