Borked my Bluetooth DUN

For a while now, I've been using my Motorola Q as a bluetooth DUN modem for my Nokia 770 and Nokia N800. Last night, I upgraded the firmware on my Q. Now Bluetooth DUN to my N800 no longer works!

"Connection failed to phone Pinhead. Try again?"

After trying every setting - data call, packet data, phone wizard, unpairing/pairing, and even flashing my N800, I'm still dead in the water. I tried initiating the pairing from the phone and from the tablet. Same results each time. I decided to see if it was the phone itself and set up a Bluetooth DUN connection on my Origami UMPC. It worked! It's not my phone - must be a setting on my tablet.

The funny part: I can now browse files on my Motorola Q through the File Manager. I had problems doing that in the past. It's paired - it's just not dialing.

My current guess - Changing the device name and settings but keeping the same Bluetooth MAC address on my Q confused the N800. My next step will be to re-flash my N800 and NOT restore the backup from the card. Then I will see if that is the issue. I'll keep posting.

The Motorola Q is a smartphone running WM5, right?

I believe (and this has been discussed in various threads on ITT) that in later AKUs (service packs) for WM5, Microsoft in their infinite wisdom dropped support for the DUN profile in preference to PAN. See here for details. The DUN profile may return in future update, but don't hold your breath.

So, what are your options?

1. Go back to your previous phone firmware
2. Try and get PAN working on the N800 - tricky, as it's not officially supported and needs all kinds of scripts/hacks etc. Here's a bug 1195 in Maemo Bugzilla which deals with this enhancement.
3. Get another non-WM phone

I hope you can at least go back to your original firmware. :(
