    description: "the parameters for chip-tool(matter command-line tool) to send"
    properties:
      valueType: "StringArray"
      readWrite: "RW"

  • 定义一个命令行工具设备，提供StringArray类型的参数cmdParams，能将接收到的字符串数组转化为chip-tool命令行参数，然后执行，最后将返回执行结果。

• 定义一个Matter灯泡类型设备，提供qrcode_payload解析、设备匹配入网及退网、设备开关控制，设备状态读取等命令功能。

• 每一个命令均支持读写操作，通过读操作可以获取上一次写操作的返回结果。

通过os/exec执行chiptool，根据不同功能输入相应参数，并解析返回结果。
