I've also tried the blueZ driver, however the phone>PC
direction using OBEX was still only max 20kbyte/sec (at a
distance of 1 meters, DH5 packets were listed at pkg_config).

How could we debug what is causing this slowdown? (where is
the narrow part of the channel..)

Can anyone give some figures for Phone>PC transfer rate
using OBEX?

Is there any other (faster) option to transfer files from
phone to the PC?

I'd be really grateful also, if you could point me to a
manufacturer of some _serial_ bluetooth modul (just a
module, not a complete product), which can do fast OBEX
transfers...

Best regards,
Surf
