Configure the firmware

To configure the firmware, complete the following mandatory steps:

1. Run the following command to print the Azure IoT DPS ID scope, which your devices use during device provisioning:

node cli info -o iotHubDpsIdScope

1. Use this ID scope as the value for the CONFIG_AZURE_IOT_HUB_DPS_ID_SCOPE configuration variable.

2. Use 11 as the value for CONFIG_AZURE_IOT_HUB_SEC_TAG.

3. Use 11 as the value for CONFIG_AZURE_FOTA_SEC_TAG.

4. Comment in the remaining Azure settings in the prj.conf file:

   CONFIG_AZURE_IOT_HUB=y
   CONFIG_AZURE_IOT_HUB_DPS=y
   CONFIG_AZURE_IOT_HUB_AUTO_DEVICE_TWIN_REQUEST=y
   CONFIG_AZURE_IOT_HUB_DEVICE_ID_APP=y
   CONFIG_AZURE_IOT_HUB_MQTT_PAYLOAD_BUFFER_LEN=2048
   CONFIG_AZURE_IOT_HUB_MQTT_RX_TX_BUFFER_LEN=2048
   CONFIG_AZURE_IOT_HUB_TOPIC_PROPERTY_BAG_PREFIX=n
   CONFIG_AZURE_IOT_HUB_STACK_SIZE=4096
   CONFIG_AZURE_FOTA=y
   CONFIG_AZURE_FOTA_TLS=y
   

5. Comment in the Azure logging settings in the overlay-debug.conf file:

   CONFIG_AZURE_FOTA_LOG_LEVEL_DBG=y
   CONFIG_AZURE_IOT_LOG_LEVEL_DBG=y
   CONFIG_AZURE_JOBS_LOG_LEVEL_DBG=y
   

6. Comment out the nRF Connect for Cloud settings in the prj.conf file:

   # CONFIG_AGPS=y
   # CONFIG_AGPS_SRC_NRF_CLOUD=y
   # CONFIG_NRF_CLOUD=y
   # CONFIG_NRF_CLOUD_AGPS=y
   # CONFIG_NRF_CLOUD_CONNECTION_POLL_THREAD=y
   # CONFIG_NRF_CLOUD_PGPS=n
   # CONFIG_NRF_CLOUD_SEND_TIMEOUT=y
   # CONFIG_GPS_MODULE_NMEA=y
   

7. Comment out the nRF Connect for Cloud logging settings in the overlay-debug.conf file:

   # CONFIG_NRF_CLOUD_FOTA_LOG_LEVEL_DBG=y
   # CONFIG_NRF_CLOUD_GPS_LOG_LEVEL_DBG=y
   # CONFIG_NRF_CLOUD_LOG_LEVEL_DBG=y
   

After completing the configuration, compile the firmware either using your own development environment or using Docker and then create the device credentials.

Note

See the documentation on nRF9160: Asset Tracker v2 application (1.6.0) for all available configuration options.
