蓝牙规范相关文档 Core Specification 5.2 核心规格 5.2，该规范定义了创建可互操作的Bluetooth 设备所需的技术。
《Core_v5.2.pdf》
Mesh Model(v1.1) 本Bluetooth 规范定义了模型（以及它们所需的状态和消息），这些模型用于在mesh 网络中的节点上执行基本功能，超出了Bluetooth Mesh 配置文件 规范中定义的基础模型。
本规范包括定义跨设备类型标准功能的通用模型，以及支持关键mesh 场景的模型，如照明控制、传感器、时间和场景。
《MshMDL_v1.1.pdf》
Mesh Profile(v1.0.1) 该Bluetooth 规范定义了基本要求，以实现可互操作的mesh 网络解决方案，用于Bluetooth 低能量无线技术。
《MshPRFv1.0.1.pdf》
Mesh Device Properties 本规范包含Bluetooth Mesh 配置文件 和Bluetooth Mesh 模型规范所要求的设备属性的定义。
但是跟之前的有些区别，我主要看的之前的版本：《MMeshDeviceProperties_v1.2.pdf》
GATT Specification Supplement GATT Specification Supplement | Bluetooth® Technology Website。
好像可以在线看：《GATT Specification Supplement》

一、GPIO

需要知道的是，这个蓝牙开发板里面其实使用的也是AliOSThings的内核，所以对于GPIO的一些接口函数什么的，跟前面学习AliOSThings的时候是一样的。

1. 官方文档

我们可以看一下官方文档：GPIO · 开发指南 (alicdn.com)，这里有对GPIO接口函数的详细说明：

2. 使用实例

2.1 led.c

3. 编译工程

aos make bluetooth.led@tc825x

4. 烧录程序

5. 实验现象

串口会有以下打印信息：

image-20231224194329068

然后我们会看到三个灯同时间隔1秒闪烁。

二、PWM

1. 官方文档
