Is there any step by step instruction for onboarding process ?

[FlashBack123]

So, I have built prototype boards using nrf9160, flashed, they are working fine, now need to add to nrf Cloud and realized there are few ways to do that, all are not well described.

Is there any easy way to add device using web interface (with no digging into API part) ? When I just add device I get code 40411.

Will highly appreciate if there is step by step easy to follow short instruction how to set that up (including certificates to be added device side if needed)

The provisioning service (and the nRF Cloud Provisioning Sample) are not compatible with the nRF9160.
You will need to use either use JITP or Preconnect.

JITP may be sufficient for initial device testing, but is not recommended for production devices.

• To download credentials, click "Create JITP Certificates" on the https://nrfcloud.com/#/add-device/lte-device page.
• Input your device ID and create a PIN... click the download button.
• Use the Cellular Monitor application to load the downloaded JSON file and write the credentials to your device.
• Allow your device to connect to nRF Cloud... on the first connection, the device will be disconnected as JITP is performed.  Wait a few seconds...
• On the https://nrfcloud.com/#/add-device/lte-device page, enter your device ID and PIN, and click the add button.
• You should now see your device in the list https://nrfcloud.com/#/devices 
  • On the next connection attempt, your device should successfully connect and interact with nRF Cloud.

Preconnect is the recommended method. You can securely generate a private key on your device using an AT command and then create a device certificate. The steps are detailed here.  We have a python script that performs the required steps and outputs a CSV file to be uploaded to the website to onboard your devices.

• Clone the utils repo: https://github.com/nRFCloud/utils.git
• Navigate to utils/python/modem-firmware-1.3+ and install the required python packages: 
  • https://github.com/nRFCloud/utils/tree/master/python/modem-firmware-1.3%2B#prerequisites 
• Create a CA cert using create_ca_cert.py: https://github.com/nRFCloud/utils/tree/master/python/modem-firmware-1.3%2B#create-ca-cert
  • This only needs to be done once, you can use the created CA cert for all of your devices.
• Generate and install credentials on your device using device_credentials_installer.py: https://github.com/nRFCloud/utils/tree/master/python/modem-firmware-1.3%2B#device-credentials-installer
  • Use the files created by create_ca_cert.py for the script parameters --ca and --ca_key.
  • To see all the available option parameters, execute: python3 device_credentials_installer.py --help
• Upload the generated CSV file (default: onboard.csv) to the website: https://nrfcloud.com/#/add-device/bulk and click onboard.
  • You can check the status of the onboarding by navigating to https://nrfcloud.com/#/bulk-operation-history
• Successfully onboarded devices will now appear in https://nrfcloud.com/#/devices 
• Devices can now connect and interact with nRF Cloud

I followed steps in "Preconnect" option, generated all certificates, created CSV, but then I get these errors from device:

nrf_cloud_transport: MQTT input error: -128
 nrf_cloud_transport: Error disconnecting from cloud: -128

Which is not clear, as same code in another device (DK, so all certificates are there) works fine.

Please advice what I could be missing ?

after you uploaded your CSV file to nrf cloud does your device appear in your device list?

[FlashBack123]

Yes, it appeared after .csv upload. Though ID looks strange.

In project I have 

CONFIG_NRF_CLOUD_CLIENT_ID_SRC_IMEI=y

So I assume it had to look like nrf-IMEI

while in device console I see as 

50474335-3032-4ea2-8037-070a77228082

yes, you provisioned your device using the UUID, but your firmware is using the IMEI format.

you can either rebuild your firmware to use the UUID by setting the following configs:
CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y
CONFIG_MODEM_JWT=y

or re-provision your device, adding the following parameters to the device_credentials_installer.py command:
--id_imei --id_str nrf-

that will provision your device with the nrf-<IMEI> device ID format.
