Under "related" at right, the top item is how to get an Arduino to speak Bluetooth. Beyond that it's a matter of size and kind of antenna., and power of the radio stage (subject to legal limits). Personal guess if you're talking about 100 meters, I don't think watch batteries are going to do it.

Can't I Write A Program Telling Me The Range !? Cus that Sounds easy! To do. So do u have Any suggestion !? ..
No. The hardware doesn't have that capability, and without it the software can't do a darned thing.
I'm not sure the Bluetooth support even reports signal strength.
