调试软件
软件名称：nRF Connect 安卓版本 或者使用LightBlue
软件使用
链接蓝牙设备
打开软件后搜索需要链接的蓝牙设备，点击connect链接设备
上图显示的为广播到的设备信息，点击RAW可以查看具体的数据。
广播数据的格式为
Length：AD Type：AD Data
长度：广播类型：广播数据
type（0xFF）为厂家自定义数据，上图为阿里蓝牙的数据
查看设备信息
其中有几个比较重要的概念Profiles, Services，Characteristics，UUID。
- Profiles表示一种规范，一个标准的通信协议，它存在于从机中。蓝牙组织规定了一些标准的Profiles，例如 HID OVER GATT ，防丢器 ，心率计等。每个profile中会包含多个 Services，每个 Services代表从机的一种能力。
- Services表示服务，在ble从机中一般有多个服务，例如电量信息服务、系统信息服务等，每个service中又包含多个characteristic特征值。每个具体的characteristic特征值才是ble通信的主题。比如当前的电量是80%，所以会通过电量的characteristic特征值存在从机的profile里，这样主机就可以通过这个characteristic来读取80%这个数据。
- Characteristics表示特征值，ble主从机的通信均是通过characteristic来实现，可以理解为一个标签，通过这个标签可以获取或者写入想要的内容。
- UUID表示统一识别码，Services和Characteristics都需要一个唯一的uuid来标识
一句话来说，Profiles是相当与一个设备的模板，每个Profiles中会包含多个 Services，每个service中又包含多个Characteristics。
下面一下实际的蓝牙设备：
其中“Generic Access”服务、“Generic Attribute”服务都属于标准的服务，Unknown Service是一些自定的服务。

收发数据
每个特征边上有个箭头，表示数据的读写。
点击向下读取数据，点击向上发送数据。发送数据可以选择数据类型，填写发送的数据，高级选项可以选择发送的数据是“Request（请求）”和“Command（命令）”类型。如果需要多条发送可以点击ADD VALUE
开启监听接收
点击图标开始接收监听模式，监听该Characteristic的NOTIFY
数据。右滑界面，可以看到接收到的每条数据。
应用开发
所谓开发蓝牙应用程序，其实就是开发service和characteristic。通过API，添加自己需要的characteristic和service，你自己的蓝牙设备就诞生了。只要characteristic和service是符合GATT规范的，你可以随意添加任何characteristic和service，并将他们组合成一个专门的蓝牙设备。

附录
Bluetooth Base UUID
UUID是一个128位的值。为了减轻存储和传输128位UUID值的负担，已预先分配了一系列UUID值，以分配给经常使用的已注册目的。 该预分配范围中的第一个UUID被称为Bluetooth Base UUID，其值从蓝牙分配的数字文档中为00000000-0000-1000-8000-00805F9B34FB。 预分配范围内的UUID值的别名表示为16位或32位值。 这些别名通常称为16位和32位UUID，但是要注意，每个别名实际上代表一个128位UUID值。16位UUID对应的完整UUID为0x0000[16位UUID]-0000-1000-8000-00805F9B34FB
