I have used "hcitool scan" command but it can'nt find any address of other laptops but can detect phones . How can i connect 2 laptops ?
Make sure the other laptop is visible. Use the gnome or unity UI or if you don't have a desktop refer to this link- http://ubuntuforums.org/showthread.php?t=1530253.
You can also make an adhoc network and then share the files.
