    Hi all,

    I have setup Simtools and added some example axis assignements. Then I setup the Interface as in the screenshots below.
    I have writte some basic Arduino code to respond with the data received or "..." if nothing was received.
    Somehow I am getting no Data to the Arduino.

    HELP PLEASE?

    Because you can't have SimTools and the serial monitor connecting to the board at the same time.

    Try to disconnect simtools and send something with the monitor for testing

    sometime you have to flush the serial port before be able to connect again with another software

    Could you explain how to flush the serial port, I am also having issues with getting data from Simtools into Arduino > Tools > Serial Monitor. It's just empty. Sometimes when I start up Arduino, and then Simtools and then start Output Testing, and then go to Arduino > Tools > Serial Monitor, I can actually see some data. But as soon as I open it the data stops flowing...

    Ok, I will try this (since I am having the same issue). But what data should I be sending? Is it in the format what I put in my "Interface Settings > Interface Output"? For example: R<Axis1a>~L<Axis2a>~

    So I should send data like so: R120~L90~
    ?

    It's very difficult to debug my code without being able to get data directly from Simtools while Serial Monitor is opened :(

    Ok, so it appears that I can just send data via Serial Monitor like so: R120~L90~
    Thanks a lot, now I can continue with my project :)
