+# MCP (Model Context Protocol) 交互流程
+
+NOTICE: AI 辅助生成, 在实现后台服务时, 请参照代码确认细节!!
+
+本项目中的 MCP 协议用于后台 API（MCP 客户端）与 ESP32 设备（MCP 服务器）之间的通信，以便后台能够发现和调用设备提供的功能（工具）。
+
+## 协议格式
+
+根据代码 (`main/protocols/protocol.cc`, `main/mcp_server.cc`)，MCP 消息是封装在基础通信协议（如 WebSocket 或 MQTT）的消息体中的。其内部结构遵循 [JSON-RPC 2.0](https://www.jsonrpc.org/specification) 规范。
+
+整体消息结构示例：
+
+```json
+{
+  "session_id": "...", // 会话 ID
+  "type": "mcp",       // 消息类型，固定为 "mcp"
+  "payload": {         // JSON-RPC 2.0 负载
+    "jsonrpc": "2.0",
+    "method": "...",   // 方法名 (如 "initialize", "tools/list", "tools/call")
+    "params": { ... }, // 方法参数 (对于 request)
+    "id": ...,         // 请求 ID (对于 request 和 response)
+    "result": { ... }, // 方法执行结果 (对于 success response)
+    "error": { ... }   // 错误信息 (对于 error response)
+  }
+}
+```
+
+其中，`payload` 部分是标准的 JSON-RPC 2.0 消息：
+
+- `jsonrpc`: 固定的字符串 "2.0"。
+- `method`: 要调用的方法名称 (对于 Request)。
+- `params`: 方法的参数，一个结构化值，通常为对象 (对于 Request)。
+- `id`: 请求的标识符，客户端发送请求时提供，服务器响应时原样返回。用于匹配请求和响应。
+- `result`: 方法成功执行时的结果 (对于 Success Response)。
+- `error`: 方法执行失败时的错误信息 (对于 Error Response)。
+
+## 交互流程及发送时机
+
+MCP 的交互主要围绕客户端（后台 API）发现和调用设备上的“工具”（Tool）进行。
+
+1.  **连接建立与能力通告**
+
+    - **时机：** 设备启动并成功连接到后台 API 后。
+    - **发送方：** 设备。
+    - **消息：** 设备发送基础协议的 "hello" 消息给后台 API，消息中包含设备支持的能力列表，例如通过支持 MCP 协议 (`"mcp": true`)。
+    - **示例 (非 MCP 负载，而是基础协议消息):**
+      ```json
+      {
+        "type": "hello",
+        "version": ...,
+        "features": {
+          "mcp": true,
+          ...
+        },
+        "transport": "websocket", // 或 "mqtt"
+        "audio_params": { ... },
+        "session_id": "..." // 设备收到服务器hello后可能设置
+      }
+      ```
+
+2.  **初始化 MCP 会话**
+
+    - **时机：** 后台 API 收到设备 "hello" 消息，确认设备支持 MCP 后，通常作为 MCP 会话的第一个请求发送。
+    - **发送方：** 后台 API (客户端)。
+    - **方法：** `initialize`
+    - **消息 (MCP payload):**
+
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "method": "initialize",
+        "params": {
+          "capabilities": {
+            // 客户端能力，可选
+
+            // 摄像头视觉相关
+            "vision": {
+              "url": "...", //摄像头: 图片处理地址(必须是http地址, 不是websocket地址)
+              "token": "..." // url token
+            }
+
+            // ... 其他客户端能力
+          }
+        },
+        "id": 1 // 请求 ID
+      }
+      ```
+
+    - **设备响应时机：** 设备收到 `initialize` 请求并处理后。
+    - **设备响应消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "id": 1, // 匹配请求 ID
+        "result": {
+          "protocolVersion": "2024-11-05",
+          "capabilities": {
+            "tools": {} // 这里的 tools 似乎不列出详细信息，需要 tools/list
+          },
+          "serverInfo": {
+            "name": "...", // 设备名称 (BOARD_NAME)
+            "version": "..." // 设备固件版本
+          }
+        }
+      }
+      ```
+
+3.  **发现设备工具列表**
