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.

Thank you, I have sent a PM with this information.

Thanks.

Those match with what is in our internal systems, so they should work. Could you try to add it again?

Make sure that the device is connected to nRF Cloud before you try to add it to your account (LED 3 and 4 should blink together).

Unfortunately I am getting this error:

Do I need to add a new device certificate?

 If the device blinks LED 3 and 4 together, I don't think it is a problem with the certificates.

Could you connect to the DK with the LTE Link Monitor application in nRF Connect for Desktop, and send me the log?

Just so we can be absolutely sure that the device is able to connect to nRF Cloud as it should.

I have also updated our cloud team about this problem, so hopefully, they will be able to tell us what is wrong.

Hi again.

According to our cloud team, you had somehow managed to create multiple sets of certificates for the device, with multiple HWIDs.

The cloud didn't handle this properly, which is the cause of your error.

The device and all its certificates has now been deleted from the cloud, so it should work now if you simply power the device back on.

Could you try to add your device to the cloud again?

We will modify the cloud so that it will handle this edge case in the future.

I just managed to connect the device now. Thank you for your great support in resolving this issue promptly.

Hi Didrik,
