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

<Steps>
  <Step title="Download Arduino IDE">
    <Card title="Download Arduino IDE" icon="download" href="https://www.arduino.cc/en/software">
      Get the Arduino IDE
    </Card>
  </Step>

  <Step title="Get the firmware">
    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.

    <Card title="View client.ino" icon="code" href="https://github.com/OpenInterpreter/01/blob/main/software/source/clients/esp32/src/client/client.ino">
      View the ESP32 firmware source code
    </Card>

  </Step>

  <Step title="Paste firmware into Arduino IDE">
    Open Arduino IDE and paste the client.ino contents.

    <img src="assets/pasted-client.png" alt="Pasted client.ino contents" width="60%" />
  </Step>

  <Step title="(Optional) Hardcode credentials">
    Hardcode your WiFi SSID, WiFi password, and server URL into the top of the `client.ino` file.

    <img src="assets/hardcode-wifi-pass-server.png" alt="Hardcode WiFi SSID and password" width="60%" />

    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. 
  </Step>

  <Step title="Install ESP32 boards">
    Go to Tools -> Board -> Boards Manager, search "esp32", then install the boards by Arduino and Espressif.

  </Step>

  <Step title="Install required libraries">
    Go to Tools -> Manage Libraries, then install the following:

    - M5Atom by M5Stack ([Reference](https://www.arduino.cc/reference/en/libraries/m5atom/))

    <img src="assets/M5-atom-library.png" alt="Install M5Atom library" width="60%" />

    <img src="assets/m5-atom-install-all.png" alt="Install all M5Atom dependencies" width="60%" />

    - WebSockets by Markus Sattler ([Reference](https://www.arduino.cc/reference/en/libraries/websockets/))

    <img src="assets/WebSockets by Markus Sattler.png" alt="Install WebSockets library" width="60%" />

    - AsyncTCP by dvarrel ([Reference](https://github.com/dvarrel/AsyncTCP))

    <img src="assets/AsyncTCP by dvarrel.png" alt="Install AsyncTCP library" width="60%" />

    - ESPAsyncWebServer by lacamera ([Reference](https://github.com/lacamera/ESPAsyncWebServer))

    <img src="assets/ESPAsyncWebServer by lacamera.png" alt="Install ESPAsyncWebServer library" width="60%" />

    <img src="assets/ESPAsyncWebServer-install-all.png" alt="Install all ESPAsyncWebServer dependencies" width="60%" />
  </Step>

  <Step title="Connect the board">
    To flash the .ino to the board, connect the board to the USB port.

    <img src="assets/connect_usb.jpeg" alt="Connect USB" width="60%" />
  </Step>

  <Step title="Select board and port">
    Select the port from the dropdown on the IDE, then select the M5Atom board (or M5Stack-ATOM if you have that).

    <img src="assets/Select Board and Port.png" alt="Select Board and Port" width="60%" />
  </Step>

  <Step title="Upload firmware">
    Click on upload to flash the board.

    <img src="assets/Upload.png" alt="Upload firmware" width="60%" />
  </Step>

  <Step title="Start the 01 server">
    Start the 01 server on your computer:
    ```
    poetry run 01 --server light
    ```
    This command starts the server and generates a URL.

    For remote connections, use:
    ```
    poetry run 01 --server light --expose
    ```
    This generates a public URL accessible from anywhere.
  </Step>

  <Step title="Connect ESP32 to the server">
    Connect your 01 device to the server using one of these methods:

    a) Hardcode credentials:
    - Modify the Wi-Fi and server credentials at the top of the `client.ino` file.
    - Flash the modified file to the ESP32.
    - This method is quick but less flexible for changing details later.

    b) Use the captive portal:
    - Power on your 01 device.
    - Connect to the '01-light' Wi-Fi network from your computer or smartphone.
    - A captive portal page should open automatically. If not, open a web browser.
    - Enter your Wi-Fi details and the server URL from step 1.
    - Click 'Connect' to save settings and connect your device.

    After successful connection, your ESP32 will be ready to communicate with the server.
