Macbook Pro - Problems with Bluetooth

Macbook Pro 13 / late 2012, OS X Yosemite 10.10.3, Magic Mouse.

After a long sleep (3-8h) bluetooth stop working - doesn't see devices, can't be switched on / off. Helps re-entered to sleep for a couple of minutes.

Remove com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile not help. Reset NVRAM and SMC brought no results.

P.S. Mountain Lion 10.8.5 / Mavericks 10.9.2 / Yosemite 10.10.1 - no problems!!!

Each time to reinstall the system is not the way to solve the problem.

MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.3)

Seem to have the same problem. My work around is to execute this in terminal:

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

It's only a workaround and temporary solution. It's so annoying. Any information about the real root cause and a permanent solution?

I look at the power management too. pmset -g showed hibernatemode 0. I Changes it to 3 and it seems to solve part of the issue.

Can you check if it solve your issue too?
