Querying Device Activation Status

Typical Scenario

After an NA registers a device on the IoT platform, the activation status of the device is false before the device connects to the IoT platform for the first time. When the device connects to the IoT platform for the first time, the activation status of the device is true regardless of whether the device is online, offline, or abnormal. The NA can call this API to query the activation status of the device to check whether the device has connected to the IoT platform.

API Function

This API is used by an NA to query the activation status of a device on the IoT platform to determine whether the device has connected to the IoT platform.
