static void advertising_init(void)
{
    uint32_t               err_code;
    ble_advertising_init_t init;

    memset(&init, 0, sizeof(init));

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = false;
    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

    init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;

    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

Here is my advertising_init function.

void Button_Handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action){   
      ready_to_flash_led = true ;
      SET_LED(LED_1, ON);
}

while(1){
      
    if(ready_to_flash_led == true ){
           
          write_flash_led(0x30);
          ready_to_flash_led = false;       
    }        
}

Here is my button handler. When i press button LED goes on, but in main while loop on if sentence doesnt trigger writing to flash function. If i run code in beacon mode or advertising in idle mode it goes into while loop.

What, exactly, do you mean by that.

It doesn't seem to make much sense - pretty much all of the SDK examples enter their main while loop while they are advertising!
