android ble 蓝牙4.0开发日志（一）

 

此次android开发针对三星gs3开发，特以此文给正在开发ble4.0的童鞋们一点启示。

我们要开发基于android ble4.0的app，那么我们首先需要一个开发包，也就是一个android.jar或者是ble.jar，这其中包含了我们进行ble开发的一些类，下面我贴上这些类，我贴上一些类的代码，给大家参考下，不再是某些人的类介绍而已。

由于这些类都是通过反编译的，可能有错，这些类是不需要加入到源码中的，大家可以进群（群号见最后）下载ble_sunsang.jar,注意这里肯定有童鞋说我加入了，eclipse给我编死了，这是因为你把这个jar放到了工程里了，这里要以外部包的方式引入喔，切记。

开始介绍相关类：BluetoothLEClientChar.java

此类是用于接收发送数据的 封装类，也就是说蓝牙通过uuid发送和接收都是通过此类来完成。

BluetoothLEClientProfile类用来管理和LE设备的连接 也就是断开，连接，掉线，refresh 等… 我们要和le来连接我们必须重新写一个子类然后 继承于BluetoothLEClientProfile。

BluetoothLEClientService.java 顾名思义 此是le设备通信服务类，这个类主要用于监听UUID，UUID你可以理解为是一个特殊的端口，特殊的通信道路，只有LE设备和手机两侧 UUID一致然后才能进行通信，这个服务就是用来管理通信的。  也需要自己重新写子类然后继承于BluetoothLEService.java
