我正在尝试连接到运行2.0.1固件的Moto Droid的Zeemote（http://zeemote.com/）游戏控制器。下面的测试应用程序确实连接到设备（LED闪烁），但之后立即断开连接。
我正在粘贴下面的两个测试应用程序：一个实际上尝试从输入流中读取，另一个只是坐在那里，等待设备在5秒后断开连接。是的，我确实有第三个版本:)首先等待ACL_CONNECTED，然后打开套接字，但它的行为没有什么新东西。
一些背景信息： 我可以使用bluez工具（也附带日志）从我的笔记本电脑连接到Zeemote。我确信Droid 能够与Zeemote交谈，因为来自Market的'Game Pro'可以正常使用它（但它是一个驱动程序/服务，所以它可能使用较低级别的API？ ）。
我注意到'adb bugreport'既没有报告Zeuote的UUID也没有RFCOMM频道，而是针对所有其他设备（包括Moto HS815耳机，其中'sdp浏览'没有报告任何内容的另一个哑设备）。此外，当设备启动时，Zeemote的优先级为0（其他优先级为100 +）。
我在这里很茫然，我在这方面工作了很长时间以至于我的想法用完了所以任何帮助都会非常感激（即使你不知道 的答案:)）
谢谢， 最大
此应用尝试从设备中实际读取。

尝试更改用于创建RfcommSocket的代码：
sock = zee.createRfcommSocketToServiceRecord(
UUID.fromString("8e1f0cf7-508f-4875-b62c-fbb67fd34812"));
代码：
Method m = zee.getClass().getMethod("createRfcommSocket", new Class[] { int.class });
sock = (BluetoothSocket) m.invoke(device, 1);
还尝试在此m.invoke（device，1）中更改范围1-3中的参数值; 当连接将被连接，但在您尝试阅读时中止，请再次调用方法test（）。 很简单：
for(int i=0;i<3;i++){ if(!testDone) test(); }

如果我理解正确，您的应用无法从设备中看到任何数据？
一件小事：尝试没有hipns的UUID。在我的RFCOMM应用程序中，我实际上将UUID定义为长整型常量。
此外，你的test（）方法的编写方式让我相信test（）正在建立连接，定义一个线程，告诉它启动并立即返回。换句话说，你的线程引用了一个来自线程外部的变量，这是test（）方法的一部分，但是当test（）死掉时，它的变量也是如此。
简而言之，在线程之外尝试测试并首先在那里工作。一种简单的方法是使用Thread.run（）而不是thread.start（）。 .run（）在前台运行它（因此阻塞test（），因此在线程完成之前它不会返回）。
对于较长期的解决方案，您可能希望将蓝牙变量定义为gloibal / member变量，这样它们就不会超出范围，并且始终可供您的线程使用。
