I have same problem with bluetooth here, since Ubuntu 8.10 new (and fresh)
install until now, in sync with expeimental repositories
(for KDE 4.2, newest bt packs, etc, etc)...

I had changed my bt dongle (usb) thinking that are a problem with first, but
it was right and bt stack that wasn't (and sitll isn't) the problem...

I tried all kind of solutions, except kernel compile: 1. using experimental
repositories. 2. using alternative bueman reproitories, 3. downgrading
kdebluetooth4 to KDE 3.X, downgrading bt 4 stack to bt 3 stack, but noking
worked.

Curious, a cople of times, I get bt working for receiving/sending files from
other computer. Curious again, just for one or to times I get bt working for
sending files to mobeile (a1200), but not for receiving...

Oh, yes: Based on error message of obex-server, II had tried change
obex-server. I put obexd (work one time, neve more). Reinstalled
obex-server, or did a full remove of obex-server from my notebook fo them
install from source (manual compile and install)

But nothing! BT with a1200e still wont' work.

Any sugests that could I do?
