Hi Ranjith,

I think you should edit bsp.c file.

find this function and edit like this way. static void bsp_button_event_handler(uint8_t pin_no, uint8_t button_action)

case APP_BUTTON_PUSH: printf("BUTTON IS PRESSED\r\n");

            event = m_events_list[button].push_event;
            if (m_events_list[button].long_push_event != BSP_EVENT_NOTHING)
            {
                err_code = app_timer_start(m_button_timer_id,    BSP_MS_TO_TICK(BSP_LONG_PUSH_TIMEOUT_MS), (void*)&current_long_push_pin_no);
                if (err_code == NRF_SUCCESS)
                {
                    current_long_push_pin_no = pin_no;
                }
            }
            release_event_at_push[button] = m_events_list[button].release_event;
            break;
        case APP_BUTTON_RELEASE:
	printf("BUTTON IS RELEASE\r\n");

            (void)app_timer_stop(m_button_timer_id);
            if (release_event_at_push[button] == m_events_list[button].release_event)
            {
                event = m_events_list[button].release_event;
            }
            break;
        case BSP_BUTTON_ACTION_LONG_PUSH:
	printf("BUTTON IS PRESSED\r\n");

            event = m_events_list[button].long_push_event;
    }

before use printf to print on terminal you have to initialize uart. find Bellow attached jpg file and show output.
