Send signals from arduino to MIT app

Hey I have a project where I need to send signals from my arduino through HC-05 module to App. I would like to send a signal with a certain value every time I press one of my 4 buttons. I need my app to be able to read the signals from arduino.

Hope u guys can help :)

Smoke signals?

You can NOT send "signals" using bluetooth. You can ONLY send data.
