thanks for the reply...
i might be wrong but im pretty sure the ESP32 i bought has bluetooth.. i'll double check the ebay listing.. i tried to get the exact same one as the person who made it work previously...
here is the video they made to get it working.. id ask that person if i could but it appears they arent active on their youtube page now...
i'll post the sketch below... i have the joystick connected to the corresponding pins at the top of the sketch so i think thats OK.. appreciate any insight..
