安卓蓝牙串口例子修改

BluetoothChatService.java
的第49行         
    private static final UUID MY_UUID = UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66");                        
中的字符串不同，于是把他替换成蓝牙串口服务 (SPP) 的 UUID                        
    private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
保存后运行程序到手机上，把电脑上的蓝牙打开，打开电脑上的串口助手，波特率随便设置就可以了

不支持中文是因为Android上的字符是UTF-8 的，而你传送的是GB2312编码的。所以会出现乱码。
这个是我认为的，可能不对。
我是这样做的，发送的时候要这样转一下：


send = message.getBytes("GBK");


接收后也要转一下：
readMessage = new String(readBuf, 0, msg.arg1,"GBK");
