+# Echo-one 面对面翻译 · 双耳 BLE 协议（App 当前实现）
+
+日期：2026-10-10  
+对象：固件  
+对应 App：已按本文组包、解析。请对照固件实现逐条核对。  
+更早的讨论稿见 [face_to_face_ble_protocol.md](face_to_face_ble_protocol.md)（草案 v0.2）。**以本文为准**，不一致的地方按本文改固件或回我。
+
+---
+
+## 1. 形态
+
+两个人各戴一只耳机。TWS 拆开后，左耳、右耳各自一条 BLE 连到同一部手机。手机不收音、不放音，只做字幕和转发。
+
+| 谁在说 | 麦从哪来 | 云端 | 译文播到哪 |
+|---|---|---|---|
+| 戴左耳的人（源语言） | 左耳 `BB 90`，`EAR=1` | A 路 | 右耳 `AA 91`，`EAR=2` |
+| 戴右耳的人（目标语言） | 右耳 `BB 90`，`EAR=2` | B 路 | 左耳 `AA 91`，`EAR=1` |
+
+两条 BLE 互相独立，可以同时上行。经典蓝牙只用来进出这个模式（`AA 6B` / `AA 6C`），不传面对面的音频。
+
+旧的面对面 `AA 66` / `AA 67` 不动，和新模式互斥。通话翻译、AI、录音、OTA 也不并行。正在做这些事时，`AA 6B` 应回 `ERR_BUSY (0x02)`。
+
+---
+
+## 2. 两条 BLE 通道
+
+左右耳的 GATT **完全一样**。耳位不靠 UUID 区分，靠广播里的 `EAR`，以及音频帧低 4 位。
+
+| 特征 | UUID | 属性 | 方向 |
+|---|---|---|---|
+| Service | `AEAF5F32-0001-4C4B-A100-000000000001` | — | 扫描按这个 UUID 过滤 |
+| `CTRL_TX` | `AEAF5F32-0002-4C4B-A100-000000000001` | Write Without Response | App → 耳机，握手 / 配置 / 保活 / 退出 |
+| `CTRL_RX` | `AEAF5F32-0003-4C4B-A100-000000000001` | Notify | 耳机 → App，握手应答 / 事件 |
+| `AUDIO_UP` | `AEAF5F32-0004-4C4B-A100-000000000001` | Notify | 耳机 → App，本耳麦，`BB 90` |
+| `AUDIO_DOWN` | `AEAF5F32-0005-4C4B-A100-000000000001` | Write Without Response | App → 耳机，译文，`AA 91` |
+
+控制和音频必须分开。停流、打断如果排在音频写后面，点结束会没反应。
+
+链路要求（每条 LE 各自满足）：
+
+| 项 | 要求 |
+|---|---|
+| 写类型 | `CTRL_TX`、`AUDIO_DOWN` 都认 **Write Without Response** |
+| ATT MTU | App 请求 247。40ms 包大约 86 字节，MTU 至少要装得下一包 |
+| PHY | 优先 2M，不行再 1M |
+| 连接间隔 | 15~30ms。大于 40ms 译文会断 |
+| Slave latency | 0 |
+| Supervision timeout | 2~4s。App 被杀掉时来不及发退出，靠这条超时让固件自己恢复 |
+
+BLE 帧格式（和经典蓝牙同形，操作码空间独立）：
+
+```text
+AA/BB | OP | LEN | payload
+```
+
+`LEN` 是 payload 的字节数，不含这 3 字节头。
+
+---
+
+## 3. 启动时序
+
+耳机平时不要广播这个服务。只有收到经典链路上的 `AA 6B` 才拆 TWS、开始广播。
+
+```text
+App                         经典蓝牙              左耳 BLE            右耳 BLE

