Have any of you messed with Bluetooth to Arduino/ESP32 communication? I’m building an app on MIT App Inventor that has three buttons and three sliders sending info the ESP32. The problem I have is that I need to send six different sets of info, but the sliders all send 0-255 and the buttons could be anything. What is the proper way to send packets that the ESP32 an differentiate what slider is sending the number?
I set the App to send different groups of numbers and then mapped them in Arduino back to 0-255, but it seems like a hack.
