#70954 Hi, I'm new to the ESP8266 and how it works as an Shield plugged into an Arduino module.
I'm learning to use the kit that is part of the robot car kit from Osoyoo.

That uses an ESP-13 board (the type with the 2-pole DIP switch) plugged into an Arduino board.
It works OK. I can program them using the Arduino IDE.

I have a basic newbie question;-
How does system program both the ESP-13 microcontroller and also the Arduino uP with 1 upload via USB?

Does the data on the USB lines go to both controllers at the sane time?
or
does the USB data only go the the Arduino uP, and that device program the ESP-13 later ?

Its a basic question, but I and other newbies would value your helpful answers.

Thanks
