Platform topics

提示

Custom devices, DTUs, and communication modules usually use one subscribe topic and one publish topic.

• {productId}: platform product ID.
• {deviceNum}: device number, such as IMEI, MAC address, or a unique number generated by the platform.
• Topics marked as deprecated are no longer used after version 2.x.

1. Server-side topics

提示

• Platform command delivery topic: /{productId}/{deviceNum}/function/get.
• The server subscribes with wildcards so it can receive messages from all devices.
