Default [Q] Bluetooth Smart on Galaxy Nexus through rom?

Hi guys

I need to use Bluetooth Smart for a college project. However, I only own a Galaxy Nexus.
I've read that the device itself is compatible with 4.0, but the software is not.

My question is: does installing a custom 4.4 android rom enable the Bluetooth 4.0 capabilities? If so, do all of them, or only specific ones?

I have googled quite a bit about this subject, but there doesn't seem to be a straightforward answer.

Thanks in advance
