The StateChanged signal is an "global" signal that emits the core NM
state.  That state is a composite of the state of all device managed by
NM.  The best approach here is probably to just query NM for the device
you care about, and monitor the device's signals for state.  Or, you can
listed for the global StateChanged signal, then ask NM for each device
object and each device's state.  If you end goal is simply to figure out
whether a specific network interface is 'connected'  or not, I'd go for
the first option: listen for state on the device(s) you care about.  The
"global" bits are more for email/chat/web clients that just want to know
"am I online".

http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python

has some python examples, including 'nm-state.py' which explicitly
queries each device's state.  You'd basically do that when you get the
StateChanged signal.
