yes, but because I also need to monitor VPN changes, I have to monitor /o/f/
NM.

This is, what I did before NetworkManager's PropertiesChanged signal got 
deprecated.
My problem is to understand, what path and what interface I have to use in 
this part of my code, after the PropertiesChanged signal moved from 
NetworkManager to DBus:

my $busobjpath = "org.freedesktop.NetworkManager";
my $busif = "org.freedesktop.DBus.Properties";
my $oBUSIF = $oBUSSVC->get_object( $busobjpath, $busif ) || die $!;
$oBUSIF->connect_to_signal(
  "PropertiesChanged", sub {
    &{ \&onPropertiesChanged }( @_ )
  } || die $!;
}

The original code now tells me

no signal PropertiesChanged in interface org.freedesktop.NetworkManager at /
usr/lib/perl5/vendor_perl/5.32.1/x86_64-linux-thread-multi/Net/DBus/Binding/
Introspector.pm line 420.

which seemed clear to me, because it got deprecated.


Thx and bye.
Michael.
