Hi, and sorry for missing one important detail. You will need to program the Asset Tracker application in order for the device to provision

Hi,

I updated the certificate on the device successfully, then I erase the device from the nRFcloud. However, upon provisioning new LTE device I get Troubleshoot nRF Code 40412.

There was an error adding your device: No device found for this id. The device has not yet been provisioned. Troubleshoot nRF Code 40412

To add a device to your account, enter the device ID and PIN or HWID. For Nordic hardware like the nRF91DK or Thingy:91, the device ID is "nrf-" followed by the 15 digit IMEI. Example: "nrf-123456789012345"

It no longer is able to find this device id. LTE link monitor still yield -77 error.

Hi Jason,

My apologies for the late reply.

From the Account menu, did you also update your certificates?

This process is still being improved, however, you will need to update the certificates and then delete the device from nRF Cloud interface. Afterwards you can ensure that certificates are updated and re-register your device to nRF Cloud.

Let me know how this works for you

Kind regards,
Øyvind

Have you been able to get any more answers internally?

I have done the certificates and authentication as below:

To generate an evaluation token in the portal:

Log in to the nrf Cloud portal.
Click the drop-down menu in the top right corner.
Click Account.
Under REST API Authentication Management, find Service Evaluation Token.
Click Generate Token. A window opens asking for confirmation.
Click OK to generate the token.
The token appears in the text field to the left of the Generate Token button. You can copy and paste it using your mouse or keyboard, or copy it by clicking the clipboard button next to the text field. The token no longer appears once it has expired.

My token is still active on nrfcloud, so not sure what else could be causing the issue.

Thanks,
Jason Jantzi

Hello,

And thank you for reporting this. Yes, a full log output and modem trace would be very good. I have forwarded this internally, and will get back to you when I have more answers.

Edit: Can you please verify that you authentication / certificates are correct? "403 Forbidden" is often an indication that there is an issue with these. Please see the nRF Cloud documentation on Location Services

Kind regards,
Øyvind
