Change your bluetooth device mac-address

You can download bdaddr here: bdaddr.
If you can’t get bdaddr installed to your Linux distribution BackTrack 4 has bdaddr on /pentest/bluetooth/bluesmash/tools directory. I installed bdaddr to my eeepc (running unbuntu) but I couldn’t change any bt mac with that but Dell Latitude D430 and Backtrack worked like a dream.

00:50:F2:7E:2F:9B My bluetooth dongle (old dongle from Microsoft keyboard/mouse)
00:01:E3:64:DD:9B Siemens Gigaset SL2 Professional Dect phone

First I scanned bluetooth devices around me:

00:01:E3:64:DD:9B aka SciptKiddie is my Siemens Gigaset SL Professional DECT phone.

Then I run bdaddr to see does it find my bt dongle:

Yep. Seems to work ok.

and now I change to my bluetooth dongle to same as my dect phone:

after that you have to unplug and plug in your bluetooth device.
after unplug/plug we can check our mac-address:

Yep. It’s changed to same as my dect phone. But I still wanted to test will it scan other devices:

Yep. It still seems to work perfectly.
