Just an update on this re: the Bluetooth.

I had my AirPods paired previously for single use. I don't use them on 
the laptop (there is some latency), so I prefer the wired earphones. But 
it seems like Bluetooth was aggressively scanning for them. After 
removing them from the system, the scanning remained, but reduced 

So looking at Console again, every so often, Bluetooth is scanning the 
network on behalf of the "sharingd" process.

sharingd is a sharing daemon that supports features such as AirDrop, 
Handoff, Instant Hotspot, Shared Computers and Remote Disc in Finder.

Still keeping Bluetooth off, however.
