also make sure your USB ports are configured correctly

The New Beginner's Guide to USB Port Configuration

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

I have updated the config.plist for you, u can see the changes yourself, it should be fixed for good.

1. Install Kext:
   1. Bluetooth: https://github.com/acidanthera/BrcmPatchRAM
   2. Wifi: https://github.com/acidanthera/AirportBrcmFixup
2. No need to modify any system kext
3. add a property to the WIFI card (change to your path)
   

   <key>PciRoot(0x0)/Pci(0x1c,0x3)/Pci(0x0)</key>
   <dict>
   <key>pci-aspm-default</key>
   <integer>0</integer>
   </dict>

4. See screenshot for clover config, get the path from hackintool.

Cant get Bluetooth to work on Catalina. According to Acidanthera the newest repo does not support DW1820a (at least it is not listed?!)
Patched my card as usual to get around the system hogging process (does not matter if these patches are present), added your little patch. Installed kexts in Clover:
AirportBRCMFixup.kext, BrcmBluetoothInjector.kext, BrcmFirmwareData.kext, BrcmPatchRAM3.kext

For wifi, you don't need other properties, just use the "pci-aspm-default", and remove the "brcmfx-driver=X" boot arg if you have.
For bluetooth:
In system information, can u get:
Firmware Version: v7 c4689
If you can, my method currently is,

1. Set the bluetooth USB port to USB 2.0 instead of internal
2. Sleep my laptop, wake the laptop
3. software unplug the bluetooth, (I plug it in VMware and unplug it)
4. then bluetooth is normal

• This has to be done for every sleep.

I don't know a better fix.
but disconnect, reconnect the bluetooth works for me.

Where exactly in system information? Bluetooth is empty and Firmware Version is not displayed in PCI.
Currently booting with USBInjectAll and PortLimitPatches to be sure.

Edit: Just to clarify I had the same card working on mojave on my XPS 13 9360. Now using it in a HP Envy 13 10th gen on Catalina.

I believe this method is for Bluetooth adapter with this card but not internal PCI, your method worked with me once and never worked again. not sure what happens - i keep testing this card but so far i got stable wifi.

There are no other changes except you removed brcm-driver=1 and change device properties right ? i gonna update to Catalina and report back. so far windows is 100% working driver=1 and other properties, mac side only Wifi and drops after few mints and system becomes slow af.
