Comment 31 for bug 1509334

heh, that wasn't very useful. Has nothing from network manager or bluetooth which is where we think we want to be looking.

The interface must have sniffing turned off.

Does sudo bustle-pcap include anything better?

Altnernate approach is we go from the other side and run "gdb plasma"
then after 10s (where everything else should should be stopped)
type "control+c" "bt" and we find where plasma is blocked and waiting

If that's a bit much, I'll install Kubuntu 15.10 in a virtual machine which won't have bluetooth - and poke it there.
