Make Bluetooth connection alive for multiple activity

In my application i want to send value from multiple activity to connected Thread,i don't know to solve this problem please help me
Example:
I want to send String string ="#FFFFFF000*";from First-activity to service class,
String string= "#000000000*" ;from Second- activity to service class

public class BluetoothDataService1 extends Service {
final int handlerState = 0;

public void handleMessage(android.os.Message msg)

if (msg.what == handlerState)
String readMessage = (String) msg.obj;
recDataString.append(readMessage);

This is my Activity

public class SendActivity extends Activity implements View.OnClickListener {
Button on;
BluetoothDataService1 bluetoothDataService1;
public boolean isBound = false;
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_send);
on= (Button) findViewById(R.id.btnon);
on.setOnClickListener(this);


@Override
public void onStart()
super.onStart();
Intent intent = new Intent(this, BluetoothDataService1.class);
bindService(intent, connection, Context.BIND_AUTO_CREATE);


@Override
public void onClick(View v)
if (isBound)

// Intent intent=new Intent (SendActivity.this,BluetoothDataService1.class);
// intent.putExtra("ON","#ffffff00" );
// startService(intent);


private ServiceConnection connection = new ServiceConnection()
@Override
public void onServiceConnected(ComponentName className, IBinder service)
BluetoothDataService1.LocalBinder binder = (BluetoothDataService1.LocalBinder) service;
bluetoothDataService1 = binder.getService();
isBound = true;


@Override
public void onServiceDisconnected(ComponentName arg0)
isBound = false;

;
@Override
public void onStop()
super.onStop();
if (isBound)
unbindService(connection);
isBound = false;

String string="#FFFFFF000"

like `public static void send()
static veriableName="FFFFFF000"
// sending code here whatever
