HI, I’ve been trying to deconstruct a huge ino file from one of my projects into separate .h files so I can reuse the .h files in other projects. I’m trying to learn more and more about C++ but at the beginning I’ve hit a wall. I’m separating all the serial comms code from one ESP32 to another ESP32…

Breaking ino files into .h files fails

Please post the ino file that is using the Comms.h file so that we can see how your are #including it

Where on your PC is the Comms.h file located ?
