nrf9160dk - There was an error adding your device: nRFCode 40102

[OCMAD]

When adding the DK to my nRF cloud account, I get the following error message: "There was an error adding your device: nRFCode 40102: Ownership code [HWID] is invalid for device [DEVICE ID]." . I have tried using the old devkit method of connecting the device by carrying out the sequence of switch and button inputs, however this also does not work.

I am running the DK with 'nrf9160dk_asset_tracker_ltem_2020-04-29_bc7ade8b' firmware, and the 'mfwnrf9160120' modem. I have updated the device's certificate which was generated in my nRF account, using the certificate manager in LTE Link Monitor.

The device has LED3 and LED4 blinking together. When I test in LTE Link Monitor, the device connects fine, albeit with 1 bar of signal.

Thanks for your help.

Hi.

Did you enter the device ID on the form "nrf-<IMEI>", or just <IMEI>?

The device ID of nRF9160DKs and Thingy:91s must be on the form "nrf-<IMEI>".

Best regards,

Didrik

Hi Didrik,

Many thanks for the fast response. The device ID was entered in the form of 'nrf-<IMEI>' and I have tried entering the PIN/HWID with and without colons.

Did you follow this guide when creating the new certificates?

There is a missing step in that guide. You also have to "Reset your device". You can do that from the Account page on nRF Cloud, in the "Reset a Device" panel.

Could you try to reset your device, and see if that helps?

If not, I would like to see the log the DK sends over UART to the PC for further debugging.

Yes, I did use that guide. I have tried to reset the device inside of the account section of of nRF cloud however I receive this error:

I should mention that when I first received the DK, I was able to successfully pair the device to my nRF Cloud account. I decided to delete the device from my account when I updated the DK's firmware. And since then, I have not been able to add the device back my nRF Cloud account.
