So I think the easy way is to put a flag when you press one time to true, but before this put a if(flag) call your function.

If you want to have a time to press the second time, like only call your function if you press the same button 2 times within 5 seconds. After putting the flag to true you should start a timer with 5 seconds, and on the time handler when it finishes to put the flag = false. this way if you press within 5 seconds your function is called, if you press 2 times with 6 seconds apart then nothing happens.

by a flag I mean a variable that you state true when the case you want happens, and then on the main function you just scan for this flag and start the functions you want. But which of the two is your case?

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,
