thank you for the update. tested it and it works 100%.

do you have any plans to commit upstream?

two ideas:

i actually don't like the idea of turning BT off when pyobd exits. i am surprised there is no resource subscribe/unsubscribe model in maemo? this means - you request BT and get it, then you release it and the service is kept on/off depending on other subscribers...
at least we should detect if BT was on/off before pyobd as turning it off is just a bad practice. i use BT all the time in the car for handsfree, if pyobd turns it off for me, this is bad.

i am looking for a dial widget in wxwidgets, so we could implement some visually appealing tabs in the interface, like speed/rpms/temp , do you know of any, or do we have to animate it ourselves via canvas/html drawing?
