what you mean by double push? do you mean push two buttons, or push the button two times in a row?

If it's the first case, you can put a flag on your button press handler and do what you want if both flags are on.

For the second case you can put a flag on your button handler and start a timer, then on the timer handler another flag signaling the end of the time for the double push, and if you press the button inside the time you configured on the timer (so, without setting the flag of the timer) you go to the function you want to execute.

You also should say which softevice and SDK you are using;)

Hope this helps,
