android自带的示例程序 BluetoothChat 变蓝牙串口助手

bbs_sn=5289768&bbs_page_no=1&search_mode=4&search_text=duxingkei&bbs_id=9999，突然想到通过我的安卓手机蓝牙串口配合蓝牙串口模块可以实现许多有意思的应用：手机蓝牙遥控汽车 手机蓝牙转红外遥控器甚至遥控家电。

   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
