This sounds like a fun assignment. However, Bluetooth might not be your best option. Without any hardware (adapters or devices) there's nothing really for you to simulate.
For example, if you wanted to simulate wireless ethernet communication, you would do it over a wire. The protocol is the same, but the wire would simulate the wireless part. For Bluetooth, there's nothing to simulate. There's no hardware to simulate the Bluetooth communication protocols.
Maybe if I had a better understanding of what your assignment is I would be better able to help.
Have a great day!
