I am using (IBM T20)PClinuxOS openbox mini with pcmanfm file manager and a Sony ericsson W995. I have found that installing blueman , bluez and their dependencies, with the addition of obexftp and libobexftp0, pcmanfm needs the last two items, works quite well.
Reboot and insert your bluetooth dongle, start bluetooth manager.
right click bluetooth icon
select local services
set folder to Downloads
tick the ‘accept files from trusted devices’ box
nautilus --browser obex://[%d]
It seems the order of recognition is important for things to work smoothly, first make your PC visible , in my case with the SE W995 scan for devices and pair.
You should be able to transfer files between devices now.
Works on my system, seems to be a step in the right direction , anyway.
May the weather be fair and the trout keep biting.
