Needs a patch to IOBluetoothFamily. See my u430 config.plist: https://github.com/RehabMan/Lenovo-U430-Touch-DSDT-Patch

still not working

still not working

You must have done something wrong. Note that there are two patches... one for 10.10 and another for 10.11.

I've used the 10.11 patch

I've used the 10.11 patch

No idea without seeing ioreg and config.plist.

Also show "System Information" -> Bluetooth.

Make sure IOBluetoothFamily is 10.11 vanilla.

Use the 10.11 installer to refresh all your kexts (install without erasing).

I have Airport 14e4:432b. In Yosemite I managed to load Kext BCM 4360 but after upgrade BCM 4331 is loading only. I used in yosemite fakeid to load 4360.

Is there an way to force the 4360 to be loaded with my 14e4:432b card?

I have Bluetooth device BCM20702A0 and using 10.11. I tried each of the following (alone):

BluetoothDevInfoInjector by EMlyDinEsH
BrcmBluetoothInjector.kext by Rehabman
BrcmPatchRAM2.kext and BrcmFirmwareData.kext by Rehabman (together)

In all cases the bluetooth started to work. It can scan for discoverable and enabled bluetooth devices (although very slow) but it cannot pair with any one it finds. In addition, once the system wakes from sleep the bluetooth stops working until I restart. Does anybody have a suggestion to fix this? Thanks.

I attached IOREG for my system before and after sleep while using BrcmBluetoothInjector.kext.

Use BrcmPatchRAM2+BrcmFirmwareRepo.

And your problem after sleep is a USB problem, not bluetooth.

ahmed_ais · October 3, 2015

Use BrcmPatchRAM2+BrcmFirmwareRepo.

And your problem after sleep is a USB problem, not bluetooth.

Thanks, this fixed it along with properly patching my DSDT to fix USB issue.

sebinouse · October 6, 2015

Use BrcmPatchRAM2+BrcmFirmwareRepo.

No more BT issues for me with only BrcmPatchRAM2.kext.

What is the purpose of BrcmFirmwareRepo.kext ? Is it a place to store some FW that are not present in stock system ?

Anyway, thanks a lot for your work : anytime I use your files, it just works ! that's impressive !

robi39 · October 8, 2015

No bluetooth device on the USB bus in this ioreg. Likely USB problem.

All right still having the same problem, Bluetooth shows up but doesn't recognize any device, only if I boot in Windows first, which indicates firmware not loading problem, even updated firmware in windows, using BrcmFirmwareRepo and BrcmPatchRAM2 kexts.

I attached my ioreg file.

Do you know how I can fix that?

Compare firmware loaded with Windows vs. BrcmPatchRAM.

robi39 · October 10, 2015

Compare firmware loaded with Windows vs. BrcmPatchRAM.

Yes that is the problem, WIndows loads firmware v14 c5575 and BrcmPatchRAM loads firmware v14 c4096, how can I have BrcmPatchRAM load the same firmware?

You don't have BrcmPatchRAM installed correctly.

robi39 · October 16, 2015

You don't have BrcmPatchRAM installed correctly.

That did it, Thank you, as soon as I installed BrcmPatchRAM in S/L/E, started working great. previously it was at Clover kext folder

Thank you so much for the help.

0b05:17cf is already in the kext. Make sure you install it correctly (read the README).

Your image shows BrcmBluetoothInjector.kext installed, not BrcmPatchRAM2+BrcmFirmwareData (as would be required in Clover/kexts).

lazzy · November 1, 2015

Thanks it works when i remove BrcmBluetoothInjector.kext installed, and put BrcmPatchRAM2+BrcmFirmwareData together in clover/kext

But why handoff doesn't work?

i added in config.plist
