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。

谢谢 克里斯

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。 –
