I has an issue with BCM94352Z.
all working expect turn on/turn off.
when I turn off bluetooth, it always shows "on" and disconnect all devices, then cannot turn on again. need to restart pc to turn on it.
also some application using bluetooth to pair iPhone like Macid, Nearlock could not detect Iphone.
anyone please check your pc that it likes me ?
better is installing in S/L/EI can now use my bluetooth. what I did was installed my kexts in /Library/Extensions/ and removed them from my kexts folder in EFI.
my airdrop works also. but Nearlock not work.unfortunately I do not have those apps. but now when I go to finder and click on airdrop, it detects my iPhone immediately.
I think alsoI tried installing the nearlock app. it doesn't work as well on my high Sierra. but, I did try pairing a bluetooth earpiece and it was successfully paired. so I guess, it's just the app having issues.
Here is the my EFI working on 10.13 perfectly.
Main: H170N-wifi
CPU: i3 6100
SSD: OCZ NVME Rd400
Strix 750 TI
Wifi: DW1560
all iMessage, wireless, bluetooth, handoff, airdrop, power management... working fine.