+ │  BB 90 右耳麦 / AA 91 译文给左耳，方向相反       │                  │
+```
+
+两只耳朵的握手互不等待。**两只都回了 `BB 83` 才开始推音频。** 12 秒内没握完，App 整场退出。
+
+---
+
+## 4. 经典蓝牙：进入 / 退出
+
+走现有经典链路（Android SPP，iOS GATT over BR/EDR）。不是 BLE。
+
+### 4.1 进入 `AA 6B`
+
+App 每次进入重新生成 4 字节随机 TOKEN。
+
+```text
+AA 6B 06 02 01 <TOKEN 4 字节>
+```
+
+| 字节 | 值 | 含义 |
+|---|---|---|
+| PROTO_VER | `0x02` | 本协议版本 |
+| CAP | `0x01` | 只要 G.722 |
+
+App 等 `BB EB` 的上限是 **3 秒**。超时就放弃，并补发 `AA 6C`。
+
+### 4.2 应答 `BB EB`
+
+整帧 10 字节：
+
+```text
+BB EB 07 <RESULT> <EAR_MASK> <PROTO_VER> <CODEC> <FRAME_MS> <FW_MINOR> <CLASSIC_KEEP>
+```
+
+| 字段 | App 怎么用 |
+|---|---|
+| RESULT | `0x00` 才继续扫 BLE。非 0 按第 8 节提示用户，并退出 |
+| EAR_MASK | bit0 = 左耳可用，bit1 = 右耳可用。**必须是 `0x03`**。缺一只不进入，请直接回 `0x03`，不要拆了一半 |
+| CODEC | `0x01` = G.722 |
+| FRAME_MS | `20` 或 `40`。决定一包里几帧。其它值 App 按 40 处理 |
+| FW_MINOR | 固件小版本，App 记下来，暂不分支 |
+| CLASSIC_KEEP | `0x01` = 拆 TWS 后经典链路还在；`0x00` = 经典链路会断 |
+
+`CLASSIC_KEEP=0` 时，App **不当成用户把耳机断开**。退出命令改走每只耳朵的 `AA 06`。下次经典蓝牙再连上，App 会先补发一次 `AA 6C`。
+
+### 4.3 退出 `AA 6C`
+
+```text
+AA 6C            →    BB EC 01 <RESULT>
+```
+
+`AA 6C` **没有长度字节**。
+
+必须幂等：当前不在面对面模式，也要回 `BB EC 01 00`，不要报错。App 在异常恢复时会无条件补发。
+
+`RESULT=0x00` 表示已重新组对，A2DP / HFP 恢复。
+
+---
+
+## 5. 广播与扫描
+
+收到 `AA 6B` 且 `RESULT=0`、双耳都可用之后，左右耳各自广播。
+
+厂商数据（AD Type `0xFF`）。Company ID 2 字节之后是下面 9 字节：
+
+```text
+F2 F2 | VER | EAR | TOKEN 4 字节 | BATT
+```
+
+| 字段 | 要求 |
+|---|---|
+| MAGIC | 固定 `F2 F2` |
+| VER | `0x02`，和 `AA 6B` 的 PROTO_VER 一致 |
+| EAR | `0x01` 左耳，`0x02` 右耳。两只耳机的名字可以相同 |
+| TOKEN | **原样回显这次 `AA 6B` 的 4 字节**。对不上 App 直接忽略 |
+| BATT | 低 7 位电量 0~100，最高位充电标志 |
+
+App 扫描规则：
+
+1. 只扫上面的 Service UUID。
+2. TOKEN 必须和这次 `AA 6B` 逐字节相同。旁边另一副同型号耳机不能连上。
+3. **必须同时看到 `EAR=1` 和 `EAR=2` 才连接。** 15 秒没集齐就发 `AA 6C` 回滚。
+4. iOS 拿不到 BLE MAC，身份只认 TOKEN + EAR。
+5. 扫描在 App 前台完成。建议建链期广播间隔 30~50ms。
