Yes, you have to find the device object path for your case. You can start with the following two options.
1. Use GetDevices, find the appropriate wireless device and then call ActiveAccessPoint on that device.

2. Get the ActiveConnections property. Get the devices that are part of this active connection (Devices property). You will get the wireless device object path. Then call ActiveAccessPoint on that device and get the Ssid property.

Please understand that Ssid is not a property of a network interface/device in your computer. It is not so complicated. Please find the python samples.

And after that I have to convert the array of bytes into a simple
string.

Man, I didn't excpect it such complicated. :)

Maybe I should stick with nm-tool and a bit of grep.
(iwlist or iwgetid isn't working for me, that's why I thought d-bus
could be my hero)
Thanks anyway for all your help, this is a great community!
