Introduction

This example demonstrates the basic functionality of XiaoZhi voice interaction device on the Edgi-Talk platform, running RT-Thread RTOS. It allows users to quickly test Wi-Fi connection, key wake-up, and voice interaction, serving as a foundation for further application development.

Software Description

  • Developed on Edgi-Talk platform.

  • Example features:

    • Wi-Fi connection and status display

    • Key wake-up and voice interaction

    • Device state management (standby, listening, sleep)

Usage

WIFI Modification

  1. In main.c at line 36, locate the following code:

while (rt_wlan_connect("TEST", "88888888"));

  1. Replace “TEST” with your WiFi name and “88888888” with the password, then recompile and flash.

  2. For detailed WiFi usage, refer to: WIFI

Build and Download

  1. Open and compile the project.

  2. Connect the board USB to PC via DAP.

  3. Flash the compiled firmware to the device.

Running Result

  • After power-on, the device runs the example automatically.

  • The screen displays the current status:

    • Connecting – connecting to Wi-Fi

    • On standby – idle mode

    • Listening – ready for voice interaction

    • Sleeping – low-power sleep mode
