我想创建一个简单的程序，扫描蓝牙耳机(我正在测试一个PS3耳机)，然后连接到它。我正在使用bluetooth chat program example中的代码。但是我无法将它连接到任何东西。当它到达connect()时它给我一个I/O异常。连接/配对蓝牙耳机和Android
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
此线程在尝试与设备建立传出连接时运行。它贯穿始终;连接成功或失败。
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
public ConnectThread(BluetoothDevice device) {
mmDevice = device;
BluetoothSocket tmp = null;
// Get a BluetoothSocket for a connection with the given BluetoothDevice
try {
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
Log.e(TAG, "create() failed", e);
}
if (tmp == null){
Log.i(TAG, "tmp is NULL");
}
mmSocket = tmp;
}
public void run() {
Log.i(TAG, "BEGIN mConnectThread");
setName("ConnectThread");
// Always cancel discovery because it will slow down a connection
mAdapter.cancelDiscovery();
Log.i(TAG, "discovery is cancelled");
// Make a connection to the BluetoothSocket
try {
// This is a blocking call and will only return on a successful connection or an exception
mmSocket.connect(); //Doesn't like something here???
} catch (IOException e) {
Log.e(TAG, "IO error, ", e);
connectionFailed();
// Close the socket
try {
mmSocket.close();
} catch (IOException e2) {
Log.e(TAG, "unable to close() socket during connection failure", e2);
}
// Start the service over to restart listening mode
newTBluetoothService.this.start();
return;
}
// Reset the ConnectThread because we're done
synchronized (newBluetoothService.this) {
mConnectThread = null;
}
// Start the connected thread
connected(mmSocket, mmDevice);
}
public void cancel() {
try {
mmSocket.close();
} catch (IOException e) {
Log.e(TAG, "close() of connect socket failed", e);
}
}
}
这里是logcat的：

任何帮助深表感谢。

我正在使用2.2更新版和PS3蓝牙耳机在Droid X上进行测试。它正在配对，但不会连接。当我进入蓝牙设置时，我可以手动连接耳机。 –
