To set up the ESP32 for use with 01, follow this guide to install the firmware:

1. Download [Arduino IDE](https://www.arduino.cc/en/software).

2. Get the firmware by copying the contents of [client.ino](https://github.com/OpenInterpreter/01/blob/main/software/source/clients/esp32/src/client/client.ino) from the 01 repository.

</div>

3. Open Arduino IDE and paste the client.ino contents.

4. Hardcode your WiFi SSID, WiFi password, and server URL into the code.

</div>

  <div style="width: 80%;">
    Hardcoding is recommended for a more streamlined setup and development environment. However, if you don't hardcode these values or if the ESP32 can't connect using the provided information, it will automatically default to a captive portal for configuration.

5. Go to Tools -> Board -> Boards Manager, search "esp32", then install the boards by Arduino and Espressif.
