## UCloud IOT SDK for rt-thread Package ## 1 介绍 UCloud IOT SDK for rt-thread Package 是基于[UCloud设备端C-SDK](https://github.com/ucloud/ucloud-iot-device-sdk-c)在RThread环境开发的软件包,用于连接uiot-core物联网平台 ### 1.1 SDK架构图 ![](https://uiot.cn-sh2.ufileos.com/sdk%E6%9E%B6%E6%9E%84%E5%9B%BE.png) ### 1.2 目录结构 | 名称 | 说明 | | ---- | ---- | | uiot | UCloud设备端C-SDK | | ports | 移植文件目录 | | samples | 示例目录 | | ├─mqtt | 静态注册收发消息示例 | | ├─dynamic_auth | 动态注册示例 | | ├─dev_model | 物模型示例 | | ├─ota | ota升级示例 | | ├─shadow | 设备影子示例 | | docs | 说明文档 | | LICENSE | 许可证文件 | | README.md | 软件包使用说明 | | SConscript | RT-Thread 默认的构建脚本 | ### 1.3 许可证 许可协议Apache 2.0。 ### 1.4 依赖 Tls功能需要mbedtls软件包 [ ] mbedtls: An portable and flexible SSL/TLS library ---- ## 2 如何打开软件包 menuconfig配置 - RT-Thread env开发工具中使用 `menuconfig` 软件包,配置产品及设备信息, 路径如下: ``` RT-Thread online packages ---> IoT - internet of things ---> IoT Cloud ---> [ ] ucloud-iot-sdk: ucloud iot sdk for uiot-core platform. ---> --- ucloud-iothub: ucloud iot sdk for uiot-core platform [ ] Enable Mqtt ucloud Device Config ---> Version (latest) ---> ``` ## 3 软件包的使用 根据产品需求选择合适的应用示例修改新增业务逻辑,也可新增例程编写新的业务逻辑。 ``` --- ucloud-iot-sdk: ucloud iot sdk for uiot-core platform. [*] Enable mqtt Auth Mode (Enable Static Register) ---> Ucloud Device Config ---> [ ] Enable Tls [ ] Enable Ucloud Mqtt Sample [ ] Enable Shadow [ ] Enable Ucloud Shadow Sample [ ] Enable Dev Model [ ] Enable Ucloud Dev Model Sample [ ] Enable Ota [ ] Enable Ucloud Ota Sample [ ] Enable Ucloud Debug Version (latest) ---> ``` - 选项说明 `Enable mqtt`:使能MQTT功能。 `Auth Mode (Enable static register)`:认证模式,分为静态认证和动态认证模式, (括号内为当前选择的模式)。 `Enable Static Register`:静态注册模式使用产品号,设备号,设备密钥认证 `Enable Dynamic Register`:动态注册模式使用产品号,设备号,产品密钥认证 `Ucloud Device Config `:根据认证模式填写当前设备认证要素,当认证模式为动态认证时,设备密钥可以不填写 `Enable TLS`: 是否使能TLS,若使能,则会关联选中mbedTLS软件包。 `Enable Ucloud Mqtt Sample`:使能mqtt收发消息的案例 `Enable Shadow`:使能设备影子功能 `Enable Ucloud Shadow Sample`:使能物模型的案例 `Enable Dev Model`:使能物模型功能 `Enable Ucloud Dev Model Sample`:使能物模型的案例 `Enable Ota`:使能远程升级版本的功能,若使能,则会关联选中ota_downloader软件包。 `Enable Ucloud Ota Sample`:使能远程升级版本的案例 `Enable Ucloud Debug`: 使能打印输出 `Version (latest) --->`: - 使用 `pkgs --update` 命令下载软件包 ### 2.2 编译及运行 1. 使用命令 scons --target=xxx 输出对应的工程,编译 2. 打开生成的工程,编译下载到设备中 ### 2.4 运行demo程序 系统启动后,在 MSH 中使用命令执行,以mqtt_sample为例: 启动案例:mqtt_test_example start 终止案例:mqtt_test_example stop 执行输出: msh />mqtt_test_example start establish tcp connection with server(host='mqtt-cn-sh2.iot.ucloud.cn', port=[1883]) msh />success to establish tcp, fd=4 Cloud Device Construct Successsubscribe success, packet-id=2 publish success, packet-id=3 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "0"} publish success, packet-id=4 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "1"} publish success, packet-id=5 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "2"} publish success, packet-id=6 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "3"} publish success, packet-id=7 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "4"} publish success, packet-id=8 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "5"} publish success, packet-id=9 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "6"} publish success, packet-id=10 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "7"} publish success, packet-id=11 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "8"} publish success, packet-id=12 Receive Message With topicName:/fahnimwwvph259ag/3um7h4fdiigf2yyh/upload/event, payload:{"test": "9"}
