我正在尝试将我的 HTC myTouch 3G 与蓝牙设备配对，该设备将通过 SPP 将数据流式传输到手机。我查看了聊天示例，发现它们缺少我需要的东西，因为我需要高数据速率，并且聊天示例确实阻塞了 UI 线程。但这就是说我的主要问题是当我尝试连接当前未配对的设备时，蓝牙 API 表示如果设备需要配对代码，它将自动弹出一个对话框。这永远不会发生。我如何确保它确实如此？这是我的代码...

BluetoothSocket btSocket;
String macAddress = data.getStringExtra("mac");
Log.d(TAG, "Found Device " + macAddress);

// Get the Bluetooth adapter on the device
BluetoothAdapter bta = ((MyApplication)this.getApplication()).getBtState();
BluetoothDevice btDevice = bta.getRemoteDevice(macAddress);
BluetoothSocket tmp = null;
try {
    tmp = btDevice.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));
} catch (IOException e) {
    e.printStackTrace();
}
if (tmp != null) {
    btSocket = tmp;
    bta.cancelDiscovery();

    try {
        btSocket.connect();
    } catch (IOException e) {
        try {
            Log.e(TAG, "------------- Close IOException");
            btSocket.close();
        } catch (IOException e2) {
            Log.e(TAG, "unable to close() socket during connection failure", e2);
        }
    }
}

这是我也得到的错误：

关于这个似乎是一个错误的一个奇怪的事情是，如果我运行此代码并且它失败了，那么我关闭蓝牙并将其重新打开，设备显示为在堆栈中配对。据我了解，myTouch 上的蓝牙芯片是 2.1，而我们尝试连接的芯片是 1.2

I'm currently having some troubles with Bluetooth (using SPP) on some phones. One thing you could try, is to use reflection when creating the socket.

I've used a Nexus S while developing my Bluetooth service (I'm actually using the listenUsingRfcommWithServiceRecord-method) it works fine on that phone. Also works fine on SonyEricsson Xperia ARC and SonyEricsson X10 Mini Pro. It didn't work on HTC Wildfire (2.2.1), HTC Legend (2.2) nor on Samsung Galaxy S (2.2.1).

I should also mention that the device I'm receiving data from uses Bluetooth 1.2 too, like yours, so that should not be a problem.

When I tried using reflection I suddenly succeeded on the Wildfire, unfortunately still no progress on Legend nor on the Galaxy S. This is where I'm stuck. Many forums claim some manufacturers have a proprietary Bluetooth stack, so I guess this is what's causing these problems. Anyway, good luck! 

UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");

Method m = mAdapter.getClass().getMethod("createRfcommSocketToServiceRecord", new Class[] { UUID.class });
tmpSocket = (BluetoothServerSocket) m.invoke(mAdapter, new Object[] { MY_UUID });

再次，这似乎是该手机的蓝牙中的一个错误，其他具有相同 BT 芯片和版本的手机没有这个问题
