Android 到蓝牙设备 (WT-11) 通信/连接

Question

因此，我们有一个 Android 应用程序，该应用程序应该与 Bluegiga WT-11 蓝牙模块配对，然后在服务器套接字上侦听来自设备的连接。我们使用 SPP 和 RFCOMM 与“众所周知的”UUID 00001101-0000-1000-8000-00805F9B34FB 进行通信。配对工作正常，但接受服务器套接字上的连接（使用 listenUsingRfcommWithServiceRecord() 创建，然后等待 accept()）无法可靠工作。它有时会起作用，但有时会完全停止工作，或者有时会间歇性地工作。

最令人困惑的是，手机似乎正在从设备获取连接，向 LogCat 吐出几行，然后完全忽略连接；设备认为连接失败，并且应用程序永远不会在 accept() 上获得任何连接。

这是当手机（Galaxy S II）获得连接但不执行任何操作时的 LogCat（我现在已经在几部手机上尝试过此操作，如果您需要其他手机的日志或成功的日志），请告诉我连接）：

@WBAN 你能帮忙解决这个问题吗？我发现你也做过类似的事情。

任何帮助将不胜感激！

谢谢！
