You need call "app_button_enable();" function

You are not using scheduler in your program so change this:

APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, true);

to this:

APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, false);

Try to test if button callback ever called with led turn on inside button_event_handler().

In the main:

nrf_gpio_cfg_output(LED_1);

And in button callback:

static void button_event_handler(uint8_t pin_no, uint8_t button_action)
{
    nrf_gpio_pin_set(LED_1);
    if (button_action == APP_BUTTON_PUSH)
    {
...

Show me your main loop. Or better just copy all the main function and post it on pastebin. If you init scheduler then you could just left APP_BUTTON_INIT unchanged.

I changed to APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, false); and also included the init scheduler. But the result is same. thanks in advance, rahul

I don't see you init scheduler. If you don't use scheduler in your program then change this:

APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, true);

to this

APP_BUTTON_INIT(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY, false);

These are the functions

static void timers_init(void) { uint32_t err_code;

// Initialize timer module
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, false);

// Create timers
err_code = app_timer_create(&m_timeout_timer_id,
		APP_TIMER_MODE_SINGLE_SHOT,
		tag_timeout_handler);
APP_ERROR_CHECK(err_code);

leds_init();
timers_init(); gpiote_init(); buttons_init(); ble_stack_init(); gap_params_init(); services_init();
advertising_init();
conn_params_init();
sec_params_init();

//start advertising to connect to a ble device
advertising_start();

Show your initialization code in main function before main loop.
