Hello. Ive got google Chromecast..

Is there a way to find the version of the physical cast I plug into the Tv ? 

ive been to the "home" app on my mobile phone but cant determine if its the HOME software version,  or the physical device ?

Ive turned on bluetooth on my phone - (& wifi), but cannot determine / see if the chromecast has bluetooth. 
(I currently do not have a separate bluetooth device but want to know if its capable to turn on. )
