Conclusion: if you have a Broadcom wifi card (and if the clover continuity patch does not work- or work well - for you with the Broadcom card alone) then it seems to me to be worthwhile to spend a few pounds/dollars on a GMYLE BT adapter to see if it that combination will allow you to unleash continuity/handoff on your yosemite build. Particularly worth a go I would say if you have a ITX or a laptop build.
That's great news Minihack,
Just a question or two if you don't mind.
Did you have to do anything regarding the Bluetooth Firmware Uploader, or did you just patch in the code into your config.plist? (assuming you're using clover).
Did the Handoff/Hotspot support show once you initially reseted, or did it only say "Yes" once you signed out and back into iCloud?
This seems like a pretty good solution, as i currently have a Z77N-Wifi and an NUC, so, unless some magical half mini PCIe card starts doing the rounds, it looks like this may be the only solution.
A question to everyone or anyone who may know. Do any of the feature require "WIFI" / the presence of a Airport Card, opposed to an ethernet connection? As I don't really have a need for wifi as i've cat6'd all my machines to my AirPort Extreme, so only the iOS devices at home are on wifi.
If I could just get the compatible BT USB Dongle and not have to worry about getting a compatible AirPlay Card, that'd be a very nice outcome.
I've only tested it on my rMBP, by disabling wifi, and as far as i can remember, everything still worked, but i question how 'disabled' the card would be if it works in tandem with the BT inside the mac.
Im in the same boat as a lot of mITX users by the look of it. The GPU is our only PCI card and we aren't willing to sacrifice it for ultimate compatability.
Closest I've come is finding a half mPCI riser/ribbon card, which would potentially allow the OSXWIFI to mPCI (for Mac Pro) card to be fitted somewhere inside my Prodigy. I worry about the grounding of the PCB's though, probably incorrectly.
