Flyerrich,
What is the make, model, and age of your tablet?
It's an RCA Voyager from 2015, model RCT6773W42B.
Specs from RCA indicate that your tablet was built circa 2015, I think it is safe to say that the Bluetooth 4.0 from 2010 is included.
I bought a cheap RCA tablet earlier this year from Shopko, I think it too was a voyager but I am not at home to check compatibility with the app right now.
