Realdash does not communicate with speeduino via serial 0

why doesn’t realdash communicate with the speeduino using serial 0?

We could not make it work and found no help for it :frowning:

I noticed that when connecting the speeduino to the Studio tuner it sets the communication as usb serial rs32, and realdash sets it as only usb serial, I believe if it were possible to complement realdash with the usb serial RS32 communication method, it would solve the problem of not communicating with serial 0.
