Hi, Could you offer an example to show how to call the getVersion() method? With my very limited understanding of C/C++ I have tried this:

    String rev;
    Elm.getVersion(rev);
    Serial1.println(rev);        //Serial1 is not the UART talking to the STN1110

Which compiles and runs but does not return the correct string (it returns "OK" instead of "ELM327..."). My problem is that I do not understand the "(String& rev)" in the method signature. Best regards, Martin

Same, having issues setting the baud to 38400 instead of 9600. My adapter is default 38400.
