- I have written an interrupt program to blink an led at port P1.01 by pressing the button 1.So i added the code in ble_app_blinky example so i can blink the led from the board and use the mobile app to connect to the board and blink the led. But once i add the interrupt program code in the main program the board stops advertising.any help.Both the codes are working individually.here is the code
