android示例蓝牙聊天到串行蓝牙适配器（rs232）通信

我正在尝试与android示例蓝牙聊天应用程序中的串行蓝牙适配器**r进行通信。。 我已将UUID更改为：“00001101-0000-1000-8000-00805F9B34FB”
但即便如此，它还是说“无法连接” 我正在使用2.3.3 android设备和L*M048蓝牙串行适配器**

代码与gooogle提供的blutooth聊天示例相同 想知道必须对该代码进行哪些更改，才能使用超级终端上的COM1端口与LM048蓝牙串行适配器通信

你能发布一些代码，以及你收到的错误的堆栈跟踪信息吗？它与更改UUID一起工作。。。我已经设置了设备设置wrong@chalukya3545--您现在正在使用的UUID。因为我现在面临着同样的问题..这个“00001101-0000-1000-8000-00805F9B34FB”
