生活物联网平台 SDK 是阿里云 IoT 针对生活物联网平台所提供的设备端 SDK。SDK 基于 C 语言开发，代码开源，提供了 API 供您调用，用于实现与阿里云 IoT 平台通信以及其它的辅助功能（例如 WiFi 配网、本地控制等）。当前 ali-smartliving-device-sdk-c 是基于 SDK 仓库, 分支 rel_1.6.0 进行开发。
本文基于 linux 环境，介绍 ESP 设备对接阿里云生活物联网平台 & 天猫精灵 IoT 开放平台的具体流程，供读者参考。
- linux 环境
用来编译 & 烧写 & 运行等操作的必须环境。
windows 用户可安装虚拟机，在虚拟机中安装 linux。
根据生活物联网平台官方文档，在生活物联网平台创建产品，创建设备，同时自动产生 product key, product secert, device name, device secret。
product key, product secert, device name, device secret 将在 6.2.3 节用到。
如果您熟悉 ESP 开发环境，可以很顺利理解下面步骤; 如果您不熟悉某个部分，比如编译，烧录，需要您结合官方的相关文档来理解。如您需阅读 ESP-IDF 编程指南文档等。
toolchain 设置参考 ESP-IDF 编程指南。
- ESP8266 平台：烧录工具位于 ESP8266_RTOS_SDK 下
./components/esptool_py/esptool/esptool.py - ESP32 & ESP32S2 平台：烧录工具位于 esp-idf 下
./components/esptool_py/esptool/esptool.py
esptool 功能参考:
$ ./components/esptool_py/esptool/esptool.py --help
- esp-ali-smartliving SDK, 通过该 SDK 可实现使用 MQTT 协议，连接 ESP 设备到阿里生活物联网平台。
- Espressif SDK
- ESP32 & ESP32S2 平台: ESP-IDF
- ESP8266 平台: ESP8266_RTOS_SDK
Espressif SDK 下载好后：
ESP-IDF: 请切换到 release v3.3.2 tag 版本：git checkout v3.3.2如果需要使用 ESP32S2 模组，请切换到 release/v4.2 版本：git checkout release/v4.2
ESP8266_RTOS_SDK: 请切换到 release/v3.3 版本：git checkout release/v3.3
参考 工具链的设置
在 esp-ali-smartliving 目录下执行：
cd ali-smartliving-device-sdk-c
make reconfig (选择SDK平台)
make menuconfig (选择相关功能配置,默认不需要修改,该步骤可以省略)
make (生成相关头文件和库文件)
在 esp-ali-smartliving 目录下执行：
cd examples/solutions/smart_light
make defconfig
make menuconfig
如果需要编译esp32s2版本, 请按照如下步骤修改编译:
修改 ESP-IDF SDK，按照 链接 进行修改。
执行如下命令，以 solo 示例为例，目前只支持 solo 和 smart_light 示例。
cd examples/solo/example_solo
idf.py set-target esp32s2
idf.py menuconfig
如果使用 cmake 编译 esp32，不需要 set-target。
- 配置烧写串口
2.生成最终 bin
make -j8
使用 esp32s2 生成 bin
idf.py build
-
按照第 4 节搭建好编译环境，配置好 SDK 路径。
-
运行工程目录下 build.sh 文件，根据提示进行编译，当前该工具只支持 example_solo 和 smart_light 两个示例。
脚本可以支持包括：芯片 SDK 的选择，ali-smartliving-sdk-c 的编译配置，示例的编译。
按照提示执行，直至出现 Now build all bin successfully!!! 表示编译成功，可以按照提示进行烧录运行。
将 USB 线连接好 ESP 设备和 PC，确保烧写端口正确。
make erase_flash
使用 esp32s2 擦除 flash
idf.py -p (PORT) erase_flash
注：无需每次擦除，擦除后需要重做 6.2.3。
make flash
使用 esp32s2 烧录程序
idf.py -p (PORT) flash
参考 量产说明 文档烧录三元组 NVS 分区。
make monitor
使用 esp32s2 运行
idf.py -p (PORT) monitor
如将 ESP32 拨至运行状态，即可看到如下 log： log 显示了 ESP32 基于 TLS 建立了与阿里生活物联网平台的安全连接通路，接着通过 MQTT 协议订阅和发布消息，同时在生活物联网平台控制台上，也能看到 ESP32 推送的 MQTT 消息。
