Yes I was able to connect a Blue Tooth Speaker through my MaxiSys Elite (Android4.4.4) but tried to connect to a Roku Smart TV and an older LG TV with a Screen Beam Mini 2 via Miracast in settings. The Maxi Sys Elite and the TVs saw one another and connected , but so far didn't see the screen of the Maxi Sys Elite displayed to the TV.
