【问题描述】：
我需要使用 SPP 将 KwikBlue-2 Module Development Kit 连接到 Nexus One 上的 Android BluetoothChat example。
在将 BluetoothChat example 示例中的 UUID 更改为 SPP 设备的 00001101-0000-1000-8000-00805F9B34FB 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不断得到
java.io.IOException: Connection refused 当我尝试连接时。
有什么想法吗？

【问题讨论】：
-
在黑暗中拍摄 - 您是否检查过重启后套件和 Nexus One 是否仍然配对？
-
是的。仍然配对，只是未连接。
