Can't send file to smartphone via bluetooth in Lubuntu?

I'm a new Lubuntu user (never used any Linux OS before).

File Manager --> Preferences --> Bluetooth Manager

I can't seem to send a file to my smartphone. I click the bluetooth icon on the task bar, a window comes up showing my smartphone.

Clicked "Pair" to pair my laptop and smartphone. Once paired, the Send File button is activated, meaning I can already send a file. So I choose a 36MB .mp4 file, then send, then:

Request timeout Error occurred while sending file video.mp4

First I thought it was because I'm using a custom ROM on my smartphone. But I switched to Windows 7 and was able to send the same file with no problem whatsoever.

Any ideas?

Solution 1:

This happens because Ubuntu and its derivatives (like Lubuntu) have a bug on the bluetooth stack. On the same link it suggests using blueman (sudo apt-get install blueman) for all your bluetooth needs. I have Ubuntu 12.04 and Bluetooth was very buggy.
