Hello Philippe,

What do you mean by factory reset? Do you want flash the AT firmware?

Every time you flash a new Arduino sketch, it automatically flashes a new firmware to your ESP32.

Hello Philippe,

I see. Those configs are stored in the flash memory. So, I recommend using the esptool: https://github.com/espressif/esptool

Basically, you need to send a similar command to erase the flash memory:

esptool.py --chip esp8266 p com7 erase_flash

You need to replace with your ESP8266 port.

I hope that helps,
Rui

Exactly (write esp32 for the ESP32 chip). You will need either Python 2.7 or Python 3.4 or newer installed on your system.

The latest stable esptool.py release can be installed from pypi via pip or you can download the repository on GitHub:

$ pip install esptool

Then, run:

esptool.py --chip esp32 p com7 erase_flash

With your ESP32 com port. It should work