+
+    - **时机：** 后台 API 需要获取设备当前支持的具体功能（工具）列表及其调用方式时。
+    - **发送方：** 后台 API (客户端)。
+    - **方法：** `tools/list`
+    - **消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "method": "tools/list",
+        "params": {
+          "cursor": "" // 用于分页，首次请求为空字符串
+        },
+        "id": 2 // 请求 ID
+      }
+      ```
+    - **设备响应时机：** 设备收到 `tools/list` 请求并生成工具列表后。
+    - **设备响应消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "id": 2, // 匹配请求 ID
+        "result": {
+          "tools": [ // 工具对象列表
+            {
+              "name": "self.get_device_status",
+              "description": "...",
+              "inputSchema": { ... } // 参数 schema
+            },
+            {
+              "name": "self.audio_speaker.set_volume",
+              "description": "...",
+              "inputSchema": { ... } // 参数 schema
+            }
+            // ... 更多工具
+          ],
+          "nextCursor": "..." // 如果列表很大需要分页，这里会包含下一个请求的 cursor 值
+        }
+      }
+      ```
+    - **分页处理：** 如果 `nextCursor` 字段非空，客户端需要再次发送 `tools/list` 请求，并在 `params` 中带上这个 `cursor` 值以获取下一页工具。
+
+4.  **调用设备工具**
+
+    - **时机：** 后台 API 需要执行设备上的某个具体功能时。
+    - **发送方：** 后台 API (客户端)。
+    - **方法：** `tools/call`
+    - **消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "method": "tools/call",
+        "params": {
+          "name": "self.audio_speaker.set_volume", // 要调用的工具名称
+          "arguments": {
+            // 工具参数，对象格式
+            "volume": 50 // 参数名及其值
+          }
+        },
+        "id": 3 // 请求 ID
+      }
+      ```
+    - **设备响应时机：** 设备收到 `tools/call` 请求，执行相应的工具函数后。
+    - **设备成功响应消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "id": 3, // 匹配请求 ID
+        "result": {
+          "content": [
+            // 工具执行结果内容
+            { "type": "text", "text": "true" } // 示例：set_volume 返回 bool
+          ],
+          "isError": false // 表示成功
+        }
+      }
+      ```
+    - **设备失败响应消息 (MCP payload):**
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "id": 3, // 匹配请求 ID
+        "error": {
+          "code": -32601, // JSON-RPC 错误码，例如 Method not found (-32601)
+          "message": "Unknown tool: self.non_existent_tool" // 错误描述
+        }
+      }
+      ```
+
+5.  **设备主动发送消息 (Notifications)**
+    - **时机：** 设备内部发生需要通知后台 API 的事件时（例如，状态变化，虽然代码示例中没有明确的工具发送此类消息，但 `Application::SendMcpMessage` 的存在暗示了设备可能主动发送 MCP 消息）。
+    - **发送方：** 设备 (服务器)。
+    - **方法：** 可能是以 `notifications/` 开头的方法名，或者其他自定义方法。
+    - **消息 (MCP payload):** 遵循 JSON-RPC Notification 格式，没有 `id` 字段。
+      ```json
+      {
+        "jsonrpc": "2.0",
+        "method": "notifications/state_changed", // 示例方法名
+        "params": {
+          "newState": "idle",
+          "oldState": "connecting"
+        }
+        // 没有 id 字段
+      }
