title: How to Auto-Connect to Arduino with Android App?
body: <p>I am currently working on an android application that blocks texting while driving. It connects through Bluetooth to an Arduino Bluno that is connected to a car via the OBD-II port and scans for data received from a car (either 0 for a non-drive state or 1 if the car is going above 0 mph i.e. driving) and blocks texting if the car is in a drive state. </p>
  
  <p>What I would like to do is have the app/phone automatically connect to the Arduino once I enter the car with the phone and start driving. I am not familiar with how to do so, if I need to use the native Android Bluetooth connection data to scan for the hardware or if there is some other approach. Can I get some guidance as to how I can auto-connect? </p>
