1、新增HTTPS故事播放功能：SendStoryRequest通过蓝牙MAC请求故事API，支持intro+body两段式无缝播放，替换原WebSocket故事请求方式； 2、新增HttpsPlaybackFromUrl通用HTTPS音频下载播放方法，支持JSON格式Opus帧流式解码播放； 3、新增RTC↔HTTPS双向音频切换三标志位状态机（opus_playback_active_/https_playback_active_/https_playback_abort_），HTTPS播放期间静默丢弃RTC PCM包，OnAudioOutput捕获is_opus_frame防止残留Opus帧杂音； 4、新增AbortHttpsPlayback中止方法，使用独立高优先级任务(priority=10)执行DMA flush；AbortSpeaking也新增DMA缓冲区flush确保扬声器立即静音； 5、协议层新增OnBotMessage回调，非字幕Bot下行消息立即中止HTTPS播放；volc_rtc_protocol移除is_binary依赖改为直接前缀检测，新增info前缀识别，subv字幕排除on_bot_message_由subtitle handler单独处理； 6、subtitle字幕USER/AI区分从CONFIG_VOLC_DEVICE_NAME比较改为bot_前缀判断，用户说话时立即中止HTTPS播放； 7、Kconfig新增STORY_API_URL故事播放API地址配置； 8、设备注册RTC服务时，设备名称从Wi-Fi MAC地址改为使用蓝牙MAC地址 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Firmware Section
Flashing Without Development Environment
For beginners, it's recommended to first use the firmware that can be flashed without setting up a development environment.
The firmware connects to the official xiaozhi.me server by default. Currently, personal users can register an account to use the Qwen real-time model for free.
👉 Flash Firmware Guide (No IDF Environment)
Development Environment
- Cursor or VSCode
- Install ESP-IDF plugin, select SDK version 5.3 or above
- Linux is preferred over Windows for faster compilation and fewer driver issues
- Use Google C++ code style, ensure compliance when submitting code
Developer Documentation
- Board Customization Guide - Learn how to create custom board adaptations for XiaoZhi
- IoT Control Module - Understand how to control IoT devices through AI voice commands
AI Agent Configuration
If you already have a XiaoZhi AI chatbot device, you can configure it through the xiaozhi.me console.