+      ```
+    - **后台 API 处理：** 接收到 Notification 后，后台 API 进行相应的处理，但不回复。

+# MCP 协议物联网控制用法说明
+
+> 本文档介绍如何基于 MCP 协议实现 ESP32 设备的物联网控制。详细协议流程请参考 [`mcp-protocol.md`](./mcp-protocol.md)。
+
+## 简介
+
+MCP（Model Context Protocol）是新一代推荐用于物联网控制的协议，通过标准 JSON-RPC 2.0 格式在后台与设备间发现和调用"工具"（Tool），实现灵活的设备控制。
+
+## 典型使用流程
+
+1. 设备启动后通过基础协议（如 WebSocket/MQTT）与后台建立连接。
+2. 后台通过 MCP 协议的 `initialize` 方法初始化会话。
+3. 后台通过 `tools/list` 获取设备支持的所有工具（功能）及参数说明。
+4. 后台通过 `tools/call` 调用具体工具，实现对设备的控制。
+
+详细协议格式与交互请见 [`mcp-protocol.md`](./mcp-protocol.md)。
+
+## 设备端工具注册方法说明
+
+设备通过 `McpServer::AddTool` 方法注册可被后台调用的"工具"。其常用函数签名如下：
+
+```cpp
+void AddTool(
+    const std::string& name,           // 工具名称，建议唯一且有层次感，如 self.dog.forward
+    const std::string& description,    // 工具描述，简明说明功能，便于大模型理解
+    const PropertyList& properties,    // 输入参数列表（可为空），支持类型：布尔、整数、字符串
+    std::function<ReturnValue(const PropertyList&)> callback // 工具被调用时的回调实现
+);
+```
+- name：工具唯一标识，建议用"模块.功能"命名风格。
+- description：自然语言描述，便于 AI/用户理解。
+- properties：参数列表，支持类型有布尔、整数、字符串，可指定范围和默认值。
+- callback：收到调用请求时的实际执行逻辑，返回值可为 bool/int/string。
+
+## 典型注册示例（以 ESP-Hi 为例）
+
+```cpp
+void InitializeTools() {
+    auto& mcp_server = McpServer::GetInstance();
+    // 例1：无参数，控制机器人前进
+    mcp_server.AddTool("self.dog.forward", "机器人向前移动", PropertyList(), [this](const PropertyList&) -> ReturnValue {
+        servo_dog_ctrl_send(DOG_STATE_FORWARD, NULL);
+        return true;
+    });
+    // 例2：带参数，设置灯光 RGB 颜色
+    mcp_server.AddTool("self.light.set_rgb", "设置RGB颜色", PropertyList({
+        Property("r", kPropertyTypeInteger, 0, 255),
+        Property("g", kPropertyTypeInteger, 0, 255),
+        Property("b", kPropertyTypeInteger, 0, 255)
+    }), [this](const PropertyList& properties) -> ReturnValue {
+        int r = properties["r"].value<int>();
+        int g = properties["g"].value<int>();
+        int b = properties["b"].value<int>();
+        led_on_ = true;
+        SetLedColor(r, g, b);
+        return true;
+    });
+}
+```
+
+## 常见工具调用 JSON-RPC 示例
+
+### 1. 获取工具列表
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "tools/list",
+  "params": { "cursor": "" },
+  "id": 1
+}
+```
+
+### 2. 控制底盘前进
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "tools/call",
+  "params": {
+    "name": "self.chassis.go_forward",
+    "arguments": {}
+  },
+  "id": 2
+}
+```
+
+### 3. 切换灯光模式
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "tools/call",
+  "params": {
+    "name": "self.chassis.switch_light_mode",
+    "arguments": { "light_mode": 3 }
+  },
+  "id": 3
+}
+```
+
+### 4. 摄像头翻转
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "tools/call",
+  "params": {
+    "name": "self.camera.set_camera_flipped",
+    "arguments": {}
+  },
+  "id": 4
+}
+```
+
+## 备注
+- 工具名称、参数及返回值请以设备端 `AddTool` 注册为准。
