 1. **OTA_BEGIN**：手机发送 {total_size, image_crc32, version}。
    - image_crc32 = IEEE CRC32（poly 0xEDB88320，初值/异或出 0xFFFFFFFF，即 zlib crc32）
      对整个镜像 bin 文件的校验值。

    - 设备回 OTA_RSP(0x10, ok, 0) 后开始接收。
 2. **OTA_DATA**：从 offset=0 起严格顺序发送，每帧 {offset, data}。
-   - 设备侧用 **4KB 扇区缓冲** 攒数据，攒满一个 flash 扇区（4KB）后擦除并写入，
+   - 单帧 data 建议 ≤ 233B（MTU 247 时一次写入 244B = 帧开销 7 + offset 4 + data 233）；
-     然后回 OTA_RSP(0x11, ok, 已写 offset)——兼作流控与进度显示。
+     MTU 23 时单帧总长度不得超过 20B。
+   - 设备收到即写入 flash；每写满一个 4KB 扇区回一帧 OTA_RSP(0x11, ok, 已写 offset)
+     ——兼作流控与进度显示。
    - 手机端节奏：可按扇区等 ack 发送，也可连续发送；若收到 status=2 的应答，
      从应答中的 offset 处重发即可重新同步。
 3. **OTA_END**：{crc32}。设备 flush 尾部（0xFF 补齐到 4 字节对齐后写最后一个扇区），
    从 flash 回读整镜像复算 CRC32，与手机端比对：

+     （跳转不做校验，校验已在 OTA 过程完成）。

+## 23. BLE 三业务补齐：OTA + 设备信息查询 + CLI 透传（2026-09-03）
+
+mcm-ddc-04 目录已由用户删除，mcm-ddc-ble 成为唯一应用工程。本轮把 BLE 通道
+从"仅 CLI 透传"补齐为协议 V1.1 的三业务：CLI 透传（已有）、设备信息查询
+（新增）、双 bank 直写 OTA（从 04 git 历史 3135722 移植 app_ota.c/h）。
+
+### 23.1 协议升级 V1.1（docs/ble_protocol.md 重写）
+
+- 适配本工程实际：rdtss 服务（`...E0001` 下行写 / `...E0002` 上行 notify）、
+  广播名 `CAIIC-MCM-20260902`。
+- 新增信息查询帧：INFO_QUERY(0x20, {item_id}*n，空/0xFF=查全部) /
+  INFO_RSP(0x21, TLV {id,len,value}*n)。信息项：0x01 固件版本 u32、

+  0x04 电源电压 u16(mV)、0x05 运行时长 u32(s)、0x06 剩余堆 u32(B)。
+- OTA 帧 0x10~0x12/0x1F 从"保留"变为实现，流程与 04 一致（扇区级 ack 流控、
+  END 时整镜像 CRC32 校验 + 更新 bootsetting + 200ms 后复位）。
+
+### 23.2 OTA 移植（app_ota.c/h，368 行原样搬入）
+
+- 4KB 扇区 RAM 缓存攒满即擦写对侧 bank，无 flash 中转区；`Image$$ER_IROM1$$Base`
+  判定当前 bank（本工程链接 0x01008000 = APP1，OTA 写 APP2 0x01040000）。
+- `app_ble_proto_send_frame()` 由 static 改为导出供 OTA/INFO 应答；
+  OTA 状态码 BLE_OTA_ST_* 移入 app_ble_proto.h。
+- 断连即 `app_ota_abort()`（挂在 app_ble_proto_on_disconnect）。
+- uvprojx：USER 组加 app_ota.c / app_info.c / `..\..\Boot\src\boot_crc32.c`，
+  IncludePath 追加 `..\..\Boot\src`（dfu_layout.h / boot_crc32.h）。
+  与 app_ble_proto.c 一样只加 target "N32WB03x"。
+
+### 23.3 设备信息查询（新模块 app_info.c/h）
+
+- 温度：ADC CH7 内置温度传感器（`ADC_EnableTS` + 单发轮询 + 超时保护，
+  `ADC_ConverValueToTemperature` 用出厂 trim），参考 SDK 例程
+  `peripheral/ADC/ADC_Temperature`。
+- 电压：ADC CH6(VCC)，`ADC_ConverValueToVoltage`（600~3600mV 档 trim）。
+- ADC 懒初始化（AUDIOPLL 时钟源 + bypass filter + 过采样 3），首次查询时配好。
+- 风扇转速：`__weak app_fan_get_rpm()` 默认返回 0xFFFF（本板无测速电路），
+  产品代码重写该函数即可，协议不变。
+- CLI 新增 `devinfo` 命令打印同组数据（方便无手机时串口验证）。
+
+### 23.4 MTU 协商
+
+- `app_ble_connected()` 里设备主动 `ns_ble_mtu_set(247)`（ns_ble 库提供，
+  官方 DFU 的 OTA_CMD_MTU_UPDATE 同款调用）。MTU 247 时一次写入 244B，
+  OTA_DATA 单帧可带 233B 数据；MTU 协商失败则退化为 20B/写（协议按字节流
+  重组，两种情形都正确）。上行 notify 仍固定 20B 块，兼容任意对端。
+
+### 23.5 产物
+
+- 构建 0E/0W：`Code=34488 RO-data=3592 RW-data=2004 ZI-data=31012`
+  （含 4KB OTA 扇区缓存；用户 RAM 48KB 占用 33016B）。
+- APP bin = 39616B（≈38.7KB，bank 上限 224KB）。
+- 整包：`tools\out\caiic_ble_full.{hex,bin}`（Boot + 缺省 bootsetting + 本工程
+  APP1，bootsetting crc32=0x69A005D5）。
+- 待上板验证：BLE 连接后 MTU 交换、INFO_QUERY 应答、OTA 全流程（写 APP2 →
+  复位 → Boot 跳 APP2）。
+
+## 24. OTA 去 4KB 扇区缓存，改直写（2026-09-03）
+
+- 背景：23 节版本整包烧录后不运行。静态校验发现该包 APP1 向量表初始 SP 仍停在
+  旧版栈顶 0x2000B0D0，而新增 4KB OTA 缓存已把 ZI 顶到 0x2000B8F8——栈顶落在
+  ZI/堆区域内，启动即崩（增量构建产物不一致所致；教训：出包一律 `UV4 -r`
+  全量重建，并核对向量表 SP 与 map 的 `__initial_sp` 一致）。
+- 应用户要求去掉 4KB 扇区 RAM 缓存设计，app_ota.c 重写为**直写**：
+  - 惰性擦除：数据首次落入某扇区时先擦该扇区（`ota_erase_up_to`）；
+  - 收到 OTA_DATA 立即 `Qflash_Write` 写入（bulk 对齐部分直接用帧 payload，
+    不再经过大缓冲）；
+  - 仅保留 4 字节对齐暂存（Qflash 写要求 4B 对齐，尾部 OTA_END 时 0xFF 补齐）；
+  - 流控/进度不变：每写满一个 4KB 扇区回一帧 OTA_RSP(ok, offset)。
+- 效果：ZI 从 31012 降回 26912（-4KB），本版 `Code=34564 RO=3592 RW=2016
+  ZI=26912`，APP bin 39692B，栈顶 0x2000B100 与 map `__initial_sp` 一致。
+- 整包：`tools\out\caiic_ble_full.{hex,bin}`（bootsetting crc32=0xF15790D8）。
+- 协议文档 §6 已同步直写描述（对外流程与帧格式不变）。
+- 上板验证：整包烧录后正常启动，串口 banner + `caiic->` 正常（2026-09-03 确认）。
