ok so I’m building my own Raspberry Pi console based on the design of a Nintendo Switch (features include a controller that is split into two parts and con connect to each other or the console, a dock for easy charging and HDMI out, and a Raspberry Pi running retro Pi.) First off let me address that I know this forum isn’t really for raspberry pi projects, but i figured I’d see if anyone could help me with my problem. Ok so my problem is this: I’m trying to Find a way to split my Bluetooth controller into two parts: one for the left side of the console and one for the right, while retaining the ability to detach the controllers from the console and attach them to each other to form a regular Bluetooth controller (sorry if that seemed convoluted). So to be more specific my first problem is splitting the controller My second problem is getting them to be able to detach from the console i was thinking that i could solder the buttons to a male USB plug on one controller and a female USB on the corresponding side of the console, running wires along the console to the other side, where a male USB will be connected to the console and a female USB connected to the other controller. This would allow me to plug the controllers into the console as well as into each other (since one controller has a male and one has a female USB), but the problem Is i don’t think i can do that since there are a total of 15 buttons on my controller and a USB cable only has two data ports. So i need help finding another way to attach the controllers. Any help is greatly appreciated!
