if you use multicast in a point-to-point connection, it doesn't mean
that it is a real multicast. So don't confuse higher level multicast
support with multicast support of the Bluetooth radio. If the baseband
doesn't support it, it doesn't matter what the higher protocols layers
support.

And you should really get yourself a book with the Bluetooth basics. If
you don't understand how the basics work, you have problems to
understand what are the limitations of Bluetooth.

Regards

Marcel
