协议 V1.10 (3be9e50) 三处新增落地:
1. dev_info_query 响应 data 补 loop_ver/loop_hw_ver (0x4A 缓存值, 未完成/失败为空串)
2. initialize 上报同样携带 (尽力, 可为空)
3. 新增 §4.25 loop_version_query: 0x4A 异步实时查询, 响应在 iot_verq_poll() 回包
固件:
- loop_uart_proto.h/c: 新增 LoopVerCache + g_lup_ver_cache (0x4A 缓存);
lup_cache_from_info() 写缓存, lup_refresh_version_cache() 后台刷新 (通道空闲才发)
- iot_mqtt_srv.c: dev_info_query/initialize 加字段; loop_version_query 分支
(暂存 msg_id/deadline 300ms, busy 拒绝重复查询); iot_verq_poll() 异步回包
(RESPONSE_READY -> code=0 + 三字段 + 同步刷缓存; TIMEOUT -> code=5 保缓存值);
后台刷新: 上电 iot_mqtt_init + OTA done (iot_ota_report_result ok=1) 置 dirty
关键设计: 版本来源=0x4A 实时查询 (非 OTA 元数据 version=目标版本);
缓存值语义 dev_info_query/initialize 同步回包不等异步; 与 TCP 共用 g_lup_cmd
单命令通道 (后发覆盖, 先发者超时 — 低频命令, 待板上验证时序)
单测: tests/test_iot_loop_ver.c — gcc 隔离 (extract+embed 6 函数 + mock)
44 断言全过: 版本帧解析(正常+4 错误路径) / 缓存写入+格式化(空串/NULL 防护) /
verq_poll 成功回包(code=0+三字段+topic+缓存刷新+通道释放) / 超时回包(code=5+缓存值) /
后台刷新(发起/忙不消费/响应消费/残留超时清理)
验证: check_c_balance.py 3 文件 OK; 待板上验证 UART2 0x4A 与 loop_data 共用总线时序

* test_iot_loop_ver.c — V1.10 验证: 0x4A 版本解析 + 版本缓存 + MQTT 异步回包时序
|
|
*
|
|
* 覆盖:
|
|
* 1. lup_parse_version: 0x4A 响应帧解析 (字段/错误路径)
|
|
* 2. lup_cache_from_info / iot_loop_ver_str / iot_loop_hw_ver_str: 缓存写入与格式化
|
|
* 3. iot_verq_poll 异步回包时序:
|
|
* - 命令 pending + RESPONSE_READY → code=0 回包 + 缓存刷新 + 通道释放
|
|
* - 命令 pending + TIMEOUT → code=5 回包
|
|
* - 后台刷新: dirty=1 + IDLE → 发起 0x4A (不设 pending)
|
|
* - 后台响应消费: !dirty + RESPONSE_READY → 更新缓存 + 释放
|
|
* - 残留超时清理: TIMEOUT → 归位 IDLE
|
|
*
|
|
* 编译: gcc -o test_iot_loop_ver test_iot_loop_ver.c && ./test_iot_loop_ver