+6. **30 秒内没被连上，该耳自己退出面对面**；两耳都退出后重新组对，并在经典链路上报 `BB EC 01 00`。
+
+连上之后该耳停止广播。
+
+---
+
+## 6. 每只耳朵的握手
+
+GATT 连上后 App 会：请求 MTU 247、连接优先级拉高、优先 2M PHY。  
+通知顺序：先 `CTRL_RX`，再 `AUDIO_UP`。两个通知都开了才发 HELLO。
+
+左右耳各走一遍，内容相同，TOKEN 相同。
+
+| 步骤 | App 发出 | 耳机应答 | 说明 |
+|---|---|---|---|
+| 1 | `AA 01 06 02 <TOKEN 4B> 01` | `BB 81 …` | HELLO。最后一字节 `01` 表示角色是 App。TOKEN 再对一次 |
+| 2 | `AA 02 03 00 50 00` | `BB 82 …` | 配置。见下表 |
+| 3 | `AA 03 00` | `BB 83 …` | 开流。应答成功后开始推 `BB 90` |
+| 4 | `AA 05 01 <SEQ>` | 可不回 | 两只都 `BB 83` 之后，每 5 秒一次。只做诊断，**不要因为没收到保活就断链** |
+
+`AA 02` 的 3 字节 payload：
+
+| 字节 | 当前固定值 | 含义 |
+|---|---|---|
+| VAD_MODE | `0x00` | 常发。静音也发，不要在耳机上切句 |
+| DOWN_GAIN | `0x50`（80） | 下行播放增益 0~100 |
+| TRIGGER | `0x00` | 免按键，连续拾音 |
+
+HELLO 应答 `BB 81`：App **只看 RESULT 是不是 0**。RESULT 非 0，这只耳朵判失败，整场退出。  
+`FRAME_MS` 以 `BB EB` 里那个字节为准，不从 `BB 81` 再改一回。
+
+`BB 82` / `BB 83` 的 RESULT 非 0，同样整场退出。
+
+开流之后如果要暂停而不断开，用 `AA 04 00`（STOP_STREAM）。当前正常结束不发这条，直接走第 7 节退出。
+
+---
+
+## 7. 退出
+
+顺序：
+
+1. 每只还连着的耳朵，`CTRL_TX` 发 `AA 06 00`。耳机停流、断开这条 BLE、准备重新组对。
+2. 经典链路还在，再发 `AA 6C`，等 `BB EC 01 00`。
+3. 经典链路已经断了（`CLASSIC_KEEP=0`）：这次只发 `AA 06`。App 记下标记，**下次经典蓝牙一连上就补发 `AA 6C`**。
+
+固件收到 `AA 06`、`AA 6C`，或者下面任一条件，都要自己恢复，不能停在面对面模式：
+
+| 条件 | 谁负责 |
+|---|---|
+| 广播 30 秒没人连 | 固件 |
+| LE 断连（supervision timeout 2~4s，含 App 被杀） | 固件。这是 App 被杀掉时的唯一恢复手段 |
+| App 主动结束 | App 发 `AA 06`，再视情况发 `AA 6C` |
+
+恢复要做完这些：停广播、断这条 GATT、两耳重新组对、A2DP / HFP 能用、按键和降噪回到进入前的状态。`CLASSIC_KEEP=0` 的固件，组对完成后要主动把经典链路连回手机。
+
+单耳 BLE 断开：App 结束整场，不再单耳继续翻。  
+来电：耳机在 `CTRL_RX` 上报第 9 节的退出事件，原因 `0x03`。App 结束会话并提示用户。固件恢复 HFP，把电话交给系统。
+
+---
+
+## 8. 音频
+
+编码固定 **G.722**。16 kHz、16 bit、单声道。20ms = 640 字节 PCM = 40 字节码流。
+
+`BB EB` 的 `FRAME_MS=40`：一包 2 帧，payload 80 字节。  
+`FRAME_MS=20`：一包 1 帧，payload 40 字节。
+
+### 8.1 上行 `AUDIO_UP`（耳机 → App）
+
+```text
+BB 90 <LEN> <EAR|FLAGS> <SEQ 小端 2 字节> <G.722…>
+```
+
