[Bluez-users] BD hardware address problem

["Łukasz Hejnak" <blue@szift.org>]

Hi
I've been trying to make a bluetooth link between two computers, a 
windows run laptop and my linux box - using two bluetooth usb dongles

The devices see each other (hcitool inq) but I can't get them connected 
using pand:
Jul 16 18:55:20 szift pand[5200]: Connecting to 11:11:11:11:11:11
Jul 16 18:55:20 szift pand[5200]: Connect to 11:11:11:11:11:11 failed. 
No route to host(113)

I think the problem is quite obvious: they both have been assigned the 
same bd address: 11:11:11:11:11:11
whatever I try, both devices still have the same bd addresses leading 
even to a situation like this (when connected to the same PC):

So I guess no wonder why pand didn't know which device I've been talking 
about when I typed 11:11:11...

Apart from this, both devices work fine.
I tested them with my nokia 6310i to get a gprs connection and it works.

So my question is:
is there anything I can do to change those bd addresses?
or is there any other way to get the connection up and going?

*My target is to share an EDGE link from the windows machine via these 
bluetooth adapters to my linux box*

I use bluez libs/utils 2.25 with a 2.6.16 kernel
The windows is a XP home with the drivers that were shipped together 
with the dongles (that side also works fine with the phone).
