Bug Description

Binary package hint: gnome-bluetooth

I cannot send files to my mobile (Sony Ericsson K800i) via Bluetooth. A mobile doesn't seem to know that something is trying to send a file to it.

While browsing a device I also can't create new files, getting an error:
There was an error creating the directory in obex://[XX:XX:XX:XX:XX:XX]/STH
Operation not supported by backend.

It can be somehow connected to Bug #294617, but I'm not sure.

OK, I can make it both work and fail.

Steps to reproduce:
0) Click on a Bluetooth icon, choose a device (You can set it up earlier) and choose "Browse device". It works like a charm.
1) Try to create a file, You'll get an error:
There was an error creating the directory in obex://[XX:XX:XX:XX:XX:XX]/STH
Operation not supported by backend.
2) Click on a Bluetooth icon, choose a device and choose "Send file..." - it stucks at "Connecting", displaying a yellow triangle indicating sth went wrong - at this moment sending files *doesn't work*
3) Click on a Bluetooth icon, turn off and on Bluetooth
4) Now try to send a file again (in the same way as in (3)) - now it *does work*

It seems this creating-file error has further consequences and it causes sending to not work until Bluetooth connection is restarted.

This used to work in Jaunty.

I can confirm the file send issue. But the workaround of switching bluetooth off and then on doesn't work for me. My mobile is a Sony Ericsson K320i.

I mostly get a progress dialog with simply yellow triangle. But at some point of time I got this dialog with some error text. Hope it will be useful.

Try to delete the device and re-configure it. I have this problem too but I think is caused by the update to karmic, I have deleted mi phone and re-configured and now works perfect.

This is NOT caused by update to Karmic. I did a clean installation.

And, by the way, I created a new device a minute ago and still result is the same - it fails.

Ok, then it is not the same error that I had. I'm sorry.

Just a comment.
I have same problem with Polaroid PoGo in Karmic.
This small printer accept JPEG data via Bluetooth with BIP. It works perfectly in Jaunty or Windows XP, but wrong output caused in Karmic.
I think my problem seems to relate this bug.

If some information is needed, please let me know.


I would prefer that you open a specific bug, where you state what is the problem precisely.



Could you test to send file in terminal using:
/usr/share/doc/obexd-client/examples/send-files <device address> <file>
and tell here it works the same way?

Thanks for your suggestion.
I tried my issue with latest Lucid but still no good, so I'll open new bug about the issue.

@Baptiste Mille-Mathias:
An error happens also when using a terminal:

I've tried to pair my N900 and a E71 with my Lucid x86_64 and i get "Impossible to associate". I see on the phone and seems that there isn't any bluetooth connection when try to pairing.

Well, this is not a fix, because it doesn't use gnome-bluetooth. But I think it can help people having this problem. What I did to make Polaroid Pogo work under my Ubuntu 10.04 64-bit installation is to replace gnome-bluetooth with blueman. Under blueman everything seems to work properly.
