Setting up my new CM3 - Help me Out

[luisito]

@luisito: 
If you do get the wifi adapter, I'd recommend not upgrading system packages as that broke the built in buttons for me-- it's great for upgrading other components, transferring games, backing up saves and making tweaks like setting up the no sleep full screen driver though.

I do have the WiFi adapter, but I would like to know about the benefits of a bluetooth adapter. 
With WiFi, I definitely can populate Scrapper.
However, with bluetooth, is it possible to use an 8bitdo controller?
