please see Iain's response :) i knew he would chime in :) thanks Iain!
and, yes, i suspected that it would be something related to mac
addresses on virtual ethernet interface. i do not have a copy of spec
handy, but i recall something about setting mac address to be the same
as radio's bd_addr. dont remember if it was a requirement or more of a
guideline.
in any case, i like Iain's suggestion to rewrite mac addresses on the
fly. i would have done it this way. also, i think, nap server should
just act as ethernet hub, i.e. forward everything everywhere. after
all, nap is supposed to be like local ethernet network :)
Hmm. Working like an Ethernet hub also means that every single hub port
(in our case every single point-to-point BT link) may transmit packets
from different source MAC addresses, that can't be equal to BT adapter
address. So or I don't understand your example, or something is wrong here.
btw, obtaining bdaddr is really easy. in 99.9% cases (where there is
only one bluetooth device connected to the system) 'hccontrol
read_bd_addr' will do the trick :)
Indeed. But general number of BT tools, daemons and their options just
making me sad.
i'm not sure how to read that :) there is, like, less than 10
bluetooth related daemons in total. each has, like, may be 10 options.
compare this to the number of options ls(1) has :) not sure what could
possibly make you sad here. if you feel that the documentation is not
adequate, please feel free to fix it :)
10 daemons is understood, as BT is not that simple and IP stack also
have many different tools. But anyway having about 70 defined and
undocumented arguments of hccontrol alone, one of which should be used
for such basic thing as getting local btaddr, are not looking so funny
for anybody who are not BT guru. May be writing of some man page with
some BT basics to cross reference that basic tools could help. Or just
better cross reference existing pages.
