|

* @brief CBR1 断连温湿度扫描（规格书第 8 章）：500ms 重连广播 ↔ 500ms 扫描
|
||
* @author cyWu <1917507415@qq.com>
|
||
* @date 2026.09.07
|
||
* @version V1.1.6
|
||
* @history
|
||
* - V1.1.6, 2026.09.07, cyWu, 扫描上报只留 GAP 0xE2
|
||
* - V1.0.0, 2026.09.04, cyWu, P2 完整实现（P0/P1 为骨架）
|
||
*
|
||
* @note 门控（8 章表格）：已连接 / 未配对 / 配对中(usr_goto_pair) /
|
||
* OTA 中(usr_goto_updata) / 联动配置无效（缸体 0）→ 不扫描，纯广播。
|
||
* 进入交替后偶拍重连广播、奇拍扫描（8.2），一拍 = BOARD_ADV_SCAN_SLOT_MS。
|
||
*
|
||
* 匹配（8.1）：名字 == "JBao-"+DP8 缸体号（uint16 十进制，无前导零）
|
||
* 且厂商段 0xFFFF 首字节 == DP8 配置版本 → temp_x10=int8℃×10 喂联动；
|
||
* 湿度只打日志。名字/版本/解析任何一项不符 → 当没收到，不更新温度、
|
||
* 不关加热（保持上一态）。低开销：先滤名字，名字对了才找厂商段。
|
||
*
|
||
* ⚠ 上报回调跑在 BLE 栈线程；扫描只允许断连态，占用射频期间广播已
|
||
* 暂停（usr_le_set_adv_pause），不允许「边广播边扫」。
