Title:
  Bluetooth disconnects devices regularly

Status in “bluez” package in Ubuntu:
  Confirmed

Bug description:
  My mouse suddenly disconnects randomly, while I am using it. Works
  fine for a while, suddenly it seems to disconnects because I can't use
  it, and then I press all the buttons, restart the mouse, or forces the
  Bluetooth  to connect using the Bluetooth indicator again, and
  suddenly it works again.

  Same thing goes for other Bluetooth devices. Using my Nexus 4 as a
  Bluetooth modem it's the same.
