Q: Can I update my macbook pro early 2011 to use bluetooth 4.0

Oct 20, 2014 2:11 AMby James Reid1,Per my earlier post:
The correct chipset that you want is #BCM94331PCIEBT4CAX. Note that the chipset without the C (BCM94331PCIEBT4AX) will NOT improve your situation. It's the one already in the 2011 MBPs.
When searching on eBay, watch out for sellers who are offering "...2011, 2012..." compatible chipsets. These are invariably the older Bluetooth version.
I found only one seller who apparently has the correct chipset. Here's the link:
New MacBook Pro A1278 A1286 A1297 Unibody AirPort Extreme Card for 2011-2012

Oct 20, 2014 10:26 AMby .shepard.,Hi guys,
for those people that didn't modify the kext file yet, I wrote a script in bash that do all the stuff. It's also useful because probably we'll have to do these steps each time that Apple will release an update. The script saves automatically a copy of the original kext in the same folder of the script, so if something goes wrong you'll be able to return to the original situation.
This is the link to download it: https://mega.co.nz/#!rkYGwRAK!2w8OpwZZMyAuX-YL_piagmaGKhKretpjzxh9rcmTrCE
1) Open terminal
2) write: sudo nvram boot-args="kext-dev-mode=1"
3) reboot
4) open terminal and type:
cd Downloads/ (or the folder in which you saved the script)
sh patch_wifi
5) Reboot.
I tried this script with a MacBook Pro 2011 and I hadn't problem.

Oct 20, 2014 1:44 PMby SparkyC1984,I have read a lot of this thread but not all of it. (Sorry if this has already been covered)
But if possible can someone Please explain how my bluetooth chipset Broadcom 2070B0 in my MBP isn't compatible to work with handoff etc?
To my knowledge this chipset is capable of version 4.0 which is the highest version of bluetooth available unless I am mistaken? I fail to see that Low Energy Support is the problem here? surely these features should work on a Full powered device?
If I am correct then I see no hardware reasons why these features are disabled Just apple purposely disabling features so eventually people feel the need to splash out on a brand new Mac?

Oct 21, 2014 9:52 AMby James Reid1,Thank you. You are correct. If luis276 will refer to earlier posts, there is a link to an eBay seller that is selling the correct card. Please, everybody, don't go out and buy the "...AX" card when you need the "...CAX" card. You will go through trouble only to find that it doesn't work. Save yourselves the effort. There are good videos online about how to install. It's not terribly difficult.
If you've not taken your laptop apart before, like to replace the SSD or whatever, one tip you should attend to:
Take a sheet of typing paper. Draw a matrix on it of about 12 squares. In the center of each, afix a loop of scotch tape. As you take apart the laptop, stick associated screws onto each loop and label: "Front" "Left Side" "BT Card Bracket," and so on. Then you will save yourself the pain of putting screws into the wrong position, which can cause problems like pushing your keyboard up when your re-assemble. Do you suspect I write from experience? You suspect correctly.
Good luck! Buy the CORRECT card!
