We are using ESP-IDF (not Arduino Core / Arduino IDE). We don’t use setup() and loop() under ESP-IDF.

With ESP-IDF, we need to have a void app_main(void) and inside a while (1) if needed in your application.

Can’t figure out how or where the output is or goes. I added void setup(){} and loop(){{} which keeps the compiler happy.
So, is this incomplete, or am I missing someting – most likely I have.
