# 应用命令

## 网络配置

配置完成后需要重启开发板

* 设置wifi ssid和密码

  ```
  kv set wifi_ssid <SSID>
  kv set wifi_psk <PWD>
  ```

* 设置mac地址

  ```
  iwpriv wifi_debug set_mac <MAC_ADDR>
  ```
## 低功耗设置

* 低功耗使能配置

  ```
  kv setint lpm_en <en>
  ```

* VAD使能配置

  ```
  kv setint vad_en <en>
  ```

* VAD阈值配置

  ```
  kv setint vad_th <num>
  ```

  \<num>：取值0~31，数值越大阈值越高

## ai测试命令

* 播放音乐命令：

  ```
  ai music <url>
  ```
* 播放tts文本

  ```
  ai tts <text>
  ```
* 播放系统通知音

  ```
  ai notify <num>
  ```
* 调节系统音量

  ```
  ai vol <+/-/num>
  ```

## 切换云资源

* 切换云命令（需重启生效）

  ```
  kv setint mitasr <num>
  ```

	\<num>：

	* 0：默认配置，语音云A（包括少量歌曲用于演示）
	* 1：IoT云
	* 2：语音云B（不含歌曲资源）

## websocket录制麦克风数据

* 步骤如下：
  * 将PC设备和开发板连接在同一个局域网网段；

  * PC端启动websocket服务：

    ```
    cd solutions_cb5631/smart_speaker_cb5631/tools/record_server
    mkdir download
    python server.py <IP>:<Port> ./download/
    ```

    \<IP>是PC的本机IP地址，\<Port>是端口号，例如：192.168.50.1:8090

  * 开始录制麦克风数据

    ```
    yv micrec start ws://<IP>:<Port> micdata.pcm
    ```

    \<IP>和\<Port>与上一步保持一致

  * 停止录制麦克风数据

    ```
    yv micrec stop
    ```

录制完成后，在`download`目录下会生成xxxx_mic_micdata.pcm文件；包含5路数据：mic1/mic2/ref/空/aec

* 播放并检查PCM文件方法：

  1. 下载Audacity开源软件：[下载地址](https://www.audacityteam.org/)
  2. 选择“文件” -> “导入” -> “原始数据”， 导入格式如下：
		* 编码：Signed 16-bit PCM
		* 字节序：小尾端（little-endian）
		* 声道：5声道
		* 采样率：16000Hz
