Hi!

Define your button in this method:

static void buttons_init(void) {
    // Note: Array must be static because a pointer to it will be saved in the Button handler
    //       module.

    static app_button_cfg_t buttons[] =
    {
        {BUTTON_2, false, BUTTON_PULL, button_event_handler}
    };

    app_button_init(buttons, 1, BUTTON_DETECTION_DELAY); }

And define your event handler that you refer to in that method as well:

static void button_event_handler(uint8_t pin_no,uint8_t button_action)
{
   // Stop or start execution
}

And then just call buttons_init() in your main.

This is how I do it when using S130 on nRF51822 but I guess this kind of stuff is the same on your setup.

Kind regards
