Kinesis Advantage 360 Pro: F13-F24 keys do not work on Fn layer

[adamantine-dev]

Hi Nick!

Thank you so much for your project! It helps us a lot with configuring ZMK keyboards :)

Recently I have faced an issue when the F13-F24 keys don't work at all.

My Fn layer is:

I am using a MacOS system.
I tried to press those keys in System Setting, WebStorm IDE, and the following site:
https://www.toptal.com/developers/keycode

All of those places didn't trigger anything when I tried to hit newly added F13-F24 keys, while everything is good with F1-F12:
(info from https://www.toptal.com/developers/keycode):

• F1 is equal to 112 code;
• F2 is 113;
• ...
• F12 - 123.

Everything should be according to this table:
https://www.toptal.com/developers/keycode/table

So, according to it:

• F13 should be 124;
• F14 - 125;
• ...
• F24 - 135.

I could do something wrong, I am still new to ZMK configuration.

Please let me know how to resolve this issue :)

PS: is there any way to add F25-F32 keys?
I have never used them before, but it will be nice to play with them in IDEs HotKeys.

Hey, I think this is a configuration issue that a few Advantage 360 users have run into: https://zmk.dev/docs/config/system#hid (scroll down a bit to the NKRO usages info box).

As for the higher function keys you'd have to add them in ZMK itself first, but I take it they're not actually defined in the HID spec.

Thank you a lot!
Indeed, there is a mention in the main README file of my GitHub repo:

N-Key Rollover
By default this keyboard has NKRO enabled, however, for compatibility reasons, the higher ranges are not enabled. If you want to use F13-F24 or the INTL1-9 keys with NKRO enabled you can change CONFIG_ZMK_HID_KEYBOARD_EXTENDED_REPORT=n to CONFIG_ZMK_HID_KEYBOARD_EXTENDED_REPORT=y in adv360_left_defconfig:
your-repo-link/Adv360-Pro-ZMK/blob/V3.0/config/boards/arm/adv360/adv360_left_defconfig

Once I did it, it worked!
F13-F20 keys are available now.

However, the F21-24 keys still don't work.
Do you know why they don't work? Could it be some MacOS limitations?

One more interesting point: the new F13-F20 keys are working fine on my personal MacBook, but they don't work on my company's MacBook.
Could it be some additional security settings on the company's laptop?

Ok, thank you for the information.
Will read the documentation carefully to understand how to do it.
