I love this project, I’ve installed retropie today and played some games with the keyboard, added games, paired dual shock controllers etc. In short: a lot of fun!
Now, is it possible to pair my smarthphone with the Rpi and use it as a bluetooth controller? The idea is that when some friends come over, they just take there device, start an app that paires with the pi and launches the controller. I’ve searched a couple of hours but I couldn’t find a satisfying answer.
