Apologies for the length of post, please bear with me. I have read all the MS BT > Widcomm BT guides I can find!

I have been using the MS SP2 Bluetooth stack for Activesync for quite some time now. However, I now need to use the headset profile. I am using an MSI bluetooth dongle and according to MSI (after checking my BD Address) I must use Widcomm 1.3.1 drivers.

So I did the following:

1) Uninstall all bluetooth drivers in device manager.
2) Rename by bth.inf file to bth.inf.old
3) Restarted and confirmed that the old SP2 BT drivers were not installed.
4) I then installed the Widcomm drivers (MSI drivers).
5) I then used device manager to ensure that the non-digitally signed drivers were being used.

This all seemed to go just fine, although my bluetooth device was not listed under the bluetooth devices (there was no bluettoth node in device manager). Instead I think it was under USB devices.

However, now when I try and pair my PocketPC with my Desktop I click on the "Pair Device" button (or whatever it was called) and then entered a code. I then entered the same code on my PPC. Whilst pairing the devices, the "Pair Device" button became greyed out. Then when it was finished the "Pair Device" button became enabled but the Next button did not!

The only way I could continue and select which profiles I;d like to register was then to press "Skip Pairing". I completed the pairing by doing this and selected to use the Active Sync service.

I then checked that the COM port used by this service was selected in Activesync. However,when I try and sync, nothing happens on the Desktop and I get a "Cannot connect" message on the PCC.

Any ideas what has gone wrong with my Widcomm installationa nd why I can;t seem to pair correctly?

TIA

Hello... It doesn't look like you followed our guide to change from Microsoft Bluetooth to Widcomm Bluetooth, but you shouldn't have needed to rename files.

Have you checked firewall settings to see if ActiveSync is allowed? Also, make sure the adapter is connected to a USB port, not a USB HUB, since power supply may be diferent with different devices.

I didn't follow your specific guide since it seemed to mention a different problem and a different driver.

I have now tried your guide anyway.

It was slightly better in that I was able to pair the device succesfully (the PC responded to the PPC entering a pairing code).

However it still didn't connect to active sync properly, in fact after following the guide and then trying to change COM port number in Activesync caused my machine to BSOD with IRQ_NOT_LESS_OR_EQUAL.

My machine has worked flawlessly with the MS BT drivers for about a year! Never get any BSOD or anything like that!

The funncy thing is that when trying to chage the driver for "Generic Bluetooth Radio" I can't actually find that device in Device Manager. Here is a link to an image showing what my device manager looks like BEFORE I install the Widcomm drivers. It also shows what drivers are available for my bluetooth dongle:

http://www.elziko.pwp.blueyonder.co.uk/linked/Bluetooth.gif

You see, no mention of "Generic Bluetooth Radio".

Once I have installed the Widcomm drivers I get two options of drivers, both named "MSI USB Bluetooth Device". One is signed and the other isn't. Natuarally I select the unsigned version. The strange thing is that once I selct the unsigned driver I loose all my entries under the "Bluetooth Radios" node in the device manager and my hardware now appears under the "Universal Serial Bus controllers" node (I think!).

Luckily I have a Ghost image of my system before I try all this and I have once again reverted back to this image.

I just can't figure this out! Its almost like I end up with a mixture of MS & Widcomm drivers or something. maybe if there was a tool to actually remove the MS bluetooth stack completely, that would help!

Any other ideas?

Have you tried removing the COM port created during the installation and manually creating a new COM port, while using the MSI drivers?

The listed procedure is safe, and you can switch between any drivers in the system by following that.

As for removing the MS stack - haven't seem any tools for this around...

Tried one more time. Before I was changing the machine name in Bluetooth settings. This time I didn't and I also created a new Activesync connection from my PPC. This seemed to make everything work.

Unfortunatly this only lasts until I next reboot my machine... one I reboot I'm back to square one and I'm unable to connect. After a while some sort of "unable to start bluetooth service" or something message pops up.

Any ideas about that? Perhaps I'm getting closer to sorting this out!?

Thanks!
