I needed to receive a PDF file from a friend in a class. I use ubuntu LXDE (13.10) and my friend had a Samsung tablet. I enabled bluetooth. We went through some sort of "setup" and entered a security code and so and it seemed that this step was completed successfully. He tried to send me the file but I had no notifications coming up or anything and he got a "sending error" after a while. I searched for a "receive mode" or something but couldn't manage to find anything. I was able to send a file to him!

Even later I looked around quickly in unity but still didn't know how to receive files.

...how? :D
