I think some or most of the problems have been ironed out during developement to pr1.3 or CSSU.

Performance with my Nokia BH-214 bluetooth headset is fine. Music sounds nice, phone calls and live meetings are ok. I am using CSSU testing so I cannot comment on the current situation with pr1.3.

I also have(had) one problem though, after every call I receive the headset doesn't switch back to A2DB profile for music. It seems BH-214 should do this change as it occurs also when I use it with my laptop for music and online meetings. On the laptop it ends up with music playing but sounding like something from the 60's. On N900 when the call ends music is played with 2 sec pauses and distortions.

So I disconnected from N900 with power off and on from BH-214 and it connects back and music plays fine.

But as usually happens now when I tried to reproduce this behaviour it works as expected. Maybe yesterdays CSSU update fixed something or the BH-214 just has a mind of its own. I tried a few calls to and from N900. Also tried ending the call on N900 and on the other end. I haven't tried the laptop connection though but I suppose most people here are interested in N900 and bluetooth.

And reading the last few comments I can add that I am also using kernel-power 49 and CSSU testing (21.2011.38-1maemo1.1). After yesterdays update it seems to work.

So happy to say it seems to work perfectly with N900 after all.
