Android蓝牙java.io.IOException:连接被拒绝了？

Question

我需要使用SPP 将KwikBlue-2模块开发套件连接到Nexus One上的Android BluetoothChat示例.在将BluetoothChat示例示例中的UUID更改为SPP设备的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).然后我循环使用KwikBlue-2模块开发套件来验证连接是否可重复,但java.io.IOException: Connection refused在我尝试连接时不断获得 .有任何想法吗？

尝试取消配对/修复,然后它可以再次工作.这似乎是Android上核心蓝牙支持的一个错误.
