Re: unable to create networkmanager proxy using glib

[satya gowtham kudupudi <satyagowtham k gmail com>]

i found out i can use gdbus. how to get signal strength? there isn't any method like getSignalStrength in NetworkManager gdbus object. 

nm-applet was able to display signal strength in system tray. so there should be a way to get signal strength form network manager!

nmcli is command line counter part of nm-applet. Can i get signal strength using nmcli? nothing about signal strength is mentioned in its man pages.

DBUS_BUS_SYSTEM here; NM runs as a root service on the system bus, not
the session bus (which is for user-specific processes in your login
session). The error you're seeing below means "NM not running on this
bus".  So try the system bus and I bet you'll get farther.
