如何解决如何将蓝牙连接从活动传递到新活动？请帮助我

这是我的主要活动`

我想将蓝牙连接传递给另一个新的意图“modosactivity”

public class Home extends AppCompatActivity implements View.OnClickListener{
    String address = null;
    private ProgressDialog progress;
    BluetoothAdapter myBluetooth = null;
    BluetoothSocket btSocket = null;
    private boolean isBtConnected = false;

    static final UUID myUUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

    private CardView alarme,definicoes,sobre,bluetooth,modos;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate (savedInstanceState);
        setContentView (R.layout.activity_home);

        Intent newint = getIntent();

        address = newint.getStringExtra (MainActivity.EXTRA_ADDRESS);

        alarme = (CardView) findViewById(R.id.alarme_card);
        definicoes = (CardView) findViewById(R.id.definicoes_card);
        modos = (CardView) findViewById(R.id.modos_card);
        bluetooth = (CardView) findViewById(R.id.bluetooth_card);
        sobre = (CardView) findViewById(R.id.sobre_card);

        new ConnectBT().execute(); //chama a class de ConnectBT para se conectar

        //adicionar Click listener para novo layout
        modos.setonClickListener(this);
        definicoes.setonClickListener(this);
        alarme.setonClickListener(this);
        bluetooth.setonClickListener(this);
        sobre.setonClickListener(this);

    }

    //transições onclick
    @Override
    public void onClick(View v){
        Intent i;

        switch (v.getId ()) {
            case R.id.modos_card:
                i = new Intent (this,ModosActivity.class);
                ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeCustomAnimation(getApplicationContext(),R.anim.fade_in,R.anim.mover_direita);
                ActivityCompat.startActivity(Home.this,i,activityOptionsCompat.toBundle());
                ///startActivity (i);
                break;
            case R.id.alarme_card:
                i = new Intent (this,AlarmeActivity.class);
                startActivity (i);
                break;
            case R.id.bluetooth_card:
                i = new Intent (this,BluetoothActivity.class);
                startActivity (i);
                break;
            case R.id.sobre_card:
                i = new Intent (this,SobreActivity.class);
                startActivity (i);
                break;
            case R.id.definicoes_card:
                i = new Intent (this,DefinicoesActivity.class);
                startActivity (i);
                break;
            default:
                break;

        }

    }

    //method que é o que faz aparecer aquelas notificações de ex: erro
    private void msg(String s)
    {
        Toast.makeText (getApplicationContext (),s,Toast.LENGTH_LONG).show ();
    }

    private class ConnectBT extends AsyncTask<Void,Void,Void>  // UI thread
    {
        private boolean ConnectSuccess = true; //if it's here,it's almost connected

        @Override
        protected void onPreExecute()
        {
            progress = ProgressDialog.show(Home.this,"Conectando...","Aguarde um pouco!");  //Irá ser mosTrado uma caixa de texto enquanto o dispositivo se conecta ao HC-06
        }

        @Override
        protected Void doInBackground(Void... devices) //while the progress dialog is shown,the connection is done in background
        {
            try
            {
                if (btSocket == null || !isBtConnected)
                {
                    myBluetooth = BluetoothAdapter.getDefaultAdapter();//vai buscar o dispositivo bluetooth
                    BluetoothDevice dispositivo = myBluetooth.getRemoteDevice(address);//conecta  o dispositivo bluetooth e verifiva se está disponivel
                    btSocket = dispositivo.createInsecureRfcommSocketToServiceRecord(myUUID);//cria uma conexão RFCOMM (SPP)
                    BluetoothAdapter.getDefaultAdapter().canceldiscovery();
                    btSocket.connect();//começa a conexão
                }
            }
            catch (IOException e)
            {
                ConnectSuccess = false;
            }
            return null;
        }


        @Override
        protected void onPostExecute(Void result)
        {
            super.onPostExecute(result);

            if (!ConnectSuccess)
            {
                msg("Não foi possível se ligar ao dispositivo.Tente Novamente!");
                finish();
            }
            else
            {
                msg("Conectado.");
                isBtConnected = true;
            }
            progress.dismiss();
        }
    }
}

我已经有一个活动，可以通过蓝牙连接到我的 MainActivity。 但是现在我想要一个新活动，这样我就可以将数据发送到蓝牙，但我无法做到这一点。 有谁知道如何将蓝牙连接转移到新活动？
