nRFCloud, device self-assign to a group

Hi Vincent,

You can use any https client, including HTTPS Client (nordicsemi.com) to send REST API request.

Following is the REST API to change device tags. Remember to set CONFIG_HTTPS_HOSTNAME="api.nrfcloud.com" and replace nrf\samples\net\https_client\cert\DigiCertGlobalG2.pem with amazontrust.com/repository/AmazonRootCA1.pem since nRF Cloud is running on top of AWS.

#define HTTP_HEAD  \
	"PUT /v1/devices/50363953-3234-4ab4-8025-xxxxxxxxxxxxxx/tags HTTP/1.1\r\n"  \
    "Host: "CONFIG_HTTPS_HOSTNAME"\r\n"  \
	"Content-Type: application/json\r\n"  \
    "Authorization: Bearer a6a0d3f0fc4fd3b61ab47366772a7dxxxxxxxxxxxxx\r\n"  \
	"Content-Length: 17\r\n" \
	"Connection: close\r\n\r\n"\
	"[\"test3\",\"test4\"]"

Best regards,

Charlie

Hi Charlie,

My question concerns the device side.

Is it possible to implement this from the device side ? If so, how ?

For example, functions such as nrf_cloud_rest_shadow_device_status_update() will send some device's info to nRFCloud. However, I couldn't find any function that allows setting a group for the device.

Would nrf_cloud_rest_send_device_message() be the one to use

Thanks

Hi Vicent,

Yes, there is nRF Cloud API for Groups tag operations, you can even add several tags for the same device. See

Organizing devices with the nRF Cloud APIs (nordicsemi.com)

https://api.nrfcloud.com/v1/#tag/All-Devices/operation/UpdateDeviceTags

Best regards,
