How do I find out if it sends signon message?
If you meen the RXD and TXD LEDs on the programer then just one is blinking.

I was trying to upload code to my prototype board but I was stuck on "connecting..." The ESP32 is well soldered and was not heating too much when being soldered. The thing that is probably the problem but I don't know how to fix it is ArduinoIDE setting. I am using ESP32-WROVER-IB(16MB) and programe...
