I plan to make a RetroPie gaming station using 8BitDo bluetooth controllers, and I need to know if i need to spend extra money on bluetooth adapters to support multiple connections for multiple controllers.
Some devices cannot support it and some others can, and so for the sake of my small budget, i would like to know if i would need to buy more adapters, or just have the controllers and the pi.
(If this is not clear: I need to know how many devices/controllers can connect to the Raspberry Pi 3's on board bluetooth).
