Vista - Bluetooth connects then immediatley disconnects

I have an HP DV9610 with Bluetooth and a Palm 700wx also with Bluetooth. When
I set up a pairing Vista finds the phone immediatley and the paring goes
smoothly. As soon as it's done, in Bluetooth devices it says connected then
immediately disconnects. This is repeatable. Whenever I go into the phone's
Bluetooth properties in the Bluetooth Devices app and exit , it connects then
disconnects. I have Windows Mobile Device center 6.1

I had Mobile Device center 6.0, but it wouldn't find the (WM5) phone even
via USB. I installed 6.1 and the USB sync works fine. Now I am trying to set
up the Bluetooth sync and a Bluetooh connection in general. With 6.0 I could
connect with the phone (storage card) but not sync. The connection was stable
and I could brows the phones storage, but now nothing at all with 6.1.

I decided to do a little more testing. I checked my Bluetooth GPS wiuth the
phone and it works fine. I then tried to pair the GPS with the laptop and it
behaves the same as the phone did. It finds the GPS immediately and then
installs the drivers, it connects then it immediately disconnects. If I go
into the propertied for it, it finds the avaiable services it provides. I
click on ok and it connects then again disconnects.

So it's definiately a problem on the pc. Since the GPS isn't a WM5 dvice it
shouldn't be an authentication issue. It seems to be something with
communication. Not sure where to go from here.

The GPS will still have a password. Mine does - Bluetooth version of
the Microsoft GPS device - the password is 12345678...

Double check with your vendor and see if you have a password for your
GPS.

It does have a passkey, that's not the issue. It connects just as the phone
does then 2 seconds later it disconnects. The phone has many things that can
interfere with Bluetooth. Camera. authentication and all. But the GPS is a
imple data channel device, no WM5 or anything, yet it behaves the same way.
So far everything points to the laptop, whatever it might be.

I mentioned the passkey because I get the exact same behavior when I
use the MS Bluetooth stack and have the wrong passkey.

When I enter the wrong passkey, it tells me so.

I made that mistake on the phone when I forgot to hit the cntrl key before
entering the numbers. So instead of entering numbers I was entering
characters.

t told me that I had entered the wrong passkey.

Mine just stopped working until I manually paired it again...

Are you using the MS Bluetooth stack or a third party one (Widcomm,
Toshiba, etc)?

It's the MS stack. I've had to do a complete image restore to factory spec
with nothing else on it. Bone stock.

Know what you mean...makes you want to tear your hair out. I changed (Vista) settings to disallow monitor to sleep and that solved 75% of the problem. However, monitor still wants to go to sleep at times in spite of settings. Then Bluetooth devices won't wake up. I keep having to go into the Control Panel using a wired mouse and "find" them.

I bought the Bluetooth keyboard & mouse for an XP OS computer in November 2007 and never had a problem. Got new (Vista OS) computer in December and it's been a nightmare since.
