ERROR: Problem in adding the new nRF9160 DK (PCA10090) device in nRF Cloud

[Dheeraj]

Hi, 

I have a Thingy91 (PCA20035) device added to my nRF cloud account and accessing without issues. 

But today I have got a new nRF9160 DK (PCA10090) along with a new SIM etc,

I can verify the SIM without issue, but facing issues while adding it to the "Add  LTE Device". 

ERROR: "There was an error adding your device. You might be trying to upgrade an older nRF91 development kit. Unless you update your device, you will have to click the "Have an old devkit without a PIN?" Link Below ". 

Please find the same in the screenshot attached and help me to add the new nRf9160 DK (PCA10090) to my nRF cloud account. 

Thank you.

Hi again!

I can see from GSMA's deployment map that neither LTE-M nor NB-IoT has been deployed in your country, which is why your device can't get an LTE connection and is restarting. 

Best regards,

Hi, 

Actually, nRF9160 DK (10090) is in USA (California). I am remotely working on it. 

Note that, I am also working on Thnigy91 (PCA20035), where I do NOT have any issues. 

I am able to successfully build and flash (mcumgr) without any issues on Thingy91 (PCA20035).

Since we have issues to flash nRF52840 (PCA20035), we have bought a new nRF9160 DK (10090), which unfortunately

NOT working.

I have tried all possible ways to get it back, but no luck. it is continuously rebooting.   

Followed "  https://devzone.nordicsemi.com/f/nordic-q-a/54272/issue-nrf9160-dk-pca10090-is-rebooting  " 

Please help me with this issue, as its blocking my development activity. 

Thank you.

Could you try the things I suggested in my previous reply?

Running through the tutorial you linked to and then adding the device to nRF Cloud. And attaching a screenshot of the error message if it doesn't work.

Hi Heidi, 

I have followed the steps mentioned in the link  [ https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/nrf-cloud-certificate-update  ] above. 

Due to the continuous rebooting device (nRF9160_pca10090 DK), NOT able to execute the AT+CFUN=4 command. 

I have tried flashing the "nrf9160dk_at_client_09-10-2019_c9c833b1.hex", but no luck. 

Eventually, updating the certificate on the nRF9160 (PCA10090) board is  FAILED and NOT able to add to the Cloud account and still rebooting. 

Please find the screenshot attached and do needful. 

Thank you.

Ok, so just to clarify, even though you successfully flashed the at_client sample to the device, you could not set the modem in offline mode (AT+CFUN=4) because the device keeps continuously rebooting. 

This happened to my device once and what worked was updating the modem firmware (even if you are using the correct version). 

I see from your other posts that you are trying to program the Thingy:91. Note that the nRF9160 on the nRF91DK does not have to be functioning for you to use the nRF91DK as a debugger to program the Thingy:91.

Best regards,

Heidi

Correct.

Here, I have tried to update the mode firmware on nRF9160 DK (10090) device, but I am getting the following errors. 

nrfjprog --eraseall -f nrf91

nrfjprog --program firmware.update.image.segments.1.hex --sectorerase -r -f nrf91 --verify Parsing hex file.
ERROR: The file specified is not a valid hex file, has data outside valid areas
ERROR: or does not have data invalid areas.

(Same issue was observed while flashing with nRF Connect v3.2.0)

I have downloaded modem firmware from " https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF9160-DK/Download#infotabs "

(mfw_nrf9160_1.0.1 -->firmware.update.image.segments.1.hex & firmware.update.image.segments.0.hex)

If I am wrong, pl let me know the correct modem firmware Image.

Just for your information: I did NOT connect thingy91 (PCA20035) to nRF9160 DK (10090) device, as DK (10090) itself NOT stable yet. I am NOT trying to flash thingy91 (PCA20035) using nRF91 DK (10090) for now. 

After all, now I am able to see the new ERROR Message while adding nRF9160 (10090) to the cloud account. 

Please find the screenshot attached. 

Thank you.
