Android藍牙java.io.IOException：連接被拒絕？

Question

我需要在Nexus One上使用SPP將KwikBlue-2 Module Development Kit連接到Android BluetoothChat example。 對於SPP設備，將BluetoothChat example示例中的UUID更改爲00001101-0000-1000-8000-00805F9B34FB後，我能夠使用tera term連接和交換串行數據（一次）。 然後我重新上電KwikBlue-2 Module Development Kit以確認連接是可重複的，但在嘗試連接時不斷獲得 java.io.IOException: Connection refused。 任何想法？

Answer 1

嘗試取消配對/修復，然後會再次工作。這似乎是Android上核心藍牙支持的一個缺陷。
