Android : Android device.connect() returns Host is down

I have a bluetooth device on a list view, it´s a sensor bug BR-BUTTON-S3A. I´m trying to connect to the device (the server), so when I push a button on this remote device I can receive the sign on my app runnig on Android. Here is my code:

//getting the remote device and calling connect metod
public void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        BluetoothDevice device =(BluetoothDevice)l.getItemAtPosition(position);
        ConnectThread ct = new ConnectThread(device);  
        ct.run();
    }

//connecting to remote device on a new thread
    public class ConnectThread extends Thread {
        private BluetoothSocket mmSocket;
        private final BluetoothDevice mmDevice;

        public ConnectThread(BluetoothDevice device) {
            BluetoothSocket tmp = null;
            mmDevice = device;
            ParcelUuid[] uuids  = device.getUuids();
            try {
                tmp = device.createRfcommSocketToServiceRecord(uuids[0].getUuid());
            } catch (IOException e) {
                e.printStackTrace();
            }
            mmSocket = tmp;
        }

        public void run() {
            mBluetoothAdapter.cancelDiscovery();
            try {
                Method m = mmDevice.getClass().getMethod("createRfcommSocket", new Class[] { int.class });
                mmSocket = (BluetoothSocket) m.invoke(mmDevice, 1);
                mmSocket.connect();
            } catch (IOException connectException) {
                try {
                    connectException.printStackTrace();
                    mmSocket.close();
                } catch (IOException closeException) { }
                return;
            } catch (NoSuchMethodException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
            InputStream tmpIn = null;
            OutputStream tmpOut = null;
            try {
                tmpIn = mmSocket.getInputStream();
                tmpOut = mmSocket.getOutputStream();
                Toast.makeText(getBaseContext(), "InputStream" + tmpIn.toString(), Toast.LENGTH_SHORT).show();
                Toast.makeText(getBaseContext(), "OutputStream" + tmpOut.toString(), Toast.LENGTH_SHORT).show();
            } catch (IOException e) {
                Toast.makeText(getBaseContext(), "No se obtuvieron los datos del dispositivo bluetooth", Toast.LENGTH_SHORT).show();
            }

        }

        /** Will cancel an in-progress connection, and close the socket */
        public void cancel() {
            try {
                mmSocket.close();
            } catch (IOException e) { }
        }
    }

The problem is when I do mmSocket.connect(), then I get the error "Host is down" with no printable stack trace. I tried to get devices bonded before stablish rf connection but I didn´t work either.

Apreciate any help Thanks!
