Mac OS X Wake Up from Sleep every single minute due to Bluetooth

My Mac OS X 10.10.3 - MBP 15" (Mid 2015) keeps waking up from Sleep, I've nailed down the cause to Bluetooth being ON, not even with devices paired or connected, just by having Bluetooth ON in System Preferences will wake up the computer every single minute, even after the Standbydelay time when the computer has entered Deep Sleep or Hibernation, the recurrent messages I am getting on the console are:

At the beginning I thought it was related to Wifi due to the messages, but as soon as I will turn OFF Bluetooth the computer will go into deep sleep or Hibernation after the Standbydelay time and there will be no message, any idea what could be causing this problem? thanks
