Slow file transfer in Karmic compared to Jaunty version

[Subin Sebastian]

Binary package hint: gnome-bluetooth

Device I've : Nokia 7210 Supernova
Average file transfer rate in Jaunty (I think the gnome-bluetooth version is 0.11.0) was : 190KB/s
Average file transfer rate in Karmic (I think the gnome-bluetooth version is 2.28.0) is : 30KB/s

Err...seems to so slow...right?

Hello,

You know speed may vary, depending on the environment.

However, could you try the following:
- Open a terminal
- Type /usr/share/doc/obexd-client/examples/send-files XX:XX:XX:XX:XX:XX your-file
where XX:XX:XX:XX:XX:XX is the address of your device.

and try to evaluate the speed of the transfer.

Thanks

Tested send-files and had the same (slow) results.

Tested on Karmic and Lucid.

Average speed (taken from the GUI) is around 21/22kb

Please let me know how can I help with the troubleshooting.

Thanks

Same thing here on Lucid, 30KiB/s
Sony Ericsson K770i -> eeepc 1000h

Hi all, has there been any progress on this or a workaround found? I'm building a service in which users upload images and it's painfully slow compared to Windows with the same hardware (google nexus or any other phone -> Mac mini running Ubuntu 9.10 or Windows).

ok, this problem seems to be fixed in 10.10. Ma be a fix in blutooth applet.

Well in lubuntu 10.10 it is still slow, it slowens down to bytes and increases upto 30Kb but not more, only for the first file I have seen 180KB rate but not for others when sending multiple files

Another case verifying slow bluetooth on 10.04 and 10.10:

30KB/s on Dell m1530 laptop Broadcom BC2045 bluetooth card transferring to Nexus S.

FWIW, a few lines from the /var/log/btmp file (didn't help me at all):
