ESP32C3基于Arduino框架下的 ESP32 RainMaker开发示例教程

ESP RainMaker

ESP RainMaker 是乐鑫推出的一个端到端平台。基于该平台，用户无需管理基础设施，可直接使用乐鑫的 ESP32-S2 SoC 快速实现物联网创意与想法。

乐鑫官方对ESP RainMaker介绍：https://www.espressif.com.cn/zh-hans/news/ESP-RainMaker

目前通过示例，将程序烧录到ESP32C3上，只实现了通过蓝牙连接到设备，在入网过程中，总是出错,代码上可能还需要完善才行。

esp-rainmaker-基于android版的APP应用下载地址

这个基于安卓的手机端APP，在各大APP应用市场可能没有上架找不到，通过官网提供的github找到了，基于苹果平台的APP,网上一搜就有了，应该上应用市场可以直接下载到，这里就不提供了。
Release v2.3.0
