as long as you only have one adapter attached to your system, you have
attempts to run inquiry and paging at the same time. This is not working
out. You can only do one thing at a time.

You can do it by hand on a raw socket, but why would you? D-Bus gives it
to you nicely.

Check the Bluetooth specification. Every inquiry result contains a 3
byte class of device value.
