Now I have a complete picture. Let me analyze the problem and design the solution:

**Current flow problems:**
1. In `setup()`, `g_wifi.begin()` triggers `_emitProvisionState("success")` → `g_mqtt.publishProvisionStatus("success", "")` is called. But at this point MQTT is NOT connected yet (it connects at line 411-413 after WiFi), so the message is effectively dropped (silently fails the `isConnected()` check).

2. When MQTT connects the first time in `setup()` (line 412), `publishOnline()` is NOT called. It's only called during reconnection in `mqtt_manager.cpp::loop()` line 179.

3. So on first boot after provisioning: provision success is lost, and online is never sent (until a reconnect happens).

**What the user wants:**
配网成功的提示要和 online 在一起发送 — when provisioning succeeds, the provision status and online notification should be sent together.

**My plan:**

1. Add a `publishOnline()` call after `g_mqtt.connect()` in `setup()`, so online is sent on initial connection.

2. After sending online, also send the provision status (if there was a recent provision success). Or better: modify `publishOnline()` to also include provision info, or add a new method that sends both.

Actually, a simpler approach:

1. In the provision state callback, instead of immediately publishing (which fails because MQTT isn't connected), we store the state.
2. After MQTT connects and publishes online, we also publish the stored provision state.
3. Or even simpler: merge the provision info into the online message.

Let me re-read the user's requirement: "每次配网成功，的提示要和online在一起发送"

This means: "Every time provisioning succeeds, the [provision] notification should be sent together with online."

The simplest approach:
1. Store the latest provision state
2. After MQTT connects (both initial and reconnect), send online + provision status together
3. Clear the stored provision state after sending

Or alternatively: merge the provision status field into the online JSON message.

I think the cleanest approach is:
1. In `MQTTManager`, add a way to send `publishOnline()` with an optional provision status
2. In `main.cpp` setup, after `g_mqtt.connect()`, call `g_mqtt.publishOnline()` (add this missing call)
3. Then also call `g_mqtt.publishProvisionStatus()` if applicable

Wait, actually looking at the flow again more carefully:

In `setup()`:
```
g_wifi.onProvisionState → g_mqtt.publishProvisionStatus  // callback registered
g_wifi.begin()  // This internally calls _connectWiFi() which calls _emitProvisionState("success")
                // The callback fires, but MQTT is not connected yet → message lost
...
g_mqtt.connect()  // Connects but doesn't call publishOnline()
```

The fix should be:
1. Make the provision callback store the state instead of publishing directly (since MQTT may not be connected)
2. After MQTT connects in setup(), publish online + stored provision state
3. Also handle this in the reconnect case in MQTT loop

Actually, a simpler approach: modify `publishOnline()` to also include a `provisionState` field when applicable. Or just ensure both are called in sequence after MQTT connects.

Let me think about what changes are minimal and clean:

**Approach: Store provision state, send both after MQTT connects**

1. Add a `_pendingProvisionState` string member to MQTTManager
2. Modify `publishProvisionStatus` to store the state if not connected
3. After connect (both initial and reconnect), publish online + pending provision
4. In `main.cpp` setup, call `publishOnline()` after `g_mqtt.connect()`

Actually, I think an even simpler approach for this specific use case:

1. In `main.cpp` setup, after `g_mqtt.connect()`, explicitly call `g_mqtt.publishOnline()` followed by `g_mqtt.publishProvisionStatus("success", "")` if needed.

But the problem is that in setup we don't know if provisioning just happened or if it's a normal boot...

Let me look at this from a different angle. The user wants provision status to be sent with online. The most natural way is:

1. In MQTTManager, add a `publishOnlineWithProvision(const char* provisionState)` method, or modify `publishOnline` to accept an optional provision state parameter.

OR

2. Simply ensure that after MQTT connects, both `publishOnline()` and `publishProvisionStatus()` are called in order.

I think the cleanest approach for "sent together" is to merge them into one message. Let me design the solution:

**Plan:**
1. Modify `MQTTManager` to store the last provision state string
2. Add a method `publishOnline()` that optionally includes provision info
3. In `main.cpp`, after MQTT connects, ensure online + provision are published
4. In `MQTTManager::loop()` reconnect, also send both

Actually, let me step back. The simplest interpretation: the user wants `publishProvisionStatus("success")` and `publishOnline()` to be sent together, meaning sequentially one after the other, at the same time — after MQTT is connected. Currently provision is "sent" (but actually dropped) before MQTT connects.

Let me implement it this way:

1. In `MQTTManager`, add a `_pendingProvision` flag and string
2. `publishProvisionStatus()` stores the state if MQTT isn't connected
3. In `main.cpp` setup, after `g_mqtt.connect()`, call `g_mqtt.publishOnline()` and flush any pending provision
4. Also handle in MQTTManager loop reconnection

Wait, I'm overcomplicating this. Let me think about what the code should look like:

In `main.cpp` setup:
```cpp
// 连接 MQTT
if (g_wifi.isConnected()) {
    g_mqtt.connect();
    g_mqtt.publishOnline();  // ← ADD: send online on initial connect
    g_mqtt.publishProvisionStatus("success", "");  // ← ADD: send provision success together with online
}
```

But this would always send provision success, even on normal reboot. That's not right.

