Re: [Bluez-devel] Re: New HCI-USB device, no MAC?

[Nils Faerber <nils.faerber@kernelconcepts.de>]

Hi!
In case anyone else is interested in this issue too, as I said I
contacted ISSC about missing MAC addresses and after some mail ping-pong
got the following response. They really seem to care about the issue
now. I just still wonder what will happen.

So, here come the emails, starting with the last reply from one of their
managers:


"Dear Nils:

Thank you very much for your comment. First of all, ISSC is the one of
important BT IC provider. We also provide one robust reference board design
solution for our system customers. This reference design had passed BQB
certification to our system customers for class 2 dongle. In the reference
design, BT Address will be saved in the on board EEPROM. It's the unique BT
address with legal IVT software without exception. For products shipped with
EEPROM, BT_Addr can be changed through HCI command. However, for dongles
shipped without EEPROM, there is no place to store the new BT_addr. Anyway,
ISSC also believe this is a very serious issue, and we have also contacted
Bluetooth SIG to ask for their advise of this specific problems.
Unfortunately, we have not receive any response from them yet. As stated in
our previous email response to you, ISSC "ALWAYS" ship our IC with a legal
IVT software without exceptions. Unfortunately, some manufacturers went for
the extreme to save manufacturing cost at the expense of BT quality. I'm
including this message to Mike Foley so that he is more aware of this
problem. ISSC will do whatever it takes to solve this problems. By the way,
it is because ISSC's products has a very large market share, hence you see
most problems with our products. I can assure you that this problem is not
ISSC isolated instance. It is a problem that we will like to resolve as much
as you do, if no more than you do. For, this will hurt our BT industry as a
whole more than anything else. Regarding to your recommandation, if we can
change the BT Address through the HCI interface. Because IVT software is the
only one software interface between the User and USB BT Dongle. ISSC will
discuss with IVT to check if any solution for it soon.

 Thank you very much for your understanding, and let's see if we can come
out with a solution to resolve this issue.

Sincerely yours,
I.S.S.C./Sales Division