+- 推荐所有新项目统一采用 MCP 协议进行物联网控制。

+
+MQTT + UDP 混合协议通过以下设计实现高效的音视频通信：
+
+- **分离式架构**：控制与数据通道分离，各司其职
+- **加密保护**：AES-CTR 确保音频数据安全传输
+- **序列化管理**：防止重放攻击和数据乱序
+- **自动恢复**：支持连接断开后的自动重连
+- **性能优化**：UDP 传输保证音频数据的实时性
+
+该协议适用于对实时性要求较高的语音交互场景，但需要在网络复杂度和传输性能之间做出权衡。

+以下是一份基于代码实现整理的 WebSocket 通信协议文档，概述设备端与服务器之间如何通过 WebSocket 进行交互。
+
+该文档仅基于所提供的代码推断，实际部署时可能需要结合服务器端实现进行进一步确认或补充。
+
+---
+
+## 1. 总体流程概览
+
+1. **设备端初始化**  
+   - 设备上电、初始化 `Application`：  
+     - 初始化音频编解码器、显示屏、LED 等  
+     - 连接网络  
+     - 创建并初始化实现 `Protocol` 接口的 WebSocket 协议实例（`WebsocketProtocol`）  
+   - 进入主循环等待事件（音频输入、音频输出、调度任务等）。
+
+2. **建立 WebSocket 连接**  
+   - 当设备需要开始语音会话时（例如用户唤醒、手动按键触发等），调用 `OpenAudioChannel()`：  
+     - 根据配置获取 WebSocket URL
+     - 设置若干请求头（`Authorization`, `Protocol-Version`, `Device-Id`, `Client-Id`）  
+     - 调用 `Connect()` 与服务器建立 WebSocket 连接  
+
+3. **设备端发送 "hello" 消息**  
+   - 连接成功后，设备会发送一条 JSON 消息，示例结构如下：  
+   ```json
+   {
+     "type": "hello",
+     "version": 1,
+     "features": {
+       "mcp": true
+     },
+     "transport": "websocket",
+     "audio_params": {
+       "format": "opus",
+       "sample_rate": 16000,
+       "channels": 1,
+       "frame_duration": 60
+     }
+   }
+   ```
+   - 其中 `features` 字段为可选，内容根据设备编译配置自动生成。例如：`"mcp": true` 表示支持 MCP 协议。
+   - `frame_duration` 的值对应 `OPUS_FRAME_DURATION_MS`（例如 60ms）。
+
+4. **服务器回复 "hello"**  
+   - 设备等待服务器返回一条包含 `"type": "hello"` 的 JSON 消息，并检查 `"transport": "websocket"` 是否匹配。  
+   - 服务器可选下发 `session_id` 字段，设备端收到后会自动记录。  
+   - 示例：
+   ```json
+   {
+     "type": "hello",
+     "transport": "websocket",
+     "session_id": "xxx",
+     "audio_params": {
+       "format": "opus",
+       "sample_rate": 24000,
+       "channels": 1,
+       "frame_duration": 60
+     }
+   }
+   ```
+   - 如果匹配，则认为服务器已就绪，标记音频通道打开成功。  
+   - 如果在超时时间（默认 10 秒）内未收到正确回复，认为连接失败并触发网络错误回调。
+
+5. **后续消息交互**  
+   - 设备端和服务器端之间可发送两种主要类型的数据：  
+     1. **二进制音频数据**（Opus 编码）  
+     2. **文本 JSON 消息**（用于传输聊天状态、TTS/STT 事件、MCP 协议消息等）  
+
+   - 在代码里，接收回调主要分为：  
+     - `OnData(...)`:  
+       - 当 `binary` 为 `true` 时，认为是音频帧；设备会将其当作 Opus 数据进行解码。  
+       - 当 `binary` 为 `false` 时，认为是 JSON 文本，需要在设备端用 cJSON 进行解析并做相应业务逻辑处理（如聊天、TTS、MCP 协议消息等）。  
+
+   - 当服务器或网络出现断连，回调 `OnDisconnected()` 被触发：  
+     - 设备会调用 `on_audio_channel_closed_()`，并最终回到空闲状态。
+
+6. **关闭 WebSocket 连接**  
+   - 设备在需要结束语音会话时，会调用 `CloseAudioChannel()` 主动断开连接，并回到空闲状态。  
+   - 或者如果服务器端主动断开，也会引发同样的回调流程。
+
+---
+
+## 2. 通用请求头
+
+在建立 WebSocket 连接时，代码示例中设置了以下请求头：
+
+- `Authorization`: 用于存放访问令牌，形如 `"Bearer <token>"`  
+- `Protocol-Version`: 协议版本号，与 hello 消息体内的 `version` 字段保持一致  
+- `Device-Id`: 设备物理网卡 MAC 地址
+- `Client-Id`: 软件生成的 UUID（擦除 NVS 或重新烧录完整固件会重置）
+
+这些头会随着 WebSocket 握手一起发送到服务器，服务器可根据需求进行校验、认证等。
+
+---
+
+## 3. 二进制协议版本
+
