GPIO interrupt after wake up

Hello

My custom board has only 1 button and I'm trying to detect 3 button clicks. The first click is waking up the device and the other 2 are configured as BSP_EVENT_KEY_0.  I noticed people pushes the button between 0.2s to 0.4s after each click and the nRF52832 is not detecting the second click and the button has to be pressed a 4th time.

The IRQ prority is already at 2. I´m not sure if I should put it higher. My guess is that something in the main has higher priority and it is ignoring the bsp event

The only problem i have is when the device is sleeping. When the device is advertising the interruptions work fine. Any idea what is happening?

Here is my main, 

 

int main(void)
 {
    bool       wakeup;

    ret_code_t err_code;

    log_init();

    // Initialize the async SVCI interface to bootloader before any interrupts are enabled.
    err_code = ble_dfu_buttonless_async_svci_init();
    APP_ERROR_CHECK(err_code);

    timers_init();
    buttons_leds_init(&wakeup);
    my_fstorage_init();
    if(wakeup)
    {
        timer_counter();
    }
    power_management_init();
    fstorage_read(0x66C00,4);
    
    ble_stack_init();
    peer_manager_init();
    gap_params_init();
    gatt_init();
    services_init(); 
    conn_params_init();
    advertising_init();
    
    //saadc init
    saadc_init();
    saadc_sampling_event_init();
    saadc_sampling_event_enable();
    
    adv_init_and_start();

    NRF_LOG_INFO("GWi DFU Application started.");
    // Enter main loop.
    for (;;)
    {
        idle_state_handle();
    }
}

  • The BSP uses the app_button library who has implemented SW debouncing by setting an app_timer to trigger a callback after 50ms where the app_button library will check to see if the button is still pressed. 
    If the pin event is triggered before the 50ms has expired the app_button library will reset the app_timer. This might cause you trouble if the button signal is extremely bouncy. 

    I would scope the button signal to check for noise issues and log the button press patterns of good vs bad operations. This will give us valuable insight into how the application responds to the button presses.
