The Orico Bluetooth adapter is equipped with CSR8510 controller, Bluetooth provides 4.0 and is backward compatible. It looks unassuming from (like all small USB adapter), but works fine. The delivery included CD is of course not in use with Android. Plug adapters and after a few seconds the TV shows Android Bluetooth functionality on - Super !!
Quick keyboard and mouse trying to connect. The first attempt was immediately successful. Maintains the connection, no dropouts and about 7 meters no problems at all. Also not in keyboard-oriented games :-))
Summary:
Easy, no problems, works perfectly and reliably on TV androids. Therefore full asterisk.
