Witajcie.

Mam mały problem z realizacją połączenia Bluetooth na Androidzie. Temat znajduje się trochę niżej, ale ten wątek będzie dotyczyć troszkę innej kwestii. Moja aktywność, w której chcę inicjować połączenie. Znajduje się w niej lista sparowanych i nowych urządzeń. Po kliknięciu chciałbym połączyć się z urządzeniem. Samo nawiązanie połączenia mam zrobione w onClickListenerze podłączonym do listy(działa, serwer wyświetla mi nazwę i adres podłączonego urządzenia) . Pozostaje kwestia jak automatycznie po nawiązaniu połączenia wysłać jakieś słowo na serwer. Kod Aktywności wygląda póki co tak (wersja robocza jeszcze, ale Androida uczę się od 2 tygodni, więc napisałem jak umiałem):

public class MainActivity extends Activity 
{
    private static final String TAG = "BTD";
    private static final boolean D = true;

    // Return Intent extra
    public static String EXTRA_DEVICE_ADDRESS = "device_address";

    // Member fields
    private BluetoothAdapter mBtAdapter;
    private BluetoothDevice mBtDevice;
    private ArrayAdapter<String> mPairedDevicesArrayAdapter;
    private ArrayAdapter<String> mNewDevicesArrayAdapter;
    private ListView pairedListView, newDevicesListView;
    private String address;
    public static final int MESSAGE_READ = 2;
    private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");
    private BluetoothSocket socket;
    private BluetoothDevice connect_device;

Jeśli zrobię tak jak powyżej i po prostu wywołam

mConnectedThread.write(bajty);

to nic nie przychodzi i dostaję informację a LogCat'ie mowiącą "Skipped 179 frames" itd. Podejrzewam, że chodzi tu o wątki, ale nie wiem jak się z tym uporać. Proszę o pomoc