Better approach: store a flag in a global or in WiFiMgmt that indicates whether this boot was a fresh provision.

Looking at the WiFi flow:
- `WiFiMgmt::begin()` → `_connectWiFi()` → if `autoConnect` succeeds and it was a fresh provision (user entered credentials → `_saveParamsCallback` was called), then it's a "fresh provision"
- If `autoConnect` succeeds with existing saved credentials, it's a "normal boot" → no provision

I could add a `wasFreshProvision()` method to WiFiMgmt, or use a different mechanism.

Actually, looking at the WiFiManager library behavior: `_saveParamsCallback` is ONLY called when the user clicks "Save" on the config portal page. So on a normal boot with saved credentials, `_saveParamsCallback` is NOT called. This gives us a way to detect fresh provisioning.

Let me add a `_freshProvision` flag to WiFiMgmt:
- Set to `true` in `_saveParamsCallback()`
- Checked via `isFreshProvision()` method
- Reset after consumption

Then in main.cpp setup:
```cpp
if (g_wifi.isConnected()) {
    g_mqtt.connect();
    g_mqtt.publishOnline();
    if (g_wifi.isFreshProvision()) {
        g_mqtt.publishProvisionStatus("success", "");
    }
}
```

Hmm, but there's a timing issue. The `_saveParamsCallback` is called DURING `_connectWiFi()`, which is called from `begin()`. And the provision "success" state is emitted from `_connectWiFi()` after `autoConnect` returns. So we need to track this correctly.

Let me trace through `_connectWiFi()`:
1. `_wm.autoConnect(...)` is called - blocking, shows config portal if needed
2. If user saves params → `_saveParamsCallback()` is called → saves to LittleFS
3. `autoConnect` returns true (WiFi connected)
4. `_emitProvisionState("success")` is called

So I need to:
1. In `_saveParamsCallback()`, set `_freshProvision = true`
2. After `begin()` returns, check `isFreshProvision()`
3. If true, publish both online and provision success together

Let me now write the plan and implement it.

Wait, actually there's another issue. Even after MQTT `connect()` returns true in setup, the connection might not be fully ready for publishing (the PubSubClient connect is synchronous though, so it should be fine).

Let me also check - does `g_mqtt.connect()` in setup actually succeed? The WiFi is connected at that point, and MQTT server is configured, so it should work.

OK here's my implementation plan:

### Changes needed:

1. **`wifi_manager.h`** - Add `_freshProvision` flag and `isFreshProvision()` getter
2. **`wifi_manager.cpp`** - Set `_freshProvision = true` in `_saveParamsCallback()` and in `startConfigPortal()` success path
3. **`main.cpp`** - After MQTT connect in setup, publish online + provision success (if fresh provision)
4. **`main.cpp`** - Also add `publishOnline()` call on initial connect (currently missing)

Actually, wait. Let me also consider another flow: `startConfigPortal()` (manual trigger). This also does a provision flow. Let me handle that too.

Actually, for `startConfigPortal()`, it's called from the button long press handler, and after it completes, we'd need to reconnect MQTT too. But that's a separate concern — let me focus on the main flow.

Let me also reconsider: the `_emitProvisionState` callback in main.cpp is registered BEFORE `g_wifi.begin()`. So during `begin()`, when "success" is emitted, it tries to publish via MQTT which isn't connected yet. The fix for this specific issue:

Option 1: Make `publishProvisionStatus` queue the message if not connected
Option 2: Move the callback registration to after MQTT is connected
Option 3: In the callback, check if MQTT is connected, and if not, store for later

I think a combination is cleanest:
- Add a `_pendingProvision` flag to MQTTManager
- When `publishProvisionStatus` is called but not connected, store the state
- When `publishOnline()` is called, also flush any pending provision
- In setup(), after MQTT connects, call `publishOnline()` which will also flush pending provision

This way:
- During WiFi.begin() → emit "success" → publishProvisionStatus called → MQTT not connected → stored as pending
- After MQTT.connect() → publishOnline() → also flushes pending provision → both sent together

Let me implement this.

Actually, thinking about it even more, I think the simplest approach that achieves exactly what the user wants:

1. Add `_pendingProvision` string to MQTTManager
2. Modify `publishProvisionStatus` to store state if not connected
3. Modify `publishOnline` to accept optional provision info, or just have a method that sends both
4. Call it after MQTT connects

Let me go with a slightly different approach to keep it really clean:

1. In `MQTTManager`, add a `publishOnline(const char* provisionState = nullptr)` optional parameter
2. If provisionState is provided, include it in the online JSON
3. In main.cpp, track whether a fresh provision happened, and pass it to publishOnline

Actually that couples things too much. Let me just do:

1. In `main.cpp`, after `g_mqtt.connect()`, explicitly call `g_mqtt.publishOnline()`
2. Also call `g_mqtt.publishProvisionStatus()` if we just provisioned
3. Add `isFreshProvision()` to WiFiMgmt

Let me just implement it now.

Wait, one more consideration. The `_emitProvisionState("success")` in `_connectWiFi()` is called at line 214, AFTER `autoConnect` succeeded. But `_saveParamsCallback` (which indicates user saved params) is called DURING `autoConnect`. So by the time we check `isFreshProvision()` after `begin()`, the flag would be set.

