[Bluez-users] BD hardware address problem

[Bluez-users] BD hardware address problem

[Łukasz Hejnak]

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).

this is a known problem and it is these stupid ISSC dongles where the
manufacturer doesn't assigned unique addresses to each dongle. You can
try to use bdaddr from CVS to set your own address.

Hi, thanks for the fast reply, but unluckily that didn't help

szift@szift:~/blue/utils/test$./bdaddr -i hci0 22:22:22:22:22:22
Manufacturer:   Integrated System Solution Corp. (57)
Device address: 11:11:11:11:11:11
New BD address: 22:22:22:22:22:22

Can't write new address

But if I could give You any debug data that could be usefull, just let 
me know

and btw. Your web-based cvs viewer is down - I had to check the cvs 
history and guess to get the right module name ;]

of course it couldn't, I wasn't root ;]
after executing this set of commands
bdaddr -r -i hci0 22:22:22:22:22:22
hciconfig hci0 down
hciconfig hci0 up
I got the device up and going with the new address and the rest of my 
config, then I fired up:
pand -c 11:11:11:11:11:11
but now it ends with:
Connect to 11:11:11:11:11:11 failed. Protocol error(71)
and I'm stuck again ;]

use a valid BD_ADDR and not an address that will be a broadcast address
in the Ethernet range. Also run "hcidump -X -V" to see what is really
going on.
