[Bluez-users] Bluetooth parings on dual-boot

Hi,
 
I'm having a problem with my dual boot laptop, and my google skills seem
to be failing me, was wondering if anyone had come across this before or
had any suggestions.
 
The laptops are dual booting XP (sp2) and SuSE 10.2 ( 2.6.18.2 kernel,
bluez 3.7.14)
 
The phone (Nokia 6680) pairs and work correctly for dial up networking,
but once it has been paired for use under XP, it has to be repaired
under Linux (and vice versa). 
 
The laptop has a different Bluetooth hostname under XP and SuSE, but the
problem still occurs. Is there anyway round this, or am I going to have
to do this due to the same Bluetooth MAC of the adapter in the laptop?
 
I've also used the same key when pairing the phone under XP and SusE but
again the problem occurs. 
 
Any suggestions etc gratefully received. 
 
Thanks
 
steve

Hi Steve,

This problem happens because the hcid returns the stored link key.
It is basically the same problem that I reported in the item 6 of
BlueZ TODO list:
http://wiki.bluez.org/wiki/TODO

Just remove the stored link key and pair it again.

$dbus-send --system --type=method_call --print-reply --dest=org.bluez
/org/bluez/hci0 org.bluez.Adapter.RemoveBonding
string:aa:bb:cc:dd:ee:ff

or

remove the remote device entry from the file=>
/var/lib/bluetooth/aa:bb:cc:dd:ee:ff/linkkeys


BR,
Claudio.

is there a workaround for this problem so the pairing doesn't have to be 
redone? like changing the adapter to use an alternate bdaddr inside 
linux so the phone thinks it's a different device?

Hi brad,

I've found a workaround, I installed bdaddr from the bluez-utils source
(it wasn't included in the SuSE rpm) which you can use to change the MAC
address of the bluetooth device:

 ./bdaddr -r -t -i hci0 NE:WM:AC:AD:RE:SS

Putting it into the init script seems to work a treat.

Cheers

steve
