Since I'm new to CM12.1, I use three Bluetooth devices and would lose their connections after about a minute or two., than I wold have to re-pair the devices.
To get around this in CM12.1, I did the following:
First make sure your Bluetooth devices are paired and connected
Select Lock screen, than
Select Smart Lock, than
If not done, create your Pin, than
Under Trusted devices, select the Bluetooth devices you want as Trusted.