+设备支持多种二进制协议版本，通过配置中的 `version` 字段指定：
+
+### 3.1 版本1（默认）
+直接发送 Opus 音频数据，无额外元数据。Websocket 协议会区分 text 与 binary。
+
+### 3.2 版本2
+使用 `BinaryProtocol2` 结构：
+```c
+struct BinaryProtocol2 {
+    uint16_t version;        // 协议版本
+    uint16_t type;           // 消息类型 (0: OPUS, 1: JSON)
+    uint32_t reserved;       // 保留字段
+    uint32_t timestamp;      // 时间戳（毫秒，用于服务器端AEC）
+    uint32_t payload_size;   // 负载大小（字节）
+    uint8_t payload[];       // 负载数据
+} __attribute__((packed));
+```
+
+### 3.3 版本3
+使用 `BinaryProtocol3` 结构：
+```c
+struct BinaryProtocol3 {
+    uint8_t type;            // 消息类型
+    uint8_t reserved;        // 保留字段
+    uint16_t payload_size;   // 负载大小
+    uint8_t payload[];       // 负载数据
+} __attribute__((packed));
+```
+
+---
+
+## 4. JSON 消息结构
+
+WebSocket 文本帧以 JSON 方式传输，以下为常见的 `"type"` 字段及其对应业务逻辑。若消息里包含未列出的字段，可能为可选或特定实现细节。
+
+### 4.1 设备端→服务器
+
+1. **Hello**  
+   - 连接成功后，由设备端发送，告知服务器基本参数。  
+   - 例：
+     ```json
+     {
+       "type": "hello",
+       "version": 1,
+       "features": {
+         "mcp": true
+       },
+       "transport": "websocket",
+       "audio_params": {
+         "format": "opus",
+         "sample_rate": 16000,
+         "channels": 1,
+         "frame_duration": 60
+       }
+     }
+     ```
+
+2. **Listen**  
+   - 表示设备端开始或停止录音监听。  
+   - 常见字段：  
+     - `"session_id"`：会话标识  
+     - `"type": "listen"`  
+     - `"state"`：`"start"`, `"stop"`, `"detect"`（唤醒检测已触发）  
+     - `"mode"`：`"auto"`, `"manual"` 或 `"realtime"`，表示识别模式。  
+   - 例：开始监听  
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "listen",
+       "state": "start",
+       "mode": "manual"
+     }
+     ```
+
+3. **Abort**  
+   - 终止当前说话（TTS 播放）或语音通道。  
+   - 例：
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "abort",
+       "reason": "wake_word_detected"
+     }
+     ```
+   - `reason` 值可为 `"wake_word_detected"` 或其他。
+
+4. **Wake Word Detected**  
+   - 用于设备端向服务器告知检测到唤醒词。
+   - 在发送该消息之前，可提前发送唤醒词的 Opus 音频数据，用于服务器进行声纹检测。  
+   - 例：
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "listen",
+       "state": "detect",
+       "text": "你好小明"
+     }
+     ```
+
+5. **MCP**
+   - 推荐用于物联网控制的新一代协议。所有设备能力发现、工具调用等均通过 type: "mcp" 的消息进行，payload 内部为标准 JSON-RPC 2.0（详见 [MCP 协议文档](./mcp-protocol.md)）。
+   
+   - **设备端到服务器发送 result 的例子：**
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "mcp",
+       "payload": {
+         "jsonrpc": "2.0",
+         "id": 1,
+         "result": {
+           "content": [
+             { "type": "text", "text": "true" }
+           ],
+           "isError": false
+         }
+       }
+     }
+     ```
+
+---
+
+### 4.2 服务器→设备端
+
+1. **Hello**  
+   - 服务器端返回的握手确认消息。  
+   - 必须包含 `"type": "hello"` 和 `"transport": "websocket"`。  
+   - 可能会带有 `audio_params`，表示服务器期望的音频参数，或与设备端对齐的配置。   
