I have an idea in mind that I am exploring. How could one communicate to multiple arduinos (or other similars like an ESP32) connected via GPIO?
I know the WiFi module is an ESP32, and I believe that it communicates to the Flipper via the serial connection. Which is fine for just 1 thing. But what about if I wanted to add another? When I take a look at the GPIO app and the USB-UART Bridge, I can see I can select the UART Pins to be either 13-14 (default), or 15-16. Can they both be used at the same time? And then what if I wanted to add more? How could I add another?
Taking a step back though, is serial really “the best” way to communicate to another microprocessor? Is there maybe a better way to do so? Or maybe an alternative (if not necessarily “better”) method of communication?
