How to automatic pair to bluetooth device that is already paired

[kurar...@gmail.com]

The arduino with Bluetooth module is already paired in my Android phone. When I use the app that I made in AI2, I will always click the "select BT module" to choose and connect to the arduino. Can it have the function so that when the App in open it will automatically connect to the arduino? can it be done?
