Hey
I have a brand new NUC and found out that the overall power consumption will raise about 2 watts if I keep bluetooth adapter on but turn off my paired bluetooth devices (keyboard+mouse).
If I keep them turned on power consumption of the NUC is permanently 2 watts lower.
Did I miss something to configure to avoid bluetooth adapter from wasting energy when there is no paired bluetooth device to be found?
I measured the power consumption with an energy meter to plug in.
Thanks in advance!
