## 1. 简介 ##
AT device 软件包是由 RT-Thread AT 组件针对不同 AT 设备的移植文件和示例代码组成，目前支持的 AT 设备有：ESP8266、ESP32、M26、MC20、RW007、MW31、SIM800C、W60X 、SIM76XX、A9/A9G、BC26 、AIR720、ME3616系列设备等，目前上述设备都完成对 `AT socket` 功能的移植，及设备通过 AT 命令实现标准 socket 编程接口，完成 socket 通讯的功能，具体功能介绍可参考 [《RT-Thread 编程指南》](https://www.rt-thread.org/document/site/programming-manual/at/at/)AT 命令章节 。
