IoT Platform provides the device tagging feature. You can manage devices by customizing tags. This article describes how to configure Link SDK for C to update or delete tags.

Prerequisites

Background information

  • For more information about the Alink data format of device tags, see Device tags.
  • For more information about how to add device tags in the IoT Platform console, see Add device tags.
  • For more information about how to manage device tags by using IoT Platform API operations, see the following articles:

Process

The application program calls the API operations of Link SDK for C to connect with IoT Platform over MQTT and send a request to submit or delete device tags. Each device tag is in the key:value format.

The following figure shows the process. In this example, the ./demos/devinfo_posix_demo.c application program is used.
