No problem at all :) Let us know if there is anything else!

Hi Elfving ,

To my embarrassment I must confess that the build I was testing was missing

CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y

CONFIG_MODEM_JWT=y

which are of course necessary for preconnect-onboarding. With a corrected build the device registers with the cloud as expected.

Thanks and sorry for the noise ;-)

Could you try your first approach again and run device_credential_installer with -d, this will replace what ever you have in the sectag and place the new one. Basically the next steps:

create_ca_cert

device_credentials_installer -d --ca *_ca.pem --ca-key *_prv.pem -d --verify

nrf_cloud_onboard --api-key $API_KEY --csv onboard.csv

This is similar from what is written here. Also confirm that you have these Kconfigs in yout project, either in .proj or in some overlay:

# Enable modem-based JSON Web Token (JWT) generation required for nRF Cloud authentication
CONFIG_MODEM_JWT=y

# Configure the nRF Cloud library to use the device's internal UUID as the client ID
CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y

# Define the modem security tag where nRF Cloud credentials will be stored (16842753 is the standard tag used by Nordic examples)
CONFIG_NRF_CLOUD_SEC_TAG=16842753

Hi Terrence,

I'll ask the relevant R&D team. I'll let you know once I hear from them.
