USO

Adicione ao seu projeto:

	allprojects {
		repositories {
			...
			maven { url "https://jitpack.io" }
		}
	}

	dependencies {
	        compile 'com.github.tiagohm:BlueDroid:VERSION'
	}

Adicione as permissões:

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Declare BlueDroid:

BlueDroid bt = new BlueDroid(Context, ConnectionDevice, ConnectionSecure);

ConnectionDevice.ANDROID

ConnectionDevice.OTHER

Verificar se Bluetooth está disponível:

if(!bt.isAvailable()) {
  finish();
  ...
}

Verificar se está ativado e ativá-lo se necessário:

@Override
public void onStart() {
    super.onStart();
    if(!bt.isEnabled()) {
      Intent i = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
      startActivityForResult(i, REQUEST_ENABLE_BT);
    } else {
      ...
    }
}

Encerrá-lo ao fechar o aplicativo:

@Override
  protected void onDestroy() {
    super.onDestroy();
    bt.stop();
  }

Procurar por dispositivos:

bt.doDiscovery(Activity);

Adicionar o tratamento da requisão da permissão:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
{
   bt.checkDiscoveryPermissionRequest(requestCode, permissions, grantResults);
}

Exibir os dispositivos encontrados numa lista e conectar ao clicar em um item:

new BlueDiscoveryDialog(Context, bt).show();

Para desconectar:

bt.disconnect();

Para enviar:

String texto = "123456";
bt.send(texto.getBytes(Charset.forName("US-ASCII")), LineBreakType.UNIX);

Receber dados:

bt.addDataReceivedListener(new BlueDroid.DataReceivedListener() {
  @Override
  public void onDataReceived(byte data) {
    ...
  }
} );

Outros eventos:

bt.addDiscoveryListener(new BlueDroid.DiscoveryListener()
{
    @Override
    public void onDiscoveryStarted()
    {
    }

    @Override
    public void onDiscoveryFinished()
    {
    }

    @Override
    public void onNoDevicesFound()
    {
    }

    @Override
    public void onDeviceFound(Device device)
    {
    }

    @Override
    public void onDiscoveryFailed()
    {
    }
});

bt.addConnectionListener(new BlueDroid.ConnectionListener()
{
    @Override
    public void onDeviceConnecting()
    {
    }

    @Override
    public void onDeviceConnected()
    {
    }

    @Override
    public void onDeviceDisconnected()
    {
    }

    @Override
    public void onDeviceConnectionFailed()
    {
    }
