Ok so I need to compare string something like that
accessoryConfiguration.driver.testButtonPin == bit_to_pin && dev->name == 'GPIO_1'

Hi Michael,

In the callback you can get the port number of the pin that trigger the callback by checking the dev argument. So in the Button_pressed() function if you add this:

printk("Port of the button: %s ",dev->name);

You can find which port the pin (s) is on.

If understand you write then

#definу gpio_0 11
#definу gpio_1 12
#definу gpio_2 24
#definу gpio_3 25

static void GPIO_EVENT(nrfx_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
        LOG_INF("screaming pin %d", pin);
        LOG_INF("low or high state %d", action);
}

main()
{
	    IRQ_CONNECT(DT_IRQN(DT_NODELABEL(gpiote)),
		DT_IRQ(DT_NODELABEL(gpiote), priority),
		nrfx_isr, nrfx_gpiote_irq_handler, 0);
        nrfx_gpiote_init(NRFX_GPIOTE_DEFAULT_CONFIG_IRQ_PRIORITY);
        nrfx_gpiote_in_config_t cfg = NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);
        cfg.pull = NRF_GPIO_PIN_PULLDOWN;
        nrfx_gpiote_in_init(gpio_0, &cfg, GPIO_EVENT);
        nrfx_gpiote_in_init(gpio_1, &cfg, GPIO_EVENT);
        nrfx_gpiote_in_init(gpio_2, &cfg, GPIO_EVENT);
        nrfx_gpiote_in_init(gpio_3, &cfg, GPIO_EVENT);
        nrfx_gpiote_in_event_enable(gpio_0, true);
        nrfx_gpiote_in_event_enable(gpio_1, true);
        nrfx_gpiote_in_event_enable(gpio_2, true);
        nrfx_gpiote_in_event_enable(gpio_3, true);
