Ever since i bought BCM943602CS with adapter a year ago, i was enjoying my build like a real mac - Handoff, Continuity, AirDrop, iMessages, Apple Watch unlock - all worked out of the box, but that changed when i updated to 10.15.1 a few days ago. While WiFi still works, Bluetooth stopped working. I read tons of forum posts but i still haven't fixed it. Been trying to fix it for a three straight days, almost fully dedicated to fix this problem. I restored to 10.15.0 with Time Machine, but even then Bluetooth was not working, but it worked on 10.15.0 before the update. After updating and restoring, Bluetooth icon on the top of the screen showed "Bluetooth: Not Available". Bluetooth icon from the Preferences panel was gone. When i did a clean install of 10.15.1, even Bluetooth icon with "Bluetooth: Not Available" was gone.
As i mentioned, i read a lot of topics regarding BCM943602CS bluetooth issues, but all of them were about users who tried to make bluetooth work when they just got the BCM943602CS with adapter. Some of them even found out that vendorID or productID didn't match a fully supported model and they bought another bluetooth cards. Very little of them managed to fix it and even then, they had to modify or load some kexts. As i mentioned before, bluetooth worked out of the box when i got the BCM943602CS. I checked my productID and vendorID, and while Vendor ID showed 0x05ac (supported vendor), Product ID showed 0xf007 - the one, i found on the forum, as being not supported one. Then why did it work out of the box before (for a year)? I checked my SSDT for USB, tried to connect to different USB headers and even outside ports - didn't make any difference. Tried different drivers to make it work at least on Windows, none of them where working. Windows detected it, said "getting ready", then that it was successfully added (i don't remember exact text), but under Device Manager it still showed under unidentified devices (don't remember how exactly was it written).
I have two guesses, one may be connected to this article of bluetooth issues since 10.15.1 even on real Macs:
https://discussions.apple.com/thread/250801271
Another guess is that 10.15.1 update somehow messed up BCM943602CS bluetooth firmware, thus i now get unsupported Product ID of 0xf007 (which was mentioned as unsupported on another topic).
Both of the guesses might be connected.
I bought this card with adapter here in late October, 2018: https://www.amazon.de/gp/product/B00MBP25UK/?tag=tonymacx8603-21 (photos of it now are different, mine has 3 antennas, this one has 2).
Thank you for you help!
EDIT! PROBLEM SOLVED
Thanks to @headkaze.
Cause: Bluetooth adapter firmware got corrupted during update from 10.15.0 to 10.15.1.
Solution is here.
