Hello Maximilian

Thank you for your answer. I managed to send the appName to the device shadow, using what you suggested.

Hi!

After digging a little bit through the code, I found the part where this string is set: in `modem_info_params.c:49`, this is set to `PROJECT_NAME`. In our samples, we add `zephyr_compile_definitions(PROJECT_NAME=${PROJECT_NAME})` to CMakeLists.txt to define `PROJECT_NAME`.

Since this is handled by the Modem Info library, make sure the corresponding KConfig is enabled: `CONFIG_MODEM_INFO_ADD_DEVICE=y`.

Hello,

Sorry for the delay.

I will check internally what is the proper way to update the shadow and get back to you.

Those two links may be also of some help:

Best regards,

Hello

Using nrf_cloud_coap_shadow_get() it only returns the "control" and "config" fields within the reported field of the shadow register.

The appName field is included in the "device" field of the shadow.

Moreover, the "device" field does not updated from my application code.
I have enabled configs such as the following to update the "device" field of the shadow with the relevant information.

CONFIG_NRF_CLOUD_SEND_DEVICE_STATUS_CONN_INF=y      # Include connection information with device status
CONFIG_NRF_CLOUD_SEND_DEVICE_STATUS_NETWORK=y       # Include network status information with device status
CONFIG_NRF_CLOUD_SEND_DEVICE_STATUS_SIM=y           # Include SIM card information with device status
CONFIG_NRF_CLOUD_SEND_SERVICE_INFO_FOTA=y           # Add supported FOTA types to the "serviceInfo" section
CONFIG_MODEM_INFO=y
CONFIG_MODEM_INFO_ADD_NETWORK=y
CONFIG_MODEM_INFO_ADD_DEVICE=y
CONFIG_MODEM_INFO_ADD_DATE_TIME=y
CONFIG_MODEM_INFO_ADD_SIM=y
CONFIG_MODEM_INFO_ADD_SIM_ICCID=y
CONFIG_MODEM_INFO_ADD_SIM_IMSI=y

Should the nrf_cloud_coap_shadow_get() return the "device" field as well?
In this case how can I update the "device" field?

Thank you

Have you tried getting the shadow first with nrf_cloud_coap_shadow_get()and then editing the resulting JSON and then modifying it and sending it back with nrf_cloud_coap_shadow_state_update()?

Best regards,

Michal

Hello

Yes, but I was not able to figure this out.

Hello,

Have you looked into the shadow-related functions in our API documentation?
