# AT device #
|
||||
|
||||
## 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:ESP32、ESP8266、M26等,其中 ESP8266 和 M26 设备完成对 `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 AT 用户手册](https://git.rt-thread.com/packages/rt_at/blob/master/README.md)。
|
||||
|
||||
### 1.1. 文件结构 ###
|
||||
|
||||
| 名称 | 说明 |
|
||||
| ---- | ---- |
|
||||
| at_socket_esp8266.c | ESP8266 模块针对 AT 组件的移植文件,实现 AT socket |
|
||||
| at_socket_m26.c | M26 模块针对 AT 组件的移植文件,实现 AT socket |
|
||||
| at_client_sample.c | ESP8266 模块 AT Client 功能示例文件 |
|
||||
|
||||
### 1.2 许可证 ###
|
||||
|
||||
|
||||
### 1.3 依赖 ###
|
||||
|
||||
- RT_Thread 3.0+
|
||||
- RT_Thread AT 组件
|
||||
- RT_Thread SAL 组件
|
||||
|
||||
## 2. 获取方式 ##
|
||||
|
||||
AT device 软件包是对 AT 组件库和 AT socket 功能的移植,需开启 AT 组件库和 AT socket 功能来获取 AT device 软件包。
|
||||
|
||||
先要开启 AT 组件库和 AT socket 功能, 具体路径如下所示:
|
||||
|
||||
RT-Thread Components --->
|
||||
Network stack --->
|
||||
Socket abstraction layer --->
|
||||
protocol family type --->
|
||||
[ ] Support lwIP stack
|
||||
[*] Support AT Commands stack
|
||||
|
||||
开启 AT socket 功能之后,默认开启 AT device 软件包, 具体路径如下所示:
|
||||
|
||||
Privated Packages of RealThread --->
|
||||
-*- AT DEVICE: RT-Thread AT component porting or samples for different device
|
||||
AT socket device modules (Not selected, please select) --->
|
||||
Version (latest) --->
|
||||
|
||||
- `AT socket device modules`: AT 设备选择,目前支持 ESP8266、M26 等设备;
|
||||
- `Version`: 下载软件包版本;
|
||||
|
||||
## 3. 注意事项 ##
|
||||
|
||||
- AT device 软件包默认设备类型为未选择,使用时需要指定使用设备型号;
|
||||
- AT device 软件包目前处于 `beta` 测试阶段, 推荐在 menuconfig 选项中选择 `latest` 版本;
