Instable Bluetooth, audio stutter, random disconnects

Hi!

I'm having a problem with bluetooth. It's a bit unstable at moments and I can't find why.

My specs:
- GA-Z97-DH3.
- i7 4790.
- GTX 980ti.
- Apple Broadcom BCM94360CD - 802.11 a/b/g/n/ac with Bluetooth 4.0.

WiFi:
Vendor ID: 0x14E4
Product ID: 0x111

Bluetooth:
Vendor ID: 0x05AC
Product ID: 0x828D

I have 2 main problems:
- random disconnects from my bluetooth keyboard.
- audio stutters using bluetooth headphones (Bose QC 35's)

Audio is patched using AppleALC and Lilu kexts.
No kexts needed for bluetooth or wifi to work.

Any advices? Thank you !
