Dongle Setup crash since commit 9e36ebd

[mryel00]

Hi, I've already written a comment in another issue, but I guess I open my own now, as I cannot 100% be sure that it's the same issue without further input of the other OP.

So basically there is a crash occuring in my Dongle setup with a nrf52840_mdk_usb_dongle, and two nrf pro micros (nice nano clones). It only happens if I use the dongle as a central device.

The bug appears since this exact commit: 9e36ebd
Any previous commit works just fine.

I can reliably trigger it when using a sticky shift and then hit my space bar that's using a mod morph nested inside a hold tap:
https://github.com/mryel00/zmk-config/blob/main/config/corne.keymap#L227-L238
Here are two other examples that crash it with just a mod morph:
https://github.com/mryel00/zmk-config/blob/dongle_test/config/chocofi.keymap#L48-L60

When it crashes, I need to reset the dongle and the splits, and the last input I have pressed is getting spammed till the reset. E.g. in the first example, it would be a . and in the second example the spc_morph2 it would be A.

If I should test anything, let me know. Thank you in advance for any help.

Does it also crash when you use USB (connected to central) without the dongle setup? There were reports of USB issues that sounded like this, that were modifier related.

I know this doesn't tie into the locality commit you pointed to. But if locality commit was the issue, I don't know why just adding a dongle would make a difference given that the keyboard was already a split.

Nope, just connecting it to USB without a Dongle works completely fine.
This issue is really weird, but I sadly don't know how to debug this correctly myself. Logging didn't log anything back then. I didn't look if maybe something useful is getting logged now, but I wouldn't think so.

I also read again through the Discord thread from here onward.
Seems like I misremembered the examples of my dongle_test branch. spc_morph2 is working fine. I will test the other dongle_test spc_morph hopefully soon (a lot of stuff going on right now in irl and my own projects 🙈), so for the moment I can only confirm that this one is failing:

Sry, for the misinformation 😓
