Real Time-Thread（以下简称 RT-Thread）是一个嵌入式实时多线程操作系统，C SDK 支持以 软件包 的形式应用到 RT-Thread 操作系统，本文向您介绍如何使用 RT-Thread 快速接入腾讯云物联网开发平台。
操作步骤
RT-Thread 接入腾讯云物联网开发平台可以分为以下4个步骤。
步骤一：开发环境安装
步骤二：软件包下载
1. 执行
scons --menuconfig 命令打开配置面板。
勾选 【RT-Thread online packages】>【IoT - internet of things】>【IoT Cloud】>【tencent-iot-sdk】。[ ] OneNET: China Mobile OneNet cloud SDK for RT-Thread ----[ ] GAgent: GAgent of Gizwits in RT-Thread ----[ ] Ali-iotkit: Aliyun cloud sdk 'iotkit-embedded' for RT-Thread ----[ ] Azure IoT SDK: Microsoft azure cloud SDK for RT-Thread ----[*] Tencent-IoT: Tencent Cloud IoT Explorer Platform SDK for RT-Thread --->[ ] jiot-c-sdk: JIGUANG IoT Cloud Client SDK for RT_Thread ----[ ] ucloud_iot_sdk: Ucloud iot sdk for uiot-core platform. ----[ ] Joylink Cloud SDK for IoT platform ----
2. 执行
pkgs --update 命令更新软件包，腾讯云物联网 C SDK 将被下载到 packages 目录。步骤三：编译与运行
1. 执行
scons --menuconfig 命令打开配置面板，对 C SDK 进行配置。选择路径：
RT-Thread online packages => IoT - internet of things => IoT Cloud => tencent-iot-sdk 。--- Tencent-IoT: Tencent Cloud IoT Explorer Platform SDK for RT-Thread(0WUKPUCOTC) Config Product Id(dev001) Config Device Name(N6B8M91PB4YDTRCpqvOp4w==) Config Device Secret[ ] Enable dynamic register[ ] Enable err log upload[ ] Enable multi thread function[*] Enable TLS/DTLSSelect Product Type (Data template protocol) --->[*] Enable Event[*] Enable Action[*] Enable Smart_light Sample[*] Enable OTAConfig OTA download by https or http (Download by http) --->[ ] Enable GateWayVersion (latest) --->
参数说明：
Config Product Id：配置产品 ID，平台创建生成。
Config Device Name：配置设备名，平台创建生成。
Config Device Secret：配置设备密钥，平台创建生成。考虑到嵌入式设备大多没有文件系统，暂时没有支持证书设备配置。
Enable dynamic register： 是否使能动态注册功能及示例，若使能，需配置动态注册的产品密钥。
Enable err log upload： 是否使能错误日志上传云端。
Enable TLS/DTLS： 是否使能 TLS，若使能，则会关联选中 mbedTLS 软件包。
Select Product Type：产品类型为自定义或者数据模板协议产品。
Enable event：选用数据模板的前提下，是否使能事件功能。
Enable Action：选用数据模板的前提下，是否使能行为功能。
Enable Smart_light Sample：是否使能智能灯场景示例。
Enable OTA：是否使能 OTA 示例。若使能 OTA 可进一步选择下载使用 HTTPS 或者 HTTP。
Enable GateWay：是否使能网关示例。
Version：软件包版本选择，v3.1.2及其以后的版本只支持物联网开发平台，若需使用物联网通信平台，请选择 v3.0.2 及其之前的版本。
2. 编译并运行示例程序。
本文以数据模板智能灯 + TLS 为例进行介绍，展示设备和物联网开发平台基于 数据模板协议 的通信示例使能 TLS。物联网开发平台下发控制灯为红色的命令，设备端收取消息，打印颜色，并上报对应消息。
