For the past few days I have been trying to figure out how to get a buffer of char sent from my nucleo to my Arduino.
The Arduino does not ask for information the nucleo should tell the Arduino when the buffer is full and then send it over.
I have asked on the Arduino forums with no luck. Has anybody done this before? If so could you show me? I am happy that my mbed code is working as it should it is the Arduino side that is difficult.
