Cannot include delay.h in pin_change int example?

Question

I am trying to control an led by using the interupt function? and keep the led on for 2 seconds but i cannot include delay funtion.

I

In the code you have posted above you have commented out the call to nrf_drv_gpiote_init(). GPIOTE will not work without this function, and you will never enter the event handler to toggle the GPIO. Have you tried debugging to check for error codes?
