My checklist for establishing connection with an ESP8266 devkit is the one below :

Branch USB cable between computer and devkit
Start ESPlorer
Set 115200 bauds and click "Connect"
Switch on then off RTS button

I wonder about this very last step. If I don't switch on then off the RTS button, nothing happens.
What is the reason about that?

Thanks for your replies,
