Weird WiFi/BT Issues with DW1560 / Catalina 10.15.5

Hi There !

 

I am having some weird issues with my WiFi + BT combo card. It is a DW1560. 

 

BT:

BCM20702A0:

  Product ID: 0x216f

  Vendor ID: 0x0a5c  (Broadcom Corp.)

  Firmware Version: v14 c5668

WiFI:

  Card Type: AirPort Extreme  (0x14E4, 0x19

 

This is running on a HP ce140na laptop with Intel i5-8250U. I have my USBs set up correctly with a SSDT, card is recognized, wifi and bluetooth function "correctly" - I have FaceTime running OK, can place phone calls from the laptop, handoff works, so does AirDrop, however:

 

1. Bluetooth mouse will occasionally pause for a few seconds - and then "catch up" to my movements, as if it freezes - but where I move and click it buffers and does it all at once afterwards. During this time, touchpad moves OK. 

2. Same mouse works very well with its USB dongle (MX Master 3)

3. Apple bluetooth keyboard works, but stutters like the mouse.

4. Sidecar will only work if my tablet is connected via USB-C cable and has wifi disconnected on the tablet.

5. I cannot "import from iPhone or iPad" - it inevitably times out.

6. I cannot join a personal hotspot - even though it is identified - it just fails everytime. (Enabling hotspot manually on the phone and joining manually on the laptop works)

7. iPad and iPhone sync OTA

 

WiFi works brilliantly and I have no issues with range, signal strength, etc. 

E/C/K/O folder contains:

  BrcmBluetoothInjector.kext

  BrcmFirmwareData.kext

  BrcmFirmwareRepo.kext

  BrcmPatchRAM3.kext

  AirportBrcmFixup.kext

All latest version. Removing either of these breaks either WiFi or BT completely.

 

I am running Catalina 10.15.5, and a MacBookPro15,2 SMBIOS. 

Mouse, keyboard, phone and tablet updated to latest software/firmware.

Many thanks in advance!
