Yeah, sounds good. As far as choosing the actual address goes, I got
around to reminding myself how to generate proper link-local MAC
addresses. Seems that turning the universally administered
Bluetooth MAC
into a different link-local MAC usable on the USB interface would
be as
simple as to flip the second least significant bit of the most
significant byte into a 1¹. This would give us Neo-spesific static
That sounds pretty simple - and IMHO the probability of conflict is
as low as the number of Bluetooth devices out there...
link-local MACs in the simplest possible manner, and will allow us to
easily tie together the BT and USB MACs also from the host side, if
desired. How's that sound to you?
As an aside, last night I wrote up some suggestions on how to deal
with
USB network IP and routing settings in the final product, with use
cases². You're welcome to add your own input to the wiki, if you have
any; that's what it's there for.