But there's another path: normal boot with existing WiFi credentials. `autoConnect` succeeds, `_saveParamsCallback` is NOT called, but `_emitProvisionState("success")` IS called (line 136 in begin, and line 214 in _connectWiFi). In this case, `isFreshProvision()` should return false.

So:
- Fresh provision → `_saveParamsCallback` called → `_freshProvision = true` → `_emitProvisionState("success")` → callback publishes (but MQTT not connected)
- Normal boot → `_saveParamsCallback` NOT called → `_freshProvision = false` → `_emitProvisionState("success")` → callback publishes (but MQTT not connected)

Both cases have the same MQTT-not-connected problem. The user specifically wants provision success + online together.

Let me simplify my approach:

**Implementation:**

1. **`wifi_manager.h`**: Add `bool _freshProvision` and getter `isFreshProvision()`
2. **`wifi_manager.cpp`**: Set `_freshProvision = true` in `_saveParamsCallback()`
3. **`main.cpp`**:
   - After `g_mqtt.connect()`, always call `g_mqtt.publishOnline()`
   - If `g_wifi.isFreshProvision()`, also call `g_mqtt.publishProvisionStatus("success", "")` right after
   - Remove the provision callback registration before WiFi begin (since it's useless — MQTT not connected). Actually, keep it for states like "ready" and "wifi_failed", but handle "success" specially.

Hmm, actually, let me reconsider. The provision callback is useful for states other than "success":
- "ready" — MQTT might not be connected, but it informs the server that device entered provisioning mode
- "wifi_failed" — MQTT might not be connected either

Actually, "ready" is emitted when entering AP mode (WiFi disconnected), so MQTT definitely won't be connected. And "wifi_failed" also means WiFi failed, so MQTT won't be connected either.

So the provision callback is basically never useful in its current form because MQTT is never connected when these states are emitted. But that's a separate issue — the user specifically asked about "success" + "online" together.

Let me just implement the fix:

1. Add `_freshProvision` to WiFiMgmt
2. After MQTT connect in setup, send online + provision success together if fresh provision
3. Also add the missing `publishOnline()` for initial connection

Let me code this up now.

Now let me implement the changes. Let me start with the WiFi manager changes.


现在清楚了。当前流程有两个问题：

1. **配网 success 在 MQTT 连接之前发送** → 消息丢失
2. **首次 MQTT 连接后没有发 `publishOnline()`** → online 只在重连时发

下面开始修改，让配网成功后，online 和 provision 消息一起发送。

### 2. 在保存参数回调中标记新配网


    _instance->_saveConfig();

    Serial.println(F("[WiFi] 📋 新配置:"));

    _instance->_saveConfig();
    _instance->_freshProvision = true;  // 标记刚完成配网

    Serial.println(F("[WiFi] 📋 新配置:"));


The file d:\PlatformIO1\Projects\Healthv2.0\src\wifi_manager.cpp has been updated successfully. (file state is current in your context — no need to Read it back)

    _instance->_saveConfig();

    Serial.println(F("[WiFi] 📋 新配置:"));

    _instance->_saveConfig();
    _instance->_freshProvision = true;  // 标记刚完成配网

    Serial.println(F("[WiFi] 📋 新配置:"));

+    _instance->_freshProvision = true;  // 标记刚完成配网


Now update the `main.cpp` setup to:
1. After MQTT connects, call publishOnline() on initial connection
2. If fresh provision, also call publishProvisionStatus("success") right after
3. Also need to make the provision callback smarter — for "success" state, don't try to publish (since we handle it in setup), but for other states, still try

Actually, now that we have `isFreshProvision()`, the flow should be:
- During `g_wifi.begin()`, the provision "success" callback fires but MQTT isn't connected → we could let it try and fail silently, OR we can skip it
- After `g_mqtt.connect()` in setup, we explicitly send online + provision success

The cleanest approach for the callback: keep it as-is, because `publishProvisionStatus` already checks `isConnected()` and silently returns if not connected. Then after MQTT connects, we explicitly send both.

Let me update main.cpp.


### 3. 修改 main.cpp setup — MQTT 连接后同时发送 online + provision


    // 连接 MQTT

    // 连接 MQTT
    if (g_wifi.isConnected()) {
        g_mqtt.connect();
    }

    // 连接 MQTT
    if (g_wifi.isConnected()) {

        // 新配网成功: provision success 与 online 一起发送

+        if (g_wifi.isFreshProvision()) {

+            g_mqtt.publishProvisionStatus("success", "");


Now let me update the todo list and verify the changes. Let me also double-check that the `startConfigPortal()` path also works. In `startConfigPortal()`, it calls `_wm.startConfigPortal()`, which if user saves params, will call `_saveParamsCallback()` → sets `_freshProvision = true`. But `startConfigPortal()` is called from a button long press, and after it returns, the main loop continues. The difference is that in this path, MQTT might already be connected.

