The command would look like {MOVE, 60, 70} or {REQUEST_DATA}, where I’d have the arduino read in the first value, if it’s "MOVE" then it drives …

Can you read from serial buffer without knowing baudrate? Question: I’m just wondering why it’s necessary to know the baud rate when reading serial data from the buffer with PySerial. Shouldn’t the byte data in the buffer be the same regardless of 9600 or 38400 baud rate, with the exception that the latter fills faster? …