+   - 服务器可选下发 `session_id` 字段，设备端收到后会自动记录。  
+   - 成功接收后设备端会设置事件标志，表示 WebSocket 通道就绪。
+
+2. **STT**  
+   - `{"session_id": "xxx", "type": "stt", "text": "..."}`
+   - 表示服务器端识别到了用户语音。（例如语音转文本结果）  
+   - 设备可能将此文本显示到屏幕上，后续再进入回答等流程。
+
+3. **LLM**  
+   - `{"session_id": "xxx", "type": "llm", "emotion": "happy", "text": "😀"}`
+   - 服务器指示设备调整表情动画 / UI 表达。  
+
+4. **TTS**  
+   - `{"session_id": "xxx", "type": "tts", "state": "start"}`：服务器准备下发 TTS 音频，设备端进入 "speaking" 播放状态。  
+   - `{"session_id": "xxx", "type": "tts", "state": "stop"}`：表示本次 TTS 结束。  
+   - `{"session_id": "xxx", "type": "tts", "state": "sentence_start", "text": "..."}`
+     - 让设备在界面上显示当前要播放或朗读的文本片段（例如用于显示给用户）。  
+
+5. **MCP**
+   - 服务器通过 type: "mcp" 的消息下发物联网相关的控制指令或返回调用结果，payload 结构同上。
+   
+   - **服务器到设备端发送 tools/call 的例子：**
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "mcp",
+       "payload": {
+         "jsonrpc": "2.0",
+         "method": "tools/call",
+         "params": {
+           "name": "self.light.set_rgb",
+           "arguments": { "r": 255, "g": 0, "b": 0 }
+         },
+         "id": 1
+       }
+     }
+     ```
+
+6. **System**
+   - 系统控制命令，常用于远程升级更新。
+   - 例：
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "system",
+       "command": "reboot"
+     }
+     ```
+   - 支持的命令：
+     - `"reboot"`：重启设备
+
+7. **Custom**（可选）
+   - 自定义消息，当 `CONFIG_RECEIVE_CUSTOM_MESSAGE` 启用时支持。
+   - 例：
+     ```json
+     {
+       "session_id": "xxx",
+       "type": "custom",
+       "payload": {
+         "message": "自定义内容"
+       }
+     }
+     ```
+
+8. **音频数据：二进制帧**  
+   - 当服务器发送音频二进制帧（Opus 编码）时，设备端解码并播放。  
+   - 若设备端正在处于 "listening" （录音）状态，收到的音频帧会被忽略或清空以防冲突。
+
+---
+
+## 5. 音频编解码
+
+1. **设备端发送录音数据**  
+   - 音频输入经过可能的回声消除、降噪或音量增益后，通过 Opus 编码打包为二进制帧发送给服务器。  
+   - 根据协议版本，可能直接发送 Opus 数据（版本1）或使用带元数据的二进制协议（版本2/3）。
+
+2. **设备端播放收到的音频**  
+   - 收到服务器的二进制帧时，同样认定是 Opus 数据。  
+   - 设备端会进行解码，然后交由音频输出接口播放。  
+   - 如果服务器的音频采样率与设备不一致，会在解码后再进行重采样。
+
+---
+
+## 6. 常见状态流转
+
+以下为常见设备端关键状态流转，与 WebSocket 消息对应：
+
+1. **Idle** → **Connecting**  
+   - 用户触发或唤醒后，设备调用 `OpenAudioChannel()` → 建立 WebSocket 连接 → 发送 `"type":"hello"`。  
+
+2. **Connecting** → **Listening**  
+   - 成功建立连接后，若继续执行 `SendStartListening(...)`，则进入录音状态。此时设备会持续编码麦克风数据并发送到服务器。  
+
+3. **Listening** → **Speaking**  
+   - 收到服务器 TTS Start 消息 (`{"type":"tts","state":"start"}`) → 停止录音并播放接收到的音频。  
+
+4. **Speaking** → **Idle**  
+   - 服务器 TTS Stop (`{"type":"tts","state":"stop"}`) → 音频播放结束。若未继续进入自动监听，则返回 Idle；如果配置了自动循环，则再度进入 Listening。  
+
+5. **Listening** / **Speaking** → **Idle**（遇到异常或主动中断）  
+   - 调用 `SendAbortSpeaking(...)` 或 `CloseAudioChannel()` → 中断会话 → 关闭 WebSocket → 状态回到 Idle。

+  kDeviceStateSpeaking --> kDeviceStateIdle:结束说话
+```
+
+---
+
+## 7. 错误处理
+
+1. **连接失败**  
