No activity on serial monitor

Postby Seeker » Tue Jan 24, 2023 5:25 am

ESP32-S3-DevKitC-1U on Arduino IDE. Load program OK but never any serial output. Simple program, just Serial.begin(115200) and a delay(1000); in setup() then a simple Serial.println("Test"); in loop(). I've tried 3 known good cables, various boot and reset button sequences all with no joy. What is the secret ?

OK. Digikey, where I bought the part, sorted it out for me on a post I made after 9pm. Turns out programming is on one port and serial output is on the other unlike another part I've been using (Teyleten Robot ESP32-S3-DevKitC-1-N8R2) that has both on the same connection. Seems to me like someone at expressif could have taken the time to answer that for me, or put it in the docs somewhere. If it is in the docs I didn't see it.
