Hi,
Your android code not working even not sending messages or receiving.
What I did here???
I upload your arduino code in my arduino nano board. Then develop arduino app for simply connect and send message using your code. But no luck.
How I know???
I try S2 terminal App It's working. Your arduino code well responding with S2 terminal.
Problem:
Device is connecting well with arduino but not sending & Receiving msg even not throwing any exception.
Here is my activity...

    public class MainActivity extends Activity {
BluetoothArduino mBlue ;
 @Override 
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mBlue = BluetoothArduino.getInstance(this,"Arduino");
    mBlue.Connect();
    Toast.makeText(this,mBlue.getLastMessage(),Toast.LENGTH_SHORT).show();
     Button b=(Button)findViewById(R.id.buttonOn);
     Button c=(Button)findViewById(R.id.buttonSearch);
     b.setOnClickListener(new OnClickListener(){

             @Override
             public void onClick(View p1)
             {

                 mBlue.SendMessage("Hi from Android!");
             }


     });
     c.setOnClickListener(new OnClickListener(){

             @Override
             public void onClick(View p1)
             {
                 Toast.makeText(getApplicationContext(),mBlue.getLastMessage(),Toast.LENGTH_SHORT).show();

             }


         });
 }



}

It will be a good addition to implement serialEvent function of the SoftwareSerial class to use the advantage of separating the serial events from the loop function.

I can't find BC417 Module for sale on Amazon. Can you direct me to a place I can buy it. I would like to contribute to your repo.

hi i tried your library, but i get this error when i call Connect() method

[#]Error while conecting: Attempt to invoke virtual method 'android.bluetooth.BluetoothSocket android.bluetooth.BluetoothDevice.createRfcommSocketToServiceRecord(java.util.UUID)' on a null object reference

Function "run", beginning at line 111 in BluetoothArduino.java program file, has never been called during the execution. Due to which no message received or delivered in the app.
