火山 RTC SDK 在 ICE Agent 失败路径下 (如服务端 session idle timeout / NAT 表过期)
会用 message=NULL 调用 _on_global_error 回调, 触发 printf("%s", NULL) → strlen(NULL)
→ LoadProhibited panic → 设备无故重启。
实测复现条件:
- 设备进入 idle 后 10+ 分钟 (无用户活动)
- RTC 服务端清理 stale signaling 连接 + NAT 表项过期
- ICE Agent 收到 keepalive failure → state=FAILED
- ConnectionService.c 触发 _on_global_error(code, message=NULL)
- panic at strlen ROM 0x400556d5
注意: 这是低频偶发, 不是每次 idle 必触发。同样 idle 20 分钟有时不触发 (取决于
SDK 内部 ICE state machine 错误路径走向)。修复成本极低 (一行判空), 收益是消除
该偶发崩溃风险。
修改:
components/common/src/volc_rtc.c:430
LOGI("global error %d %s\n", code, message);
→
LOGI("global error %d %s\n", code, message ? message : "(null)");
修复后行为:
- 服务端 idle 超时仍会触发 _on_global_error
- 日志正常打印 "global error <code> (null)" 不再 panic
- 设备继续保持 idle, 下次按 BOOT 时 SDK 自动重新 join_room
- 软退出+保留 engine 的快速唤醒优化继续生效 (License 节省策略不变)

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.
