bluetooth 2.0 is extremely slow

[Mike Cronenworth]

Hi all,

I've lived with slow transfer speeds long enough. Ever since I purchased
an ASUS Bluetooth 2.0+EDR USB adapter it has always taken *minutes*
instead of *seconds* to transfer files from my cell phone to my computer
and vice versa.

Fedora 8, latest updates.
Nokia N95-1, latest firmware.

Both are Bluetooth 2.0+EDR devices.

It took *40 seconds* to transfer a 1 megabyte picture. I timed this with
'watch -n 1 date' for grins, so I can't give you nanosecond numbers, but
even a rough estimate shows that transfer speeds are *abysmal* and need
to be addressed. Ideally it should be taking less than 10 seconds to
transfer the same image file on a true 2.0+EDR setup. I have two
different computers with two of the same Asus adapter. Same speeds.

I saw someone fixed this by forcing larger MTUs.

Before modifying the OpenOBEX sources, I posted a message on their
board, but I haven't heard anything yet. Does anyone have any experience
with this?

I have tried the fedora-list without an answer. Also, the OpenOBEX 
developers are silent on this. Is this because no one has a 2.0 adapter 
and 2.0 device?

Thanks,
Mike
