this is Bluetooth specific, so you should read the specification. The
underlaying data link is always ACL and there is also only one ACL link
between two devices. The L2CAP or RFCOMM connections share always the
same ACL link.

If you exit the program without closing the L2CAP sockets, the OS will
close it for you and this is the same as you close the sockets without
sleeping between it. Closing the ACL link is the job of the kernel.

Marcel
