Problems connecting with bluetooth Android

I'm trying to open a socket bluetooth between a milestone and a pc but the device can not connect. I hope I am sending the code help.

public class Bluetooth_V2 extends Activity {
 public TextView tela;
 public ListView telaDevice;
 public BluetoothAdapter bluetooth;
 public String endBluetooth;
 public String endDevice;
 public String nomeDevice;
 public ArrayAdapter<String> nomeBluetooth;
 private static final String info = "DEBUG";
 private static final int DISCOVERABLE_REQUEST = 0;
 private static final int DISCOVERY_REQUEST = 0;
 public BroadcastReceiver mReceiver = null;
 public ArrayList<String> deviceDescoberto;
 public BluetoothDevice deviceRemoto;
 public BluetoothServerSocket btserver;
 public BluetoothSocket serverSocket;
 public UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
 public OutputStream outStream;
 public InputStream instream;
 public BluetoothSocket socket;

public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  tela = (TextView) findViewById(R.id.telaMsg);
  telaDevice = (ListView) findViewById(R.id.telaDevice);

  bluetooth = BluetoothAdapter.getDefaultAdapter();

  nomeBluetooth = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1); 
  telaDevice.setAdapter(nomeBluetooth);

  Log.d(info, "Recebeu adaptador");

  if(bluetooth==null)
  {
   Log.d(info,"Bluetooth nao suportado");
   tela.append("Bluetooth nao suportado");
  }

  if(!bluetooth.isEnabled())
  {
   Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
   startActivityForResult(enableBtIntent,RESULT_OK);
  }

  tela.append("\nNome:"+bluetooth.getName());
  tela.append("\nEndereço:"+bluetooth.getAddress());

  bluetooth.startDiscovery();
  Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
  startActivity(discoverableIntent);
  //discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCO
