Serial Console

Prerequisites

• esptool
• USB to Serial adapter (must have RTS and DTR pins)
• Female-to-female dupont connecting wires

Configuration

1. Remove the rear cover of the oven.
2. Remove the plastic cover protecting the PCB.

3. Connect the USB-to-serial adapter to the debug pins. In order to use the automatic bootloader, all 5 pins must be connected as follows:

Connecting To The Oven

The following instructions apply to MacOS only, though Linux should be fairly similar.

1. Plug the USB-to-serial adapter into your computer before plugging in the oven (at least in my case it only worked this way).

2. Find the path to your adapter:

ls /dev/cu.*

3. Open a screen session:

screen <path_to_adapter> 230400

4. Plug in the oven.