But looking at main.cpp, the button handler for provision long press calls `g_wifi.startConfigPortal()`. During `startConfigPortal()`:
1. WiFi disconnects (enters AP mode)
2. User configures
3. `_saveParamsCallback()` is called → `_freshProvision = true`
4. `startConfigPortal()` exits
5. Back in button handler

After this, WiFi is reconnected with new credentials. But the MQTT connection would be broken (server might have changed). The main loop should handle reconnection, and when reconnecting in `MQTTManager::loop()`, it calls `publishOnline()` (line 179 of mqtt_manager.cpp).

But the provision success message won't be sent in this case because we only check `isFreshProvision()` in setup().

Hmm, the user specifically mentioned "每次配网成功" (every time provisioning succeeds), so we should also handle the `startConfigPortal()` path.

Let me think about how to handle this...

Option 1: In the main loop, detect when MQTT reconnects after a fresh provision
Option 2: In `startConfigPortal()`, after WiFi reconnects, reconnect MQTT and send both messages
Option 3: In the provision state callback for "success", if MQTT is connected, send both

I think the cleanest approach is to handle it in the MQTT loop — after a fresh provision, when MQTT reconnects, also send provision success. But this requires the flag to persist until consumed.

Actually, let me handle it differently. The `startConfigPortal()` changes WiFi credentials (potentially MQTT too), so after it returns:
1. WiFi is connected with new settings
2. But MQTT may be disconnected (old connection dropped)
3. We need to reconfigure MQTT with potentially new settings and reconnect

Looking at main.cpp, after `startConfigPortal()` returns, the button handler just returns to the main loop. The main loop calls `g_wifi.loop()` (WiFi is connected), then `g_mqtt.loop()` which will attempt reconnection. When it reconnects, it calls `publishOnline()`.

So I should add logic: after MQTT reconnects in the loop, if `g_wifi.isFreshProvision()`, also send provision success.

Let me modify the main loop to handle this:

```cpp
if (g_mqtt.isConnected()) {
    if (wasDisconnected) {
        syncTime();
        // After reconnection, also check if fresh provision
        if (g_wifi.isFreshProvision()) {
            g_mqtt.publishProvisionStatus("success", "");
        }
        wasDisconnected = false;
    }
}
```

Wait, but `_freshProvision` is a one-time flag. After we consume it in setup, it'll still be true in the loop. We should clear it after consumption. Or we can just use it as-is since it'll stay true for the entire session, which means provision success would be sent on every reconnect. That's not ideal.

Better: add a method to consume the flag, or clear it after use. Let me add a `clearFreshProvision()` or just set it in the provision success send path.

Actually, let me think about it differently. The flag is `_freshProvision`. It gets set when user saves params. It should be cleared after we successfully send the "provision success + online" combo. Let me add a clear method.


还需要处理 `startConfigPortal()` 手动配网的路径。让我添加清除标志的方法，并在主循环中也处理重连后的发送。

Now I need to also handle the main loop reconnection case. When `startConfigPortal()` is called from a button long press, after it completes, the main loop will detect MQTT disconnected and reconnect. When it reconnects, we need to send provision success + online together.

Let me update the main loop to handle this case.


现在处理主循环中 `startConfigPortal()` 后的重连场景。


        // WiFi 刚连上但 MQTT 还没连
        static bool wasDisconnected = true;
        if (g_mqtt.isConnected()) {
            if (wasDisconnected) {
                // 刚恢复连接, 同步时间
                syncTime();
                wasDisconnected = false;
            }

        // WiFi 刚连上但 MQTT 还没连
        static bool wasDisconnected = true;
        if (g_mqtt.isConnected()) {
            if (wasDisconnected) {
                // 刚恢复连接, 同步时间
                syncTime();
                // 重连成功也发送 online
                g_mqtt.publishOnline();
                // 新配网成功: provision success 与 online 一起发送
                if (g_wifi.isFreshProvision()) {
                    g_mqtt.publishProvisionStatus("success", "");
                    g_wifi.clearFreshProvision();
                }
                wasDisconnected = false;
            }


        // WiFi 刚连上但 MQTT 还没连
        static bool wasDisconnected = true;
        if (g_mqtt.isConnected()) {
            if (wasDisconnected) {
                // 刚恢复连接, 同步时间
                syncTime();
                wasDisconnected = false;
            }

        // WiFi 刚连上但 MQTT 还没连
        static bool wasDisconnected = true;
        if (g_mqtt.isConnected()) {
            if (wasDisconnected) {
                // 刚恢复连接, 同步时间
                syncTime();
                // 重连成功也发送 online
                g_mqtt.publishOnline();
                // 新配网成功: provision success 与 online 一起发送
                if (g_wifi.isFreshProvision()) {
                    g_mqtt.publishProvisionStatus("success", "");
                    g_wifi.clearFreshProvision();
                }
                wasDisconnected = false;
            }

// 刚恢复连接, 同步时间

+                g_mqtt.publishOnline();

+                // 新配网成功: provision success 与 online 一起发送

+                if (g_wifi.isFreshProvision()) {

+                    g_mqtt.publishProvisionStatus("success", "");

+                    g_wifi.clearFreshProvision();


Now I also need to handle the `startConfigPortal()` case properly. When `startConfigPortal()` is called from the button handler:
1. It blocks in `_wm.startConfigPortal()`
2. If user saves params, `_saveParamsCallback()` sets `_freshProvision = true`
3. After portal exits, WiFi connects with new credentials
4. Back in main loop, MQTT detects disconnect, reconnects, sends online + provision

But there's a problem: after `startConfigPortal()`, the MQTT config may have changed (different server/port/user/pass). The MQTT manager needs to be updated with new config. Let me check the button handler:

```cpp
g_buttons.onProvisionLongPress([]() {
    g_wifi.startConfigPortal();
});
```

After `startConfigPortal()` returns, the main loop continues. But MQTT still has the old server config. We need to update MQTT config from the new WiFi config.

