Lukas, thank you very much for your answer.

So there is no way to uniquely identify a Controllino device from within a sketch?

The reason why I’m asking is because we have put a lot of effort into the development of a sketch and want introduce a license mechanism to avoid that sketch is downloaded from one device and uploaded onto another.

I mean a sketch for CONTROLLINO.

For example on ESP32 you have a function “ESP.getChipId” or “ESP.getEfuseMac” which returns the serial number or mac address of the device.