+### 8.2 下行 `AUDIO_DOWN`（App → 耳机）
+
+```text
+AA 91 <LEN> <EAR|FLAGS> <SEQ 小端 2 字节> <G.722…>
+```
+
+`LEN` = 1（耳位和标志）+ 2（序号）+ G.722 字节数。  
+40ms 包：`LEN = 0x53`（83），整帧 86 字节。  
+20ms 包：`LEN = 0x2B`（43），整帧 46 字节。
+
+低 4 位是耳位，**必须等于这条链路自己的耳朵**。对不上就丢，并可回 `ERR_EAR_MISMATCH (0x08)`。  
+下行的耳位是「播给谁」：左耳麦的译文写到右耳那条链路，帧里 `EAR=2`。
+
+高 4 位：
+
+| 位 | 掩码 | 上行（耳机 → App） | 下行（App → 耳机） |
+|---|---|---|---|
+| bit4 | `0x10` | 本包含人声 | 一句译文开始 |
+| bit5 | `0x20` | 一段开始 | 播放结束 |
+| bit6 | `0x40` | 一段结束 | 打断：丢掉本耳还没播完的缓冲，从本包播 |
+| bit7 | `0x80` | 佩戴者本人在说话 | 不用 |
+
+`SEQ` 每耳独立，从 0 递增，到 `0xFFFF` 回绕。丢包不重传。
+
+`OWN_VOICE`（bit7）：没有骨传导 / VPU 时这一位请一直发 0。  
+App 只有在这只耳朵**曾经出现过 bit7=1** 之后，才丢掉 bit7=0 的包。一直是 0 的话，整路都会送去识别，不会被静音。
+
+下行节奏：没音频时 App 会先垫几包编码静音再送真声音，一句结束后再补一段静音。耳机用 `BB 88` 告诉 App 缓冲松紧（写在 `CTRL_RX`）：
+
+```text
+BB 88 <LEN> <ADJ>
+```
+
+| ADJ | 含义 |
+|---|---|
+| `+1` (`0x01`) | 缓冲少一包，马上再补一包 |
+| `-1` (`0xFF`) | 缓冲多一包，下一拍停发一包 |
+| `0` | 缓冲已经空，App 重新垫静音再起播 |
+
+这是补包 / 扣包，不是把速率改成 1.25 倍。
+
+---
+
+## 9. 事件
+
+写在 `CTRL_RX`：
+
+```text
+BB 87 <LEN> <EVENT> <PARAM…>
+```
+
+| EVENT | 含义 | PARAM | App 行为 |
+|---|---|---|---|
+| `0x01` | 按键 | `<EAR> <KEY> <ACTION>` | ACTION `0x01` 按下、`0x02` 抬起。当前是连续拾音，按键只更新界面上的左右标记 |
+| `0x02` | 佩戴 | `<EAR> <STATE>` | `0x00` 摘下，`0x01` 戴上，`0x02` 入盒。App 提示确认双耳都戴好 |
+| `0x03` | 电量 | `<EAR> <LEVEL>` | 低 7 位电量，最高位充电。App 暂不展示 |
+| `0x06` | 请求退出 | `<REASON>` | `0x03` 来电：App 结束面对面。`0x01` 用户操作，`0x02` 电量过低，`0x04` 对耳失联 |
+
+---
+
+## 10. 错误码
+
+`BB EB` 的 RESULT，以及握手应答里的 RESULT，用同一张表。
+
+| 值 | 名称 | App 提示 |
+|---|---|---|
+| `0x00` | OK | 继续 |
+| `0x01` | 固件不支持 / 版本过低 | 耳机固件需升级 |
+| `0x02` | 正在通话、AI、录音或 OTA | 请先结束当前功能 |
+| `0x03` | 有一只耳不可用 | 请确认双耳都已取出并佩戴 |
+| `0x04` | TOKEN 不一致 | 耳机未就绪 |
+| `0x05` | BLE 资源不足 | 耳机未就绪 |
+| `0x06` | 编码失败 | 耳机未就绪 |
+| `0x07` | 超时 | 耳机未就绪 |
+| `0x08` | 下行耳位和这条链路不符 | 记日志 |
+| `0x0A` | 固件内部错误 | 耳机未就绪 |