Actually, I should update the button handler to reconfigure MQTT after `startConfigPortal()`. Let me read the current button handler in main.cpp and update it.

Also, I should consider: does `startConfigPortal()` change WiFi? If the user saves new WiFi credentials, the device reconnects to the new WiFi. If MQTT server settings also changed, we need to update those too.

Let me update the provision long press handler.


还需要更新 `startConfigPortal()` 按钮回调——配网后 MQTT 配置可能变了，需要重新设置。


374	    // 4. 按钮
375	    g_buttons.begin();
376	    g_buttons.onPageSwitch([]() {
377	        g_display.nextPage();
378	    });
379	    g_buttons.onAlarmDismiss([]() {
380	        g_alarm.clearAllLocal();
381	        g_radar.clearFall();  // 数据也归零
382	    });
383	    g_buttons.onProvisionLongPress([]() {
384	        g_wifi.startConfigPortal();
385	    });
386
387	    // 5. WiFi (WiFiManager 配网)
388	    // 先注册配网状态回调, 再 begin(), 这样配网过程中的 ready/success 都不会丢失

    // 4. 按钮
    g_buttons.begin();
    g_buttons.onPageSwitch([]() {
        g_display.nextPage();
    });
    g_buttons.onAlarmDismiss([]() {
        g_alarm.clearAllLocal();
        g_radar.clearFall();  // 数据也归零
    });

    });

    // 5. WiFi (WiFiManager 配网)
    // 先注册配网状态回调, 再 begin(), 这样配网过程中的 ready/success 都不会丢失


I need to update the provision long press handler to also reconfigure MQTT after the portal completes, since MQTT server settings may have changed. Let me update the callback.


    g_buttons.onProvisionLongPress([]() {
        g_wifi.startConfigPortal();
    });

    g_buttons.onProvisionLongPress([]() {
        g_wifi.startConfigPortal();
        // 配网后 MQTT 配置可能已更新, 重新设置并重连
        DeviceConfig cfg = g_wifi.getConfig();
        g_mqtt.setServer(cfg.mqtt_server, atoi(cfg.mqtt_port),
                         cfg.mqtt_user, cfg.mqtt_pass);
        g_mqtt.begin(cfg.device_id);
        g_mqtt.connect();
        g_mqtt.publishOnline();
        if (g_wifi.isFreshProvision()) {
            g_mqtt.publishProvisionStatus("success", "");
            g_wifi.clearFreshProvision();
        }
    });


    g_buttons.onProvisionLongPress([]() {
        g_wifi.startConfigPortal();
    });

    g_buttons.onProvisionLongPress([]() {
        g_wifi.startConfigPortal();
        // 配网后 MQTT 配置可能已更新, 重新设置并重连
        DeviceConfig cfg = g_wifi.getConfig();
        g_mqtt.setServer(cfg.mqtt_server, atoi(cfg.mqtt_port),
                         cfg.mqtt_user, cfg.mqtt_pass);
        g_mqtt.begin(cfg.device_id);
        g_mqtt.connect();
        g_mqtt.publishOnline();
        if (g_wifi.isFreshProvision()) {
            g_mqtt.publishProvisionStatus("success", "");
            g_wifi.clearFreshProvision();
        }
    });

+        // 配网后 MQTT 配置可能已更新, 重新设置并重连

+        DeviceConfig cfg = g_wifi.getConfig();

+        g_mqtt.setServer(cfg.mqtt_server, atoi(cfg.mqtt_port),

Everything looks good. Let me verify the complete flow now:

**Path 1: 首次启动 + 新配网 (用户通过配网页面输入WiFi)**
1. `setup()` → `g_wifi.begin()` → `_connectWiFi()` → `autoConnect()` → 用户输入并保存 → `_saveParamsCallback()` 设置 `_freshProvision = true` → WiFi连接成功
2. `g_wifi.begin()` 返回
3. `g_mqtt.connect()` → 连接成功
4. `g_mqtt.publishOnline()` ✅ (新增)
5. `g_wifi.isFreshProvision()` → true → `g_mqtt.publishProvisionStatus("success", "")` ✅ (新增)
6. `g_wifi.clearFreshProvision()` ✅

→ online + provision success 一起发出 ✅

**Path 2: 正常重启 (使用已有WiFi配置)**
1. `setup()` → `g_wifi.begin()` → `_connectWiFi()` → `autoConnect()` → 自动连接成功（无需用户输入，`_saveParamsCallback` 不触发）
2. `g_wifi.begin()` 返回, `_freshProvision = false`
3. `g_mqtt.connect()` → 连接成功
4. `g_mqtt.publishOnline()` ✅ (新增，之前缺失的首次online)
5. `g_wifi.isFreshProvision()` → false → 不发送 provision

