Question

我需要使用SPP将KwikBlue-2 Module Development Kit连接到Nexus One上的Android BluetoothChat example。对于SPP设备，在将BluetoothChat example示例中的UUID更改为00001101-0000-1000-8000-00805F9B34FB之后，我能够使用tera术语连接和交换串行数据（一次）。然后我重新启动KwikBlue-2 Module Development Kit以验证连接是否可重复但是不断获得我尝试连接时java.io.IOException: Connection refused。有什么想法吗？

尝试取消配对/修复，然后它可能再次起作用。这似乎是Android上核心蓝牙支持的一个错误。

Android蓝牙java.io.IOException：连接被拒绝了？
