FF 52 00 20 06 26 payload = 00 20 06 chk = 00^20^06 = 26 ✅ 这就是典型的 3-byte bitmask（24 个勾选位够用），你“bit 对应 UI 哪个勾”暂时先别钉死，等你再抓几组“勾选变化”的对照包就能反推出来。 帧：FF FF 4B 28 23 64 C6 25 00 8C 映射： Ko_raw = 0x2328 = 9000 → Ko = 9000/10 = 900 KoCount = 0x64 → 100 KPO_raw = 0x25C6 = 9670 KPOCount = 0x00 → 0 chk XOR ✅ 帧：FF FF 56 2E 05 19 00 64 2E 28 23 00 40 00 00 00 00 33 19 00 -> 25°C（当作“温度”） 因为你后面自己也用新截图验证了：UI 的 Temp 变了，但这两个字节不变。 所以它几乎可以排除是“实时温度”。 这帧看起来像“DR 标定快照 + 一些运行状态”，其中： 2E 05 作为 u16le = 0x052E = 1326 → Vcc = 1326/400 = 3.315V ✅ 2E 单字节 → Vr_raw，Vr = 2E/20 = 2.30 ✅ 28 23 → Ko_raw（再次出现）✅ 00（在 Ko 后面那个单字节）非常像 Vrev（UI 里 Vrev=0）✅ 40 很像一个 flag byte（或其中一个 flag byte）✅ 后面一串 00 基本就是保留/对齐/扩展 GPS State（3 字节 flags，高置信是“bitmask”） 完整帧：FF FF 52 00 20 06 26 idx hex 含义 0 FF 帧头 1 FF 帧头 2 52 块类型：GPS State 3 00 GPS 状态

字节=24 个 bit 完全够装。 DrCalibration（Ko / KPO / Count，高置信） 你日志把它拆行了，但应当拼成一帧： 完整帧：FF FF 4B 28 23 64 C6 25 00 8C payload（6 字节）：28 23 64 C6 25 00 idx hex 含义（小端） 0 FF 帧头 1 FF 帧头 2 4B 块类型：DrCalibration 3 28

是非常典型的“出厂/室温标定参考点”（很多设备会用一个固定参考温度做补偿/校准参数） 6 00 7 64 很像 Count=100（与 0x4B 的 KoCount 一致） 8 2E idx8 很可能是 Vr_raw，Vr = idx8 / 20 = 2.30 9 28 Ko_raw 低字节 10 23 Ko_raw 高字节 → 0x2328=9000（与 0x4B 完全一致） idx9-10：Ko_raw（/10） 11 00 保留/小字段 12 40 flags 或配置字节（bitmask 的可能性很高） 0x40 = 0100 0000b，看起来就是“只开了某一个 bit”。把多个 checkbox 压进一个字节/整数里（每个 bit 表示一个布尔状态）叫 bitmask/flag register，这是协议/寄存器里非常常见的省空间做法 13 00 保留 14 00 保留 15 00 保留 16 33 校验：XOR(payload)=33 ✅ idx3-4 作为一个 u16le：0x052E=1326 /400 这种比例是很常见的一类“定点电压单位”：把电压用整数表示，每 1 count = 1/400 V = 0.0025 V = 2.5 mV。所以你这帧里如果 idx3-4 取 u16le = 0x052E = 1326，那么 Vcc = 1326 / 400 = 3.315 V idx5 的 0x19=25 可能是温度（25°C），也可能是某种状态码。你截图里温度=12，但那是 10:08:48 时刻；0x56 这帧是 10:07:46，上电瞬间温度/显示刷新不同步很常见。 后续的二进制帧中会每秒更新温度 OBU 基本信息/状态（ID/FW 高置信，其余部分待验证） 完整帧： FF FF 53 E3 20 00 00 C3 01 27 40
