No, I dont. I do not have laptop, I have desktop dualboot with windows on it. The card is in combination with wifi - Half Mini PCI-E Card with no switches

Please try injecting the attached kexts from Clover/OpenCore. Remember to remove/disable your current Bluetooth kexts.

In kernel.log (after putting those kexts to /L/E) and cold boot (higlights):

Also I must mention, that in the past I had IOGear GBU521 usb stick - but its gone now.

No, please put them in /EFI/CLOVER/kexts/Other/. Do not put them in /Library/Extensions/.

Ok, I am dumbass. I did not connect the AUX antenna. After that I can find devices (surprice ). But it keeps them disconnecting. I'll try to move kexts from /L/E and put them to clover Efi. And rebuild cache.
Thank you pastrychef

UPDATE

I think I found the problem for the wifi/bt... I remove the card and on one side is 1820A on the other side ( when remove the film) the name of the card is other... BCM94356ZEPA50DX_2..... I attach the photo of the 2 side:

There is a solution for this?

@yota79,

As far as I know BCM94356Z Chipset is not supported in MacOS .... See the list of supported devices in post #1

Broadcom WiFi/Bluetooth [Guide]

Broadcom WiFi/Bluetooth [Guide] WiFi and Bluetooth working out of box on macOS with Apple branded Broadcom BCM94360. Enables specific half mini and M.2 BCM94352 on macOS with methods described below. Credit: RehabMan This thread does not support: macOS/Continuity Atheros/Qualcomm...

Looks like you've been sold fake hardware ....
A genuine DW1820A should have a BCM94350Z Chipset which is natively supported.

Cheers

I've attached the Broadcom BCM943602CS with the
m2 adapter https://de.aliexpress.com/item/33008569320.html on intel nuc7i7bnh.
Wifi is working out of the box. But bluetooth does not work. I think it is cause I have not connected the usb cable from the adapter card to the motherboard, cause I do not know how and where to connect it.
The motherboard has only one free front panel header and no free usb header. Any suggestions how to plug the usb cable from the adapter (only 2 pins D+ and D-) are needed

I bought 802.11+Bluetooth 4.1 Broadcom BCM943602CS wireless wifi Card For Desktops with mini pci-e to PCI-E 1X Adapter from https://www.aliexpress.com/item/32752631671.html?spm=a2g0s.9042311.0.0.44f44c4dEmDp7p.
It's work great with Catalina.

I don't know for sure because I have avoided Z390 boards, but the ASRock boards seem to support E-Key M.2 wi-fi in addition to CNVi.
