I now realize that beginning with Android 3.0 (API level 11), Android-powered devices are no longer required to provide a dedicated Menu button 
Joystick Bluetooth Commander Version 2.3 now adds full compatibility with Android 3.X and 4.X
The menu that allows BT connection can be accessed though the added 'action overflow button' (red square)
some other devices have a different icon at bottom left
thanks for bringing this point to my attention, sorry for being GingerBread centric
The application has been tested and is fully operative on my son's 7" Samsung Galaxy tablet (jelly beans)
Thanks to Julian for his contribution
