I'm still seeing this issue with 16.04.
Running the rkfill suggested by some does not work:
rfkill block bluetooth rfkill unblock bluetooth
The only thing that works is running the following after the system resumes:
service bluetooth restart
Note that if I have rfkill'ed, then after I have restarted the service, I need to unblock again before the bluetooth will work again.
