Folks, re: Bluetooth, I installed Mieze's latest drivers published at InsanelyMac. It's loading FW version 4689 and works great! I've finally recovered Bluetooth full operations with the DW1820A (#0VW3T3, 1028:0021) of  my 7490 running Catalina after caching the following kexts (from /L/E) from her latest V2.3.0d3 driver package:

  • BrcmBluetoothInjector
  • BrcmFirmwareRepo
  • BrcmPatchRAM3

I invite you all to try Mieze's drivers and let her know of your results at IM.

you got me all excited Hervé!!

 

Did yours become unreliable after a reboot or has it been powered on the whole time?

 

My problem came from rebooting to BIOS (never shutdown) to fix fan noise but after rebooting to BIOS twice it came back to macOS and bluetooth was unreliable... (before that worked for 3 whole days no problems!)

I don't have any problem with DW1820A Bluetooth/Wifi (everything is working), 

 

WIFI 2.4/5 Ghz: OK (fast connect)

BT: OK (connect good)

Personal Hotspot: OK 

Airdrop/Handoff/Continuity: OK

 

Used many hours but don't have any kernel panic or disconnect,

 

Sleep/Lid: Wifi/BT is work.
