I have Ubuntu 12.04 LTS on my Dell Vostro laptop. I am able to send files over bluetooth from my PC to my Android mobile but not vice versa even though the two devices are paired.The file transfer just fails with " File Not Sent " message. The problem is the option to receive files is disabled in the gnome-file-share-properties of Ubuntu. To access this dialog open the terminal and type gnome-file-share-properties Please note that you might be able to change the property if you are using the dialog as a root user.You need to be a non-root user for this. You just need to check the option for " Receive files in Downloads folder over Bluetooth " and it is done.
