使用 C Link SDK 接入_云市场(Marketplace)-阿里云帮助中心

目标

设备能通过 linksdk 及少量的修改就可以快速接入 Tuya 物联网平台阿里云版，使设备具有连云的能力。

前置条件

已准备好环境说明
已获取C Link SDK
已获取设备认证信息

步骤

使用 IDE 打开下载好的工程文件

工程目录结构大致如下图所示(本文档仅旨在演示如何使用 LinkSDK 接入，因此未选其他附件能力)

本文档后续均使用demos>mqtt_basic_demo.c演示 LinkSDK 接入 hedv。该 demo 只提供最基础的 MQTT 连接功能，其他 pub / sub 的能力需要基于此 demo 开发或是选取其他 demo。

替换证书

在 IDE 中打开下载好的工程，找到external > ali_ca_cert.c 文件（该文件中提供了 CA 和自签两类证书供开发者选择），如下图所示：

复制下文代码，粘贴替换（下列文件中也同时提供了 CA 和自签两类证书，开发者可以自行选择）：
