title: Bluetooth connection throwing error
body: <p>I have written a normal code to connect to a standard bluetooth device ( a wocket). What I am doing is connecting to the wocket (which is just a piece of bluetooth chip), as a client. I am using a random UUID to connect to the wocket. But the connect method is throwing a IO Exception telling me that it is not able to connect to the Bluetooth device. The code that I am using is from Android Developers forum here :
  <a href="http://developer.android.com/guide/topics/connectivity/bluetooth.html" rel="nofollow">http://developer.android.com/guide/topics/connectivity/bluetooth.html</a></p>
  
  <p>private class ConnectThread extends Thread {
      private final BluetoothSocket mmSocket;
      private final BluetoothDevice mmDevice;</p>
  
  <pre><code>public ConnectThread(BluetoothDevice device) {
      // Use a temporary object that is later assigned to mmSocket,
      // because mmSocket is final
      BluetoothSocket tmp = null;
      mmDevice = device;
  
      // Get a BluetoothSocket to connect with the given BluetoothDevice
      try {
          // MY_UUID is the app's UUID string, also used by the server code
          tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
      } catch (IOException e) { }
      mmSocket = tmp;
  }
  
  public void run() {
      // Cancel discovery because it will slow down the connection
      mBluetoothAdapter.cancelDiscovery();
  
      try {
          // Connect the device through the socket. This will block
          // until it succeeds or throws an exception
          mmSocket.connect();
          **This call is throwing and IOException saying:
          java.io.IOException Discovery Failed.
  </code></pre>
  
  <p>** </p>
  
  <pre><code>    } catch (IOException connectException) {
          // Unable to connect; close the socket and get out
          try {
              mmSocket.close();
          } catch (IOException closeException) { }
          return;
      }
  
      // Do work to manage the connection (in a separate thread)
      manageConnectedSocket(mmSocket);
  }
  
  /** Will cancel an in-progress connection, and close the socket */
  public void cancel() {
      try {
          mmSocket.close();
      } catch (IOException e) { }
  }
  </code></pre>

  <p>What could be the reason the wocket is throwing an IOException. I don't think it makes any sense to connect to it being a server as for a server you establish a UUID and then you expect the client to have the same UUID, which is not possible in my case because I cannot program the wocket.</p>
  
  <p>I am using an HTC one x with Android 4.0 as the testing device.</p>
  
  <p>Thank you in advance.</p>