→ 只发 online ✅

**Path 3: 手动配网 (长按按钮触发 startConfigPortal)**
1. `startConfigPortal()` → `_wm.startConfigPortal()` → 用户输入并保存 → `_saveParamsCallback()` 设置 `_freshProvision = true` → WiFi连接成功
2. 重新配置MQTT (新服务器地址可能变了)
3. `g_mqtt.connect()` → 连接成功
4. `g_mqtt.publishOnline()` ✅
5. `g_wifi.isFreshProvision()` → true → `g_mqtt.publishProvisionStatus("success", "")` ✅
6. `g_wifi.clearFreshProvision()` ✅

→ online + provision success 一起发出 ✅

**Path 4: MQTT意外断开后重连**
1. 主循环检测到断开 → `MQTTManager::loop()` 自动重连
2. `g_mqtt.loop()` 连接成功后 `wasDisconnected` 检测到恢复
3. `g_mqtt.publishOnline()` ✅ (这里MQTTManager::loop()内部也发了一次，但重复发online问题不大)
4. `g_wifi.isFreshProvision()` → false（正常重连不是配网）→ 不发送 provision

Wait, there's a double-publish of online in the reconnect case:
- `MQTTManager::loop()` line 179: `publishOnline()` is called after reconnect
- `main.cpp` loop: also calls `publishOnline()` when wasDisconnected detected

This is a minor issue but not harmful. However, I should clean this up. Let me remove the `publishOnline()` from `MQTTManager::loop()` since main.cpp already handles it.

Actually wait, let me re-read the MQTT loop code:

```cpp
void MQTTManager::loop() {
    ...
    if (!_connected) {
        ...
        if (connect()) {
            publishOnline();  // line 179 - sends online on reconnect
            ...
        }
    }
    ...
}
```

And in main.cpp loop:
```cpp
if (wifiOk) {
    g_mqtt.loop();  // This will internally call publishOnline on reconnect

    static bool wasDisconnected = true;
    if (g_mqtt.isConnected()) {
        if (wasDisconnected) {
            ...
            g_mqtt.publishOnline();  // My new addition - duplicate!
            ...
        }
    }
}
```

So yes, on reconnection there will be two `publishOnline()` calls. But this was also the case before my change — the `publishOnline()` in MQTTManager::loop() was already there. My addition just adds another one explicitly in main.cpp.

I should remove the `publishOnline()` from `MQTTManager::loop()` since main.cpp now handles it in a more centralized way. Or I could remove it from main.cpp instead.

Actually, the cleaner approach: keep `publishOnline()` only in `MQTTManager::loop()` for the reconnect case. In main.cpp, handle it only for the "transition from disconnected to connected" detection (which includes the initial connect), and also add the provision check there.

But the problem is that `MQTTManager::loop()`'s `publishOnline()` doesn't know about provision state. So I should either:
1. Remove `publishOnline()` from `MQTTManager::loop()` and keep it only in main.cpp's `wasDisconnected` block
2. Or add provision awareness to MQTTManager

Option 1 is simpler. `MQTTManager::loop()` handles the reconnect, but the `publishOnline()` and provision logic lives in main.cpp's `wasDisconnected` detection.

Let me remove the `publishOnline()` from `MQTTManager::loop()` to avoid the duplicate.


有个重复发送 online 的问题——`MQTTManager::loop()` 重连时内部也发了一次 `publishOnline()`，和 main.cpp 主循环中的重复了。清理掉内部的，统一由 main.cpp 管理。


169	void MQTTManager::loop() {
170	    static uint32_t lastStatusLog = 0;
171
172	    if (!_connected) {
173	        uint32_t now = millis();
174	        if (now - _lastReconnectAttempt >= _reconnectInterval) {
175	            _lastReconnectAttempt = now;
176	            Serial.printf("[MQTT] 🔄 尝试重连 (已等%ds)\n",
177	                          _reconnectInterval / 1000);
178	            if (connect()) {
179	                publishOnline();  // 上线通知
180	                Serial.println(F("[MQTT] 🔄 重连成功!"));
181	            }
182	        }
183	    } else {

void MQTTManager::loop() {
    static uint32_t lastStatusLog = 0;

    if (!_connected) {
        uint32_t now = millis();
        if (now - _lastReconnectAttempt >= _reconnectInterval) {
            _lastReconnectAttempt = now;
            Serial.printf("[MQTT] 🔄 尝试重连 (已等%ds)\n",
                          _reconnectInterval / 1000);
            if (connect()) {
                publishOnline();  // 上线通知
                Serial.println(F("[MQTT] 🔄 重连成功!"));
            }
        }
    } else {


I'll remove `publishOnline()` from `MQTTManager::loop()` since main.cpp handles it in the `wasDisconnected` detection block, which also checks for fresh provision.


