   在研究了网上的android蓝牙串口代码后发现其代码大部分内容与android系统自带的 示例程序 BluetoothChat 相似。于是我直接把示例程序导入eclipse项目中编译并行在手机上，尝试直接用此软件连接到电脑的蓝牙串口，但是始终不成功。我开始分析代码，发现有区别的地方是 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