+   - 如果 `Connect(url)` 返回失败或在等待服务器 "hello" 消息时超时，触发 `on_network_error_()` 回调。设备会提示"无法连接到服务"或类似错误信息。
+
+2. **服务器断开**  
+   - 如果 WebSocket 异常断开，回调 `OnDisconnected()`：  
+     - 设备回调 `on_audio_channel_closed_()`  
+     - 切换到 Idle 或其他重试逻辑。
+
+---
+
+## 8. 其它注意事项
+
+1. **鉴权**  
+   - 设备通过设置 `Authorization: Bearer <token>` 提供鉴权，服务器端需验证是否有效。  
+   - 如果令牌过期或无效，服务器可拒绝握手或在后续断开。
+
+2. **会话控制**  
+   - 代码中部分消息包含 `session_id`，用于区分独立的对话或操作。服务端可根据需要对不同会话做分离处理。
+
+3. **音频负载**  
+   - 代码里默认使用 Opus 格式，并设置 `sample_rate = 16000`，单声道。帧时长由 `OPUS_FRAME_DURATION_MS` 控制，一般为 60ms。可根据带宽或性能做适当调整。为了获得更好的音乐播放效果，服务器下行音频可能使用 24000 采样率。
+
+4. **协议版本配置**  
+   - 通过设置中的 `version` 字段配置二进制协议版本（1、2 或 3）
+   - 版本1：直接发送 Opus 数据
+   - 版本2：使用带时间戳的二进制协议，适用于服务器端 AEC
+   - 版本3：使用简化的二进制协议
+
+5. **物联网控制推荐 MCP 协议**  
+   - 设备与服务器之间的物联网能力发现、状态同步、控制指令等，建议全部通过 MCP 协议（type: "mcp"）实现。原有的 type: "iot" 方案已废弃。
+   - MCP 协议可在 WebSocket、MQTT 等多种底层协议上传输，具备更好的扩展性和标准化能力。
+   - 详细用法请参考 [MCP 协议文档](./mcp-protocol.md) 及 [MCP 物联网控制用法](./mcp-usage.md)。
+
+6. **错误或异常 JSON**  
+   - 当 JSON 中缺少必要字段，例如 `{"type": ...}`，设备端会记录错误日志（`ESP_LOGE(TAG, "Missing message type, data: %s", data);`），不会执行任何业务。
+
+---
+
+## 9. 消息示例
+
+下面给出一个典型的双向消息示例（流程简化示意）：
+
+1. **设备端 → 服务器**（握手）
+   ```json
+   {
+     "type": "hello",
+     "version": 1,
+     "features": {
+       "mcp": true
+     },
+     "transport": "websocket",
+     "audio_params": {
+       "format": "opus",
+       "sample_rate": 16000,
+       "channels": 1,
+       "frame_duration": 60
+     }
+   }
+   ```
+
+2. **服务器 → 设备端**（握手应答）
+   ```json
+   {
+     "type": "hello",
+     "transport": "websocket",
+     "session_id": "xxx",
+     "audio_params": {
+       "format": "opus",
+       "sample_rate": 16000
+     }
+   }
+   ```
+
+3. **设备端 → 服务器**（开始监听）
+   ```json
+   {
+     "session_id": "xxx",
+     "type": "listen",
+     "state": "start",
+     "mode": "auto"
+   }
+   ```
+   同时设备端开始发送二进制帧（Opus 数据）。
+
+4. **服务器 → 设备端**（ASR 结果）
+   ```json
+   {
+     "session_id": "xxx",
+     "type": "stt",
+     "text": "用户说的话"
+   }
+   ```
+
+5. **服务器 → 设备端**（TTS开始）
+   ```json
+   {
+     "session_id": "xxx",
+     "type": "tts",
+     "state": "start"
+   }
+   ```
+   接着服务器发送二进制音频帧给设备端播放。
+
+6. **服务器 → 设备端**（TTS结束）
+   ```json
+   {
+     "session_id": "xxx",
+     "type": "tts",
+     "state": "stop"
+   }
+   ```
+   设备端停止播放音频，若无更多指令，则回到空闲状态。
+
+---
+
+## 10. 总结
+
+本协议通过在 WebSocket 上层传输 JSON 文本与二进制音频帧，完成功能包括音频流上传、TTS 音频播放、语音识别与状态管理、MCP 指令下发等。其核心特征：
+
+- **握手阶段**：发送 `"type":"hello"`，等待服务器返回。  
+- **音频通道**：采用 Opus 编码的二进制帧双向传输语音流，支持多种协议版本。  
+- **JSON 消息**：使用 `"type"` 为核心字段标识不同业务逻辑，包括 TTS、STT、MCP、WakeWord、System、Custom 等。  
+- **扩展性**：可根据实际需求在 JSON 消息中添加字段，或在 headers 里进行额外鉴权。
+
+服务器与设备端需提前约定各类消息的字段含义、时序逻辑以及错误处理规则，方能保证通信顺畅。上述信息可作为基础文档，便于后续对接、开发或扩展。
