That does not have the bluetooth drivers yet, only the wireless drivers are working (Barely working. See the link about it). This still has some bugs that need to be worked on as mentioned in this Bug Report.
For the installation of that specific driver you can look at How do I get a Ralink RT3290 wireless card working? especially the part about renaming the file and editing some config files.
For the actual bluetooth there are 2 ways:
Wirama Web Solution
The following site did an extensive work on how to solve this issue, which points to a PATCH at the end in github. There is also a question regarding this issue in Ralink RT 3290 Bluetooth Problem on Ubuntu 14.04
Updating Kernel
You can also (This is risky and can have a lot of issues) update to the 3.15 or 3.16 Kernel. This 2 versions come with many bluetooth updates.
I would recommend the Wirama Solution until a proper solution can be found.
