Hi @bking, you might remember [this](https://discourse.processing.org/t/program-slower-when-i-send-data-to-arduino/19815). Data was coming from the Arduino, and we used a character to Arduino as a data request. That’s data going both ways. If you wanted to use the request as well as other data, you’d have to use logic in the Arduino to separate one from the other.
