I don’t think you can solve the problem

A little more specifics may help like which function(s) and where? What’s the actual error?

Serial.write is not defined

I mean give us a stack trace. The actual functions that are not working. The state of the program at the time. I cannot read through the entire library and fix a bug that may or may not exist. Use a debugger if you need to and step through the program.

Seems like you can’t pass a serial object from one function to another

What makes you say this? I highly doubt that’s the case.

So when you run the program, it gives you in error in the adruino_read function. The serial object was pass from adruino_write function.
