Mouse from ZMK not working

[Boggin]

I've a fork that I hadn't updated in a year: https://github.com/Boggin/zmk-config.

As part of getting up to the latest Zephyr 3.5 I changed to using the ZMK mouse. I've got something wrong, however, as my mouse layer won't work. I can activate the layer but I can't move, scroll or click. Instead the keys output as per the base layer.

I've tried checking my code against the main repo but I can't see any differences and everything else is working fine.

I've tried disconnecting from the laptop, removing the device, clearing all the bindings in the keyboard, adding the keeb back again. No joy.

Has anyone any other suggestions how I might debug my problem with using the mouse layer, please?

The mouse PR is still WIP and periodically requires updating the config to its newest api. If something breaks, it's worth looking closely at mouse.dtsi, the .config files, and going through the commit history to see if anything stands out (e.g., 6043e4b).

Other than that, some changes require refreshing the HID descriptor, which is often the culprit if nothing else works.

I had a similar issue on my linux laptop, refreshing the HID descriptor had no effect. When testing on my windows pc however, mouse movement & keys worked like a charm. Before the upgrade when using urobs ZMK mouse-3.2 branch mouse movement & keys worked on both my linux and windows pcs.

I have tried flashing the previously working version again and for some reason the mouse movement & keys are still not working on my linux pc.

Oh, and just to be sure, there were some changes in the mouse API about 2 months ago (which were pulled into the branch that you are using). One now must explicitly load the mouse_keys.dtsi header (in addition to mouse.h). See my comment above for details.

Nvm, just realize that it was you who had raised #52 in the first place :) Though, looking at your config I don't see the mouse_keys.dtsi header?

Yes, you don't see it because I've just pushed the temporary fix for the mouse-3.2 version. I'll try to get help on Discord and update if anything comes up. Thanks.

I just realized I haven't kept my config in sync with my firmware repo! Try 6043e4b

Yes, yesterday I found out that I needed the CONFIG_ZMK_MOUSE=y which must be mandatory now. But the issue now is that it only works via cable, but not working with BT even after profile clearing, keyboard reset, BT cache clear and trying other devices (still not Windows though).
I've went through the ZMK docs cause I'm still somewhat new to ZMK and tried a bunch of other system configs but with no success. Have any idea if something else is missing?
