Input long press / double tap overlay generates both intermediate and final button events

Question

Hi everyone,

I’m working with a Zephyr input overlay where I define double-tap, longpress, and extra_longpress behaviors on the same physical button.

This is the overlay I’m using:

/ {
    aliases {
        we13rfsmdoubletap = &double_tap;
        we13rfsmlongpress = &longpress;
        we13rfsmextralongpress = &extra_longpress;
    };

    double_tap: double_tap {
        input = <&{/buttons}>;
        compatible = "zephyr,input-double-tap";
        input-codes = <INPUT_KEY_0>;
        double-tap-codes = <INPUT_BTN_8>;
        double-tap-delay-ms = <300>;
    };

    longpress: longpress {
        input = <&{/buttons}>;
        compatible = "zephyr,input-longpress";
        input-codes = <INPUT_KEY_0>;
        short-codes = <INPUT_BTN_0>;
        long-codes = <INPUT_BTN_2>;
        long-delay-ms = <1000>;
    };

    extra_longpress: extra_longpress {
        input = <&buttons>;
        compatible = "zephyr,input-longpress";
        input-codes = <INPUT_BTN_2>;
        short-codes = <INPUT_BTN_2>;
        long-codes = <INPUT_BTN_6>;
        long-delay-ms = <2000>;
    };
};

Issue:

I have a state machine that receives button events from the input subsystem.

When I perform an extra long press, the state machine receives both:

INPUT_BTN_2 / long press event
INPUT_BTN_6 / extra long press event

Similarly, when I perform a double tap, the state machine receives both:

INPUT_BTN_0 / short press event
INPUT_BTN_8 / double tap event

Expected behavior:

I would like the state machine to receive only the final interpreted gesture event.

For example:

Extra long press → only INPUT_BTN_6
Double tap → only INPUT_BTN_8
Long press → only INPUT_BTN_2
Short press → only INPUT_BTN_0

Question:

Is there any way to fix this behaviour?

Thanks in advance for your help!
