probs with Bluetooth connection

[callymeiro]

I have a Orange (france) treo 650 but I obviously have problems with the Bluetooth connection. What I mean is that: I have a Parrot handfree set already included in my car (built in). After I paired my treo to the car, I am able to receive calls, and only receive them. As soon as the call is ended the bluetooth connection is disabled. Therefore I cannot consult my repertory from the car screen or call anyone directly from the car. I'm supposed to stop in order to make a call from my treo. I've tested the handfree set with a motorola V547 and it perfectly works. I figured out where the problem came from: the treo bluetooth connection is too quickly set to "sleep" in order not to use too much of the battery. The fact is that I'd like it NOT to sleep at all. I would like to activate the bluetooth connection and have it activated as long as I wouldn't desactivate it.
Any ideas?
