it is the first step ;)

Actually I don't want to use the Affix code, because I don't like the
idea of using code that I don't understand. And at the moment I have
limited knowlodge how the Ethereal dissectors work.

However the Bluetooth H4 format is a standard definied in the Bluetooth
specification and my plan is to write a packet-bt-hci.c dissector that
can decode it. All other Bluetooth layers like L2CAP, RFCOMM, BNEP etc.
should be done by someone else. The HCI dissector is the important one,
because it can make it reusable for other Bluetooth protocol stacks and
my plan is to do it from scratch and not hacking the current Affix code.

Regards

Marcel
