Is it possible to use sense edge mask on Sidewalk?

Hello,

Sorry for the long response time. I was away for some time, and somehow I missed this ticket. Is there any update on this issue?

Actually, sidewalks manage a few GPIO pins with their own GPIO module; see the configuration here. I am not sure if this is an issue from the NRFX level (need to test) GPIO API. Please let me know the update.

Kind Regards,

Abhijith

The sense edge mask description:

Mask of pins that use the GPIO sense mechanism for edge detection.
Pins not included in the mask use GPIOTE channels in the event mode.

github.com/.../nordic,nrf-gpio.yaml

The code is implemented in zephyr/drivers/gpio/gpio_nrfx.c

    /* If edge mode is to be used and pin is not configured to use sense for
     * edge use IN event.
     */
    if (!(BIT(pin) & get_port_cfg(port)->edge_sense) &&
        (mode == GPIO_INT_MODE_EDGE) &&
        (nrf_gpio_pin_dir_get(abs_pin) == NRF_GPIO_PIN_DIR_INPUT)) {
        err = nrfx_gpiote_channel_get(abs_pin, &ch);
        if (err == NRFX_ERROR_INVALID_PARAM) {
            err = nrfx_gpiote_channel_alloc(&ch);
            if (err != NRFX_SUCCESS) {
                return -ENOMEM;
            }
        }

        trigger_config.p_in_channel = &ch;
    }

Hello,

[quote user=""]Is it possible to use sense edge mask on sx1262 or am I missing some setting?[/quote]

Could you give us some more details on what "sense edge mask" means? I am not aware of this. I have asked this internally, and it sounds like something unfamiliar to us.

Kind Regards,
