Pushing Firmware Upgrade Status Change Notifications

Typical Scenario

After an NA subscribes to firmware upgrade status change notifications (the notification type is fwUpgradeStateChangeNotify) on the IoT platform, the IoT platform sends a notification message to the NA when the firmware upgrade status changes.

API Function

This API is used by the IoT platform to push notification messages to an NA that has subscribed to firmware upgrade status change notifications.

Note

When Subscribing to Management Data of the IoT Platform, 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.
An NA receives the content of a push message by inheriting the PushMessageReceiver class and rewriting the callback API.
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.
