Use BlueRetro as sender instead of receiver

[joselcl98]

Hello, I don't know if it could or will be another project that can, but I was going to make a hub for gamecube that would join the four controls with their original connector and connect to the gamecube by type c, it's a mini gamecube project that I'm doing little by little, but I was wondering if you could put an esp32 and a battery in that hub and you could invert the Blueretro function, read the data pin and send it to the console's esp32, or convert it to a generic standard so that other hubs of other consoles can be made and it is not necessary to modify the controller itself, damaging it along the way.
