简介
手机端发送文字，开发板发出对应语音信息。
- 本案例需要使用到阿里云平台连接网络。通过阿里IOT studio应用开发移动应用，手机端发送文字信息，文字信息通过阿里云下发给开发板，开发板播放对应文字语音。
准备
本案例需要的硬件

| 4G天线 | 1 |
硬件接口
代码流程
1、连接阿里云平台。
2、接收云平台下发物模型信息。
3、根据物模型信息播放语音
功能实现
1、物联网平台开发
第一次使用物联网平台的读者，需要开通实例后使用物联网平台功能。也可以使用免费的公共实例进行开发，在阿里云物联网平台中，左上角选择‘华东2-上海’，点击‘公共实例’，即可开通。
1、平台产品创建可参考haas506 2.0开发教程-aliyunIoT
2、创建产品属性（添加物模型）
-
选择产品功能定义–编辑草稿
-
添加自定义功能
-
设置标识符、数据类型、读写类型参数，标识符（light）要与代码保持一致。点击确定。
-
发布上线，点击确定。
2、设备端开发
- 第一次使用开发板的读者可以按照haas5062.0开发教程-导学篇搭建开发环境。
- 搭建完后复制以下代码到Visual Studio Code，复制产品证书到代码相应位置。
代码
复制代码到VS code
