Android蓝牙通信编程

概述项目涉及蓝牙通信，所以就简单的学了学，下面是自己参考了一些资料后的总结，希望对大家有帮助。

项目涉及蓝牙通信，所以就简单的学了学，下面是自己参考了一些资料后的总结，希望对大家有帮助。
 以下是开发中的几个关键步骤：
1、首先开启蓝牙 
2、搜索可用设备 
3、创建蓝牙socket，获取输入输出流 
4、读取和写入数据
5、断开连接关闭蓝牙 @H_404_7@

下面是一个蓝牙聊天demo 
效果图： @H_404_7@

@H_404_7@@H_404_7@

在使用蓝牙是 BluetoothAdapter 对蓝牙开启，关闭，获取设备列表，发现设备，搜索等核心功能 @H_404_7@

下面对它进行封装：

在编程中遇到的问题:
 Exception:  Unable to start Service discovery
java.io.IOException: Unable to start Service discovery错误 
@H_404_7@

1、必须保证客户端，服务器端中的UUID统一,客户端格式为：UUID格式一般是"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
@H_404_7@

 例如：UUID.fromString("81403000-13df-b000-7cf4-350b4a2110ee");
 2、必须进行配对处理后方可能够连接 @H_404_7@

扩展：蓝牙后台配对实现（网上看到的整理如下）@H_404_7@

static public boolean createBond(Class btClass,BluetoothDevice btDevice) throws Exception { Method createBondMethod = btClass.getmethod("createBond"); Log.i("life","createBondMethod = " + createBondMethod.getname()); Boolean returnValue = (Boolean) createBondMethod.invoke(btDevice); return returnValue.booleanValue(); } static public boolean setPin(Class btClass,BluetoothDevice btDevice,String str) throws Exception { Boolean returnValue = null; try { Method removeBondMethod = btClass.getDeclaredMethod("setPin",new Class[] { byte[].class }); returnValue = (Boolean) removeBondMethod.invoke(btDevice,new Object[] { str.getBytes() }); Log.i("life","returnValue = " + returnValue); } catch (SecurityException e) { // throw new RuntimeException(e.getMessage()); e.printstacktrace(); } catch (IllegalArgumentException e) { // throw new RuntimeException(e.getMessage()); e.printstacktrace(); } catch (Exception e) { // Todo auto-generated catch block e.printstacktrace(); } return returnValue; } // 取消用户输入 static public boolean cancelPairingUserinput(Class btClass,BluetoothDevice device) throws Exception { Method createBondMethod = btClass.getmethod("cancelPairingUserinput"); // cancelBondProcess() Boolean returnValue = (Boolean) createBondMethod.invoke(device); Log.i("life","cancelPairingUserinputreturnValue = " + returnValue); return returnValue.booleanValue(); }

 

然后监听蓝牙配对的广播  匹配“androID.bluetooth.device.action.PAIRING_REQUEST”这个action
 然后调用上面的setPin(mDevice.getClass(),mDevice,"1234"); // 手机和蓝牙采集器配对
 createBond(mDevice.getClass(),mDevice);
 cancelPairingUserinput(mDevice.getClass(),mDevice);
 mDevice是你要去连接的那个蓝牙的对象，1234为配对的pin码