Edit

            if (connect()) {
                publishOnline();  // 上线通知
                Serial.println(F("[MQTT] 🔄 重连成功!"));
            }

            if (connect()) {
                // online 由 main.cpp 统一发送 (含配网状态)
                Serial.println(F("[MQTT] 🔄 重连成功!"));
            }


The file d:\PlatformIO1\Projects\Healthv2.0\src\mqtt_manager.cpp has been updated successfully. (file state is current in your context — no need to Read it back)

            if (connect()) {
                publishOnline();  // 上线通知
                Serial.println(F("[MQTT] 🔄 重连成功!"));
            }

            if (connect()) {
                // online 由 main.cpp 统一发送 (含配网状态)
                Serial.println(F("[MQTT] 🔄 重连成功!"));
            }

Serial.printf("[MQTT] 🔄 尝试重连 (已等%ds)\n",

-                publishOnline();  // 上线通知

+                // online 由 main.cpp 统一发送 (含配网状态)


Now let me verify the complete final state by reading the main.cpp changes to make sure everything is coherent. Let me also verify the full modified files don't have issues.

修改完成。来看下所有改动的总结：

---

## 改动总结

### 问题
配网成功 (`provision success`) 消息在 MQTT 连接之前就发送了，导致消息丢失；首次 MQTT 连接也没有发 `online` 通知。

### 修改了 4 个文件

| 文件 | 改动 |
|------|------|
| [include/wifi_manager.h](include/wifi_manager.h#L84-L89) | 新增 `isFreshProvision()` / `clearFreshProvision()` 方法和 `_freshProvision` 成员 |
| [src/wifi_manager.cpp](src/wifi_manager.cpp#L398) | `_saveParamsCallback()` 中标记 `_freshProvision = true` |
| [src/mqtt_manager.cpp](src/mqtt_manager.cpp#L178-L179) | 移除 `loop()` 重连中的 `publishOnline()`，统一由 main.cpp 管理 |
| [src/main.cpp](src/main.cpp) | 3 处改动（见下方） |

### main.cpp 的 3 条发送路径

**① setup() 首次连接** ([main.cpp:424-430](src/main.cpp#L424-L430))：
```
g_mqtt.connect() → publishOnline() → (if freshProvision) publishProvisionStatus("success")
```

**② 主循环 MQTT 恢复连接** ([main.cpp:468-476](src/main.cpp#L468-L476))：
```
wasDisconnected=true → publishOnline() → (if freshProvision) publishProvisionStatus("success")
```

**③ 手动配网按钮** ([main.cpp:383-395](src/main.cpp#L383-L395))：
```
startConfigPortal() → 更新MQTT配置 → connect() → publishOnline() → (if freshProvision) publishProvisionStatus("success")
```

### 效果
- ✅ 新配网：`provision success` + `online` 一起发出
- ✅ 正常重启：只发 `online`（不发 provision）
- ✅ 手动配网：同样一起发出
- ✅ 断线重连：只发 `online`（不发 provision）


在雷达接入5v的磁珠，需要多少om


The user is asking about a ferrite bead (磁珠) for the radar's 5V power supply line. They want to know what impedance (Ω) value to use.

This is an electronics/hardware question about power supply filtering for a radar module. The R60ABD1 is a 60GHz millimeter wave radar module. Let me think about this:

Ferrite beads on power lines are used for EMI/noise filtering. For a radar module like the R60ABD1:

1. The radar operates at 60GHz, so it's sensitive to power supply noise
2. The bead should filter high-frequency noise while allowing DC to pass
3. Key considerations:
   - Current draw of the radar module
   - Frequency range to suppress
   - DC resistance (should be low to avoid voltage drop)

For the R60ABD1 radar module:
- Operating voltage: 5V
- Current consumption: typically around 200-300mA (peak maybe higher)
- The noise frequency of concern would be in the MHz-GHz range

Typical ferrite bead recommendations for such applications:
- Impedance: 30Ω to 120Ω at 100MHz is common for power lines
- For sensitive RF/radar modules, 60Ω to 120Ω @ 100MHz is typical
- DC resistance should be very low (< 0.1Ω preferably)
- Rated current should be at least 2x the expected current draw

For the R60ABD1 specifically:
- A bead with 60Ω-120Ω @ 100MHz would be appropriate
- Common choices: 60Ω, 80Ω, or 120Ω @ 100MHz
- Package size: 0603 or 0805
- Current rating: ≥500mA

But I should look at the project code to see if there are any references to the radar power requirements, and also check if there's any existing power filtering design mentioned.

Actually, this is a hardware design question. Let me look at the project to see if there are any schematics or hardware design files.


这是一个硬件设计问题。让我先看看项目中是否有相关的硬件设计文件或雷达数据手册信息。

The project doesn't have hardware design files (schematics, PCB, etc.). Let me check the radar protocol header and radar manager to understand the radar module better, and then provide a well-reasoned answer about the ferrite bead selection.

Let me also check the platformio.ini for any clues about the hardware configuration.

The project doesn't have hardware schematics. The user is asking about ferrite bead selection for the R60ABD1 radar's 5V power line. This is a practical hardware design question about EMI filtering.

Let me provide a comprehensive answer based on general RF/power integrity design principles, specifically for the R60ABD1 60GHz millimeter wave radar module.

