Android的蓝牙java.io.IOException异常：连接被拒绝？ [英] Android Bluetooth java.io.IOException: Connection refused?

问题描述

我需要连接一个 KwikBlue-2模块开发套件到Android BluetoothChat例如的使用SPP一个的Nexus One。 我可以用万亿长期变化的UUID中的 BluetoothChat例如的例子来00001101-0000-1000-8000-00805F9B34FB的SPP设备。 然后我重新加电的 KwikBlue-2模块开发套件以验证连接是重复的，但不断得到 java.io.IOException异常：连接被拒绝当我尝试连接。 任何想法？

解决方案

尝试取消配对/修复，然后会再次合作。这似乎是与核心蓝牙支持Android上的错误。

I need to connect a KwikBlue-2 Module Development Kit to the Android BluetoothChat example on a Nexus One using SPP. I was able to connect and exchange serial data (once) using tera term after changing the UUID in the BluetoothChat example example to 00001101-0000-1000-8000-00805F9B34FB for SPP devices. Then I power cycled the KwikBlue-2 Module Development Kit to verify that the connection was repeatable but continually get java.io.IOException: Connection refused when I try to connect. Any ideas?

解决方案

Try unpair/repair and then it may work once again. This seems to be a bug with the core Bluetooth support on Android.
