Issue is the patchram function not initialising the Bluetooth chip correctly. BrcmBluetoothInjector.kext is required for conpatability with Catalina (but also works with Mojave). If you delete it, then it will not work.

Thanks credit to @headkaze for the updated brcmpatchram kexts for Catalina, which I am using as a base here. I have made some changes to the underlying code which I am still testing to deal with the patching issue. How Did you get your Apple Watch unlock consistently working (I have seen your other post but replicating those settings only enables me to unlock once). Also does personal hotspot via handoff work for you (clicking iPhone hotspot connection in WiFi menu without hotspot being on or phone connected via Bluetooth).

Yes, will see what I can do. Out of interest is Apple watch unlock or personal hotspot working for you? Those are the only things that don’t work now for me.

Hi all, have been playing around with the driver to see if I can get firmware upload in Mojave to work on my dw1820a without needing windows to upload the firmware. It seems to be working ok , but am still testing to see if it works consistently. Attaching the kexts if anyone else would like to try with their dw1820a. These need to be uploaded to /EFI/CLOVER/Kexts/Other. Make sure you don't have any equivalent kexts in /L/E or /S/L/E. Let me know if you have any success.

@muttonhead411 Hi - can you a share a link for the windows drivers (v4689) shown in your screenshot please?
