For this to work, you need to define Button_detection_delay right?

Can I know the function which you have written for defininng this detection of delay☺

The button handler should have APP_IRQ_PRIORITY_HIGH priority by default. This is set in the app_gpiote_init function. app_button uses app_gpiote library.

This link could also help with understanding the debouncing functionality further.

It looks like you use pullup for your button, which means it is not floating, so that is not the reason for your problem.

If it still does not work, you could try the example on this thread, to see if it works better.

If you are using softdevice and a lot of other interrupts, a possible explanation is that the button signal is toggled to fast and an interrupt is missed, see this thread.
