Handoff/Continuity on my build?

I love my Hackintosh and the only thing that seems to be missing is Continuity features (such as Handoff, Apple Watch Unlock, and Airdrop). I have this Wi-Fi adapter and this Bluetooth 4.0 adapter in my system. The only one of these features that appears to show up is Airdrop, but my computer is undetected by any devices and my other devices can't seem to detect the computer. Is there any kind of kext or patch that could solve these problems for me?

Thanks for the help, I love this community!
