I’ve got a standard uart setup with my esp32. RTS is connected to EN for resetting and DTR goes to the pin that specifies startup mode. When I do an upload task from the vscode ide it works fine. I can then open the serial monitor and start my code but in order to do that I have to manually inact…

[image] mchahn: Is there some way to specify that DTR and RTS should be turned off when the monitor starts so that my code can start? Do the documented monitor_rts and monitor_dtr options help you here?

Update: I set up espota (took 5 mins) and it works great but it didn’t do anything to help my serial monitor problem. If I get the serial output showing in my monitor task and then run the upload task, when it finishes uploading it switches back to the monitor task and the restarts the monitor. I…

Super helpful! I’m trying to program AI Thinker ESP32-CAM on platform IO and initially couldn’t get it to work. The program runs at first, but as soon as the serial monitor opens it stops running completely. And pressing the reset button doesn’t help. The serial monitor doesn’t work either. I was …
