PIN Miracast
Dear @bberg you mentioned, that PIN is not supported. In our school we have a lot of MiraCast Devices and Gnome.NetworkDisplays finds them all (WOlfvision Cynap Pure, Legamaster AirServer II). It would be a great to use your wonderful piece of software in school, because other connection methods are difficult in schol, when you bring your own devices.
Thanks for your effort Johannes Almer
