WMI Docs or drivers for Linux LED control for NUC8i3BE/NUC8i5BE/NUC8i7BE ( Bean Canyon)

We are looking for WMI docs for Bean Canyon models.

 

Neither DKMS Linux driver ( https://github.com/milesp20/intel_nuc_led) nor Hades https://github.com/nomego/intel_nuc_led work.

Gen 6/7 WMI calls report unsupported, and new Hades command doesn't seem to be completely incompatible.

Doing some test on NUC8i7BE with the latest BIOS ( the same happens on NUC8i3x)

 

Commands 0x1/0x2 - returns 0xE1-function not supported, return ACPI buffer type length 152 bytes

All other command (0,3,4,5,6) - return ACPI 'integer' (0)

S/W control is enabled in BIOS settings ( and RGB LEDs are not lit when s/w control is enabled)

It is almost like either BIOS or firmware is not supporting new LED WMI properly (Revision 0.64) and disabled old LED WMI ?

 

System Details:

 

Ubuntu : Linux chroma64-studio 4.15.0-20-lowlatency #21-Ubuntu SMP PREEMPT Tue Apr 24 07:52:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

BIOS Version 0064 - BECFL357.86A.0064.2019.0213.1122

 

fwts wmi - seems correct:

Hello dessa, Thank you for joining this Intel Community. The information we have available for WMI for Intel® NUC products is the following: Use WMI Explorer* to Program the Ring LED and Button LED https://www.intel.com/content/www/us/en/support/articles/000023426/mini-pcs/intel-nuc-kits.html The steps described in this article should also work for the units listed under "Related products". We recommend running the latest BIOS updates. In the meantime, we will do further research about this request. Wanner G. Intel Customer Support Technician Under Contract to Intel Corporation

Open WannerG_Intel WMI explorer is windows application and doesn't help.

Were you able to confirm that any of NUC8i3BE/NUC8i5BE/NUC8i7BE LED functions work for Windows?

As mentioned above the latest BIOS and Linux was used for test and issue seems to be in firmware.
