When bluetoothctl starts, it registers itself with the dbus with root path same as the bluez root path i.e. '/'. When advertisement monitor objects are created or removed, InterfacesAdded/InterfacesRemoved signals are emitted. These signals are emitted at the registered root path by default. However, these signals need to be emitted at the app root path registered using the "RegisterMonitor" method while registering the client app with bluetoothd. This patch adds support in the gdbus library to emit signals at the app root path.
