Re: Re: [bluetooth] LMP and Software interface

    I realize that I may have made some mistaken assumptions.  Please excuse me
if I'm asking questions that have already been discussed.  I had assumed that
the primary goal of the project was to produce a bluetooth module (baseband + 
microcontroller + firmware + host interface).  But based on your comment about
choosing an OS and CPU, I see that I may have been incorrect.  Is the plan to 
create a baseband which will be manipulated directly across the WISHBONE bus
by the host controller, and including LMP, HCI, and all higher levels within
the drivers running on the host?  Or do you just mean that we should determine
what microcontroller and operating system to use to run just the firmware
functions?

    The work that I've done with Bluetooth has primarily been with BlueZ, which
is very heavily influenced by the PC world view of the bluetooth device as a
UART, USB, or CardBus device.  With the low level functions of HCI, link 
management, and baseband encapsulated within black box third party modules, I 
have unfortunately never had a chance to work a bluetooth system at the
register level you have specified.  I also don't currently have a resource I 
could draw on who has worked at this level.  There is some discussion going on 
the bluez developers list for a while about Bluetooth qualification using the
BlueZ stack.  Some of the people involved in those discussions seem like they
may have the necessary background to provide you with the feedback you're 
looking for.  Perhaps post some information about the project on that list.  I
would assume that something like a fully open bluetooth core would be the type
of project that everyone working with the technology would be interested in
seeing (but I'm know to be a bit over enthusiastic about open projects also :-)
