Mark 1 Answers 0 Vote Up Vote Down Rui Santos Staff answered 6 years ago Hello Marco! After powering your ESP32 board, the sketch that you’ve uploaded to your ESP32 will automatically run/execute. If it’s an Arduino sketch, it starts by running the setup() code first. Then, runs the loop() code continuously. Regards, Rui
