Quick Start

Use this page to get your LAFVIN AIoT Starter Kit online, bound to the Xiaozhi backend, and ready for its first voice conversation.

What You Will Finish

In about 15 to 20 minutes, you will:

  • flash the firmware

  • connect the board to your 2.4 GHz Wi-Fi network

  • bind the board to your Xiaozhi account

  • start your first voice conversation

Before You Begin

Make sure you have:

  • an ESP32-S3 board installed on the AI Chatbot IoT Shield

  • a USB Type-C data cable

  • Chrome or Edge for online flashing

  • access to a 2.4 GHz Wi-Fi network

  • a phone that can connect to the temporary Xiaozhi hotspot

  • a Xiaozhi account, or a phone number that can receive the verification code

Warning

Use a USB Type-C data cable. Charging-only cables can power the board but cannot be used for flashing.

Note

ESP32-S3 supports 2.4 GHz Wi-Fi only. If your router exposes separate 2.4 GHz and 5 GHz networks, choose the 2.4 GHz network during setup.

Quick Setup

Step 1: Install the Driver

If your board does not appear as a serial device, install the CP210x USB-to-UART driver for your operating system:

Step 2: Flash the Firmware Online

Use the online flasher as the default setup path. It does not require a local flashing tool or a separate firmware package.

Note

If the online flasher cannot detect your board, install the driver first and then use the local flashing alternative in 4.Xiaozhi AI Setup.

Step 3: Connect the Board to Wi-Fi

  1. After flashing, restart the board. It should enter Wi-Fi provisioning mode automatically.

  2. On your phone, connect to the hotspot named Xiaozhi-XXXX.

  3. If the configuration page does not open automatically, enter http://192.168.4.1 in your browser.

  4. Select your 2.4 GHz Wi-Fi network, enter the password, and tap Save.

  5. Wait for the board to restart and announce a 6-digit verification code.

Note

Keep the board powered on after Wi-Fi setup. You will need the 6-digit verification code in the next step.

Step 4: Bind the Board in the Xiaozhi Backend

  1. Open Xiaozhi and sign in or create an account.

  2. Open the console and create an agent.

  3. Click Add Device.

  4. Enter the 6-digit verification code announced by the board.

  5. Confirm the binding and wait for the board to restart.

Post-Setup Functional Check

After firmware flashing, Wi-Fi setup, and backend binding are complete, use the checks below to confirm that the full system is working:

You can refer to 2.Hardware Connection for the wiring diagrams and pin assignment table for each sensor and actuator. After the hardware connections are complete, use the voice checks below to confirm that the system is working correctly.

  1. Voice Test: Say Hi, ESP and confirm that the assistant wakes up and responds.

  2. LED Test: Say Hi, ESP, turn on LED to confirm that the RGB LED responds.

  3. Sensor Test: Say Hi, ESP, check temperature to confirm that the sensor data path is working.

Tip

If a hardware module does not respond, return to 2.Hardware Connection and recheck the wiring before reflashing the firmware.

Optional: Customize the Agent Role

Open Configure Role if you want to change the assistant name, voice, language, or personality:

  • Assistant Name: Name your AI assistant

  • Voice Role: Select your preferred voice style

  • Language Preference: Set the conversation language

  • Role Introduction: Define the assistant personality

  • Language Model: Select the model used by the backend

Sample prompt:
I am a virtual assistant called {{assistant_name}}. I communicate exclusively in English with a natural, friendly voice. I provide helpful, accurate information and assist users with their queries while maintaining a conversational tone. I adapt my speaking style to match the user's needs and always aim to deliver clear, concise responses in fluent English.
