Thanks. ESP-Now may work.

Or you could use esp32 S2 instead of ch559. It is just theoretically possible and you would have to write esp32 S2 code, but I think it's doable. Well, USB part is not that complicated I think, but esp32 S2 has like 2 or 3 hardware uart. I looked at this but the selected dev board has the regular E...

I am in the early stages of designing an art project/display where a set of ESP32 dev boards attach to a main PCB vertically using the usb connection. I want all communication to go through the usb so there are no connections/wires to the pins. I know this is not the best option but I want a clean l...

Is it possible to have 2 or more ESP32s talking to each other through the usb on a dev board using one of the usb host chips such as the CH559?
