[Maik Zumstrull]

My exchange with Broadcom regarding chipset specs. They want "BlueZ" to
contact them directly. Not that you tried that or anything...

We do not provide such info to 3rd party developers. If Bluez is looking
for info so that they can use SCO on a Broadcom Bluetooth chipset then
BlueZ should contact us directly for such info.

Thanks for obviously not even reading my message.

I'm retrying with another contact address.

As you can read in my original message, which is included below your
automated reply, I would very much like to see the programming interface
specifiction for your Bluetooth chipsets released to the public; or at
least to the team developing the official Linux Bluetooth protocol
stack, BlueZ.

Thank you for your inquiry.  Broadcom Corporation acquired WIDCOMM Inc.
software, which was licensed to various 3rd party companies who bundled
our software with their Bluetooth devices. Unfortunately, some of these
companies inadequately left Broadcom's support information in the
software interface instead of replacing it with their own support
information.



Each of these companies customizes the software for their particular
Bluetooth device therefore  our off-the-shelf standard version of the
software would not work with most 3rd company devices. Please contact
the manufacturer or distributor of your device to obtain software
upgrades.



For your convenience we have gathered contact information for some known
OEMs of our software:



* Micro-Star International (MSI): support@msi.com.tw

* Acer: euro_help@acer-euro.com

* Tecom (BT3030): support@tecom.com.tw

* Tecom (BT3030) software upgrades, documentation, and other support go

Feedback:
Please release the complete specification of the Broadcom Bluetooth
chipsets to the authors of the BlueZ Linux Bluetooth stack. At this
point, important features, e.g. the use of Bluetooth Headsets, are not
supported by BlueZ with Broadcom HCIs because it is unknown how to
program the chips.



I have a broadcom HCI in my laptop computer, but need to use an external
dongle because SCO mapping can only be done with CSR HCIs under BlueZ at
this point. According to the developers, this is due to lack of
cooperation from your side.

Maik,

I don't think anyone would have a problem with you telling them you're
"with" the bluez group, but I suspect they're asking this way because
they want an NDA signed. That obviously wouldn't be acceptable.

Why wouldn't it? I would like to read it before judging it.

I think an agreement not to release any original Broadcom documents to
the general public would be acceptable, as long as they understand and
agree that the driver would be open-source and that therefore some
information would indirectly be published. Of course, I can only speak
for myself, other people might disagree.

In fact, that's pretty much what I suggested in a follow-up eMail. I'll
see what their position is. Broadcom has been somewhat cooperative
regarding open-source projects in the past, so maybe something can
actually be worked out.

Sure, it's true that there might be an NDA that would allow for a GPL
implementation. It's just unlikely :(

feel free to agree with Broadcom whatever you think is needed, but I am
not dealing with it. This is way too much politics for me and I actually
prefer to write good code. And btw it is not only Broadcom that isn't
really helpful. However they are the big player besides CSR, but did you
ever thought about Silicon Wave, Texas Instruments or Infineon. Non of
their chips have any special support so far and I can't advice anyone to
pick one of these to build an embedded device running Linux.

Maybe someone should point them to see how CSR is working with the open
source community. And I didn't see their chip sales going down, because
of it ;)

Regards

Marcel
