Android蓝牙IOException:连接被拒绝

注：也张贴在

我正在尝试连接到蓝牙RFCOMM设备。我使用sl4a并从Python脚本进行连接。我有两台android设备运行相同的android版本2.3.4

在一个设备上（Galaxy S2，非常接近股票内核，根），脚本运行良好，并连接到RFCOMM设备。在另一台设备上，一款异国情调的Winmate E430T（我怀疑是体积相当小的专门耐用Android手机），我得到了一个

java.io.IOException:连接被拒绝

我试着运行示例代码

bluetooth\u chat.py

，但没有成功，该代码是用于Android到Android连接的。我收到了相同的错误消息，这表明问题不在我的代码中，而更多的是Winmate手机的状态（是否有根目录、已安装的软件、配置）

有人见过类似的东西吗？我看到了关于联保部队维修的帖子，我试了两次，但都没用。在安装了Python和所有模块之后，我还尝试重新启动Winmate

守则：

编辑2012年9月13日09:55：我从市场上试用了

蓝牙聊天应用程序（BILL RAY），它允许我的两部手机聊天，我可以从任何一方连接：这个问题至少可以用Java解决。但是
bluetooth\u chat.py
示例仍然不起作用

编辑10:45：我在比恩希尔试过，但仍然在SL4A中，有同样的问题，在我的S2上工作，在我的Winmate上失败：

代码：

logcat与此类似：

我们有一个为ARM编译的PyBluez副本，在这里可能有用

它不是纯Python，但安装起来很简单；您只需将egg文件的副本下载到droid，打开Python4Android应用程序，点击导入模块并选择egg文件

我以前用过这种东西，没有问题

有故障的WinMate是否可能运行Android ICS？我想是4.0.x。@Cyrill Holweck有更新吗？
