Factory-Reset of an ESP32 Ethernet Brick

[yvo]

Dear list

I have two or three ESP32 Ethernet Brick's which I should reset to the original factory-settings.

The reason for it is, that the bricks are not able to get connected to the LAN anymore.

The documentation describes, that the USB-connection is only used as power source and to perform a factory reset on the Brick. And that in contrast to other Bricks, an ESP32 Brick connected to USB will not show up as Brick in a Brick Viewer connected to localhost.

But I wasn't able to find a description, how to run a Factory-Reset, either on tinkerforge.de or tinkerunity.org.

Question:

• Could someone guide me to the description of the Factory-Reset for an ESP32 Ethernet Brick?
• Or adding a short description here?

Looking forward to any hints.

Cheers,

Yvo

This sentence is worded somewhat misleadingly: ESP32 Bricks (and ESP32 Ethernet Bricks) don't show up as Bricks in the list of connected devices if connected via USB:

They still show up in the "Updates / Flashing" window under Bricks:

If you (re)flash the ESP32 Ethernet firmware here, this will also do a factory reset.
