ESP32 Forum

hello friends..
I have following observation..
after Make flash monitor
I unplug the esp32 from my Host computer..then when again powered ON..things wont work.
I need to press Reset Button 'EN' on esp32 to get it working...
Whats going on ?

Some boards don't use the proper technique for the EN and GPIO pins. So when the board powers up without the com port initialized it puts the ESP32 it in the wrong state on power up.

Grab a program called Tera Term. Have used this for over 10 years now. It's an excellent com port serial monitor.

When you plug your device in to your PC, open Tera Term and connect to its com port and you will see that this issue goes away on those troublesome boards.
