XR829芯片适配
1. 修改设备树
查看原理图：
原设备树中，WL_REG_ON与原理图的不匹配，修改为PB12。
蓝牙的设备树节点无需修改：
与原理图引脚符合：
2. 添加内核模块
进入SDK根目录，执行：
make menuconfig
取消勾选xr829-40M，选上xr829。
3. 添加xr829固件
Firmware负责实现Wi-Fi和蓝牙的连接管理、数据传输、安全加密以及其他底层操作。
把xr829 with 40M sdd取消勾选。
4. 启动odhcp6c服务
odhcp6c的核心作用在于简化并自动化IPv6网络环境下的地址配置过程，确保设备能够顺利接入并通信。
5. wifi测试
SDK根目录下，执行编译make，打包pack。
烧录到开发板上。

6. 蓝牙测试
6.1 蓝牙通话HFP
蓝牙HFP（Hands-Free Profile）是一种蓝牙配置文件，它允许用户通过蓝牙设备进行免提通话。HFP的实现通常建立在RFCOMM协议之上，并定义了音频网关（AG）和免提设备（HF）之间的通信方式，使用AT指令进行控制和状态信息的交换。
在开发板中，执行bt_test -i，打开蓝牙电源、D1-H开发板和控制器XR829的数据传输通道HCI进入交互模式：

6.2 蓝牙音频A2DP
蓝牙音频A2DP（Advanced Audio Distribution Profile）区别于HFP的另一种蓝牙配置文件，主要用于音乐播放和其他音频流应用，它提供了一种从音频源设备（如智能手机、平板电脑或笔记本电脑）到音频接收设备（如蓝牙耳机、扬声器或车载音频系统）的音频传输机制。
A2DP定义了两种主要角色：Source（源）和Sink（接收器）。
6.2.1 Source
Source设备是数字音频流的发起者，它负责将音频数据编码并通过蓝牙发送给一个或多个Sink设备。
开发板中，执行bt_test -i -p a2dp-source，打开Source模式并进入交互模式：

Sink设备接收来自Source的音频数据，对其进行解码，并播放音频。Sink设备还可以实现远程控制功能，允许用户控制播放、音量等。
开发板中，执行bt_test -p a2dp-sink，打开Sink模式：

打开手机连接上蓝牙，播放音乐，找个耳机插上D1H开发板耳机孔，即可听到音乐。
如果想要使用扬声器的接口来播放音乐，需要做以下设置：
在SDK根目录下执行make menuconfig，选上：
在package/libs/tinyalsa/，执行mm -B：
ubuntu@ubuntu1804:~/tina-d1-h/package/libs/tinyalsa$ mm -B
ubuntu@ubuntu1804:~/tina-d1-h/package/libs/tinyalsa$ cd /home/ubuntu/tina-d1-h/out/d1-h-nezha/compile_dir/target/tinyalsa-1.1.1/ipkg-install/usr/bin/
ubuntu@ubuntu1804:~/tina-d1-h/out/d1-h-nezha/compile_dir/target/tinyalsa-1.1.1/ipkg-install/usr/bin$ ls
tinycap tinymix tinypcminfo tinyplay
ubuntu@ubuntu1804:~/tina-d1-h/out/d1-h-nezha/compile_dir/target/tinyalsa-1.1.1/ipkg-install/usr/bin$ adb push ./* /usr/bin
在开发板中，可以执行以下：
#转换为喇叭播放：
tinymix set "LINEOUTL Output Select" 1
tinymix set "LINEOUTR Output Select" 1
#设置音量：
tinymix set "LINEOUT volume" 15
tinymix set "LINEOUT Switch" 1
即可通过扬声器接口从喇叭上播放音乐。
