BCM9435Z Bluetooth issue

[dodvip123]

Hi

5Ghz, bluetooth, handoff, airdrop are all working for this card but i encounter a small issue sometimes.

It seems like 1 out of 5 times when the laptop wakes up from sleep, bluetooth fails. There is ~ line through the Bluetooth icon in the status bar and i have to reboot to make it work again.

Is this a known issue? maybe a solution available?

Thanks in advance

Looks fine... did you disable "wake for BT" in SysPrefs->Bluetooth? Also "Wake for network access" in SysPrefs->Energy Saver?

"Wake for network access" wasn't disabled, will update if the problem persists or goes away. Time will tell, thanks!

Occured 1 time on booting, will update if it occurs another time

You should check your system.log for BrcmPatchRAM logs.

Disabling Virtualization in BIOS seems to help, haven't encountered the problem since.

Edit: never mind, it still happens

I think it's caused by usb port limitation.
Do you guys disabled ports that are exceed the limitation?
Bt part of 94352z needs a usb port.
