根因(非平台推测的环形缓冲/event_report队列):
mqtt_publish 的 mqttBuf=512B < loop_data(4通道)604B
→ MQTTSerialize_publish 返回 -2 不写 buf
→ len 为 uint32_t, -2 变 42.9亿
→ WCHNET 把清零缓冲+越界相邻全局(temp_guide=report_config→report_c)
当 520B 垃圾包发出 → broker 见非法类型0x00 RST → 重连风暴
修复(net_srv.c):
- MAX_MQTTBUF_LEN 512→1024 (容纳 604B loop_data)
- mqtt_publish: len uint32→int + 守卫 if(len<=0)return (序列化失败绝不发残缓冲)
- keepalive 9→60 (报告建议, 9s过激)
event_report 协议违规修复(iot_mqtt_srv.c):
- 重连重发保持原 msg_id/ts (V1.04 §5.3-2), 不再作废换号致平台去重失效
验证: tests/test_mqtt_publish_overflow.c 复现旧垃圾包+验证守卫/大缓冲;
tests/test_event_report.c T8 断言重连同 msg_id. 均全过.
遗留: ts=上电秒数非Unix时间戳, 待定方案(设备无RTC/SNTP)
