Pushing Device Service Information Change Notifications

Updated on 2022-02-24 GMT+08:00

Typical Scenario

After an NA subscribes to device service information change notifications (the notification type is serviceInfoChanged) on the IoT platform, the IoT platform sends a notification message to the NA when the IoT platform delivers a command to the device to modify the device service information.

API Function

This API is used by the IoT platform to push notification messages to an NA that has subscribed to device service information change notifications.

Note

  1. When subscribing to platform service data, an NA must subscribe to the specified callback address in the API description. The server and port in the callback address are the public IP address and specified port of the NA.
  2. An NA receives the content of a push message by inheriting the PushMessageReceiver class and rewriting the callback API.
  3. If the callback address is not the address of the NA, the NA must implement the original callback API. For details on the API content, see Message Push in the Huawei IoT Platform Northbound API Reference.
