License of Bluetooth Stack for MicroC/OS-II

Hi everyone! As I know, Micrium has a third party Bluetooth stack called ClarinoxBlue. I would like to ask if it provides any free version for educational use?

I'm a university student and would like to implement bluetooth function in DE2-115 which currently using uC/OS-II.

I've tried to send email to Micrium regarding this but there is no reply. That is why I'm trying to post here. Hope it can help me.