Key considerations for ferrite bead selection:

1. **Radar current consumption**: R60ABD1 60GHz radar typically draws about 150-300mA at 5V (typical operating current), with possibly higher peak during startup.

2. **Noise frequency to suppress**:
   - The radar operates at 60GHz RF
   - Digital switching noise from MCU (ESP32-S3) is in the MHz range
   - Power supply ripple from DC-DC converters is typically 100kHz-2MHz
   - The bead should be effective at the noise frequencies

3. **Ferrite bead parameters**:
   - **Impedance @ 100MHz**: This is the standard reference frequency for ferrite beads
   - **DC Resistance (DCR)**: Should be minimal to avoid voltage drop
   - **Rated current**: Must exceed the radar's peak current
   - **Frequency response**: Should be resistive (lossy) at noise frequencies, not inductive

For a 5V radar power supply line:

**Recommended: 60Ω to 120Ω @ 100MHz**

Specific recommendations:
- **60Ω @ 100MHz** (e.g., BLM18KG601SN1, BLM21PG600SN1) — Good general purpose, lower DCR
- **120Ω @ 100MHz** (e.g., BLM18KG121SN1, BLM21PG121SN1) — Better noise suppression
- **30Ω @ 100MHz** — If power supply is already clean, minimal impedance

For R60ABD1 specifically:
- The radar has its own internal LDO/regulation
- Main concern is preventing the radar's RF noise from coupling back to the ESP32, and preventing MCU/PSU noise from affecting radar sensitivity
- 60Ω @ 100MHz is a good starting point
- 120Ω if the power supply is noisy (e.g., shared with other loads)

Common part numbers:
- Murata BLM18KG601SN1: 60Ω @ 100MHz, 0603, 3A, DCR 0.05Ω
- Murata BLM21PG600SN1: 60Ω @ 100MHz, 0805, 4A, DCR 0.02Ω
- TDK MMZ1608S601A: 60Ω @ 100MHz, 0603, 1A, DCR 0.15Ω
- Murata BLM18KG121SN1: 120Ω @ 100MHz, 0603, 3A, DCR 0.05Ω

Additional recommendation:
- Add a 10µF + 0.1µF ceramic capacitor pair AFTER the ferrite bead (forming a Pi filter or LC filter)
- The bead plus capacitors form a low-pass filter

Let me provide this as a clear, practical answer.


项目中没有硬件原理图，不过根据 R60ABD1 毫米波雷达的特性和电源滤波设计经验，给你直接建议：

---

## 雷达 5V 磁珠选型建议

### 推荐值：**60Ω ~ 120Ω @ 100MHz**

100MHz 是磁珠阻抗的标准参考频率，实际选型请关注以下参数：

### 关键参数

| 参数 | 要求 | 说明 |
|------|------|------|
| **阻抗 @100MHz** | 60Ω~120Ω | 60Ω够用，电源噪声大选120Ω |
| **DCR (直流电阻)** | ≤0.1Ω | 越小越好，避免压降 |
| **额定电流** | ≥500mA | R60ABD1 工作电流约150~300mA，留余量 |
| **封装** | 0603 或 0805 | 手工焊接选0805方便些 |

### 具体参考型号

```
首选: Murata BLM18KG601SN1
     60Ω@100MHz / 0603 / 3A / DCR 0.05Ω

备选: TDK MMZ1608S601A
     60Ω@100MHz / 0603 / 1A / DCR 0.15Ω

噪声较大: Murata BLM21PG121SN1
          120Ω@100MHz / 0805 / 4A / DCR 0.02Ω
```

### 电路建议

```
5V_IN ──┬──[磁珠 60Ω]──┬── 5V_RADAR
        │               │
      10µF           10µF + 0.1µF
        │               │
       GND             GND
```

磁珠前后各放一个 10µF 陶瓷电容 + 后端并一个 0.1µF 高频去耦电容，组成 **CLC π型滤波**，对 60GHz 雷达的电源噪声抑制效果更好。

### 为什么选 60Ω？

- R60ABD1 内部自带 LDO 稳压，外部电源不需要极致的纹波抑制
- 阻抗过大（≥300Ω）会导致磁珠在低频段呈感性，容易和电容产生谐振反而放大噪声
- 60Ω 的 DCR 通常更低（~0.05Ω），300mA 电流下压降仅 15mV，基本不影响雷达工作
- 主要目的是阻止雷达的 RF 噪声反向耦合到 ESP32-S3 的电源轨

The user is asking where the WiFi provisioning interface code is. They can see the code in wifi_manager.cpp, but they might be asking about the actual HTML/webpage that gets shown during provisioning. The WiFiManager library by tzapu generates this HTML automatically on the ESP32. The captive portal HTML is built into the WiFiManager library itself, not in the project code.

Let me explain this clearly - the project uses the tzapu/WiFiManager library which provides a built-in captive portal web interface. The project only configures the parameters and custom styling via the code they've already seen.

However, if the user wants to further customize the page, they can use `_wm.setCustomHeadElement()` which is already being used at line 78-83 for font styling. They could also override the entire page template using WiFiManager's `setCustomMenuHTML` or similar methods.

Let me also check if there's anything more in the library itself.


配网界面的 HTML 页面代码**不在项目里**，是由 `tzapu/WiFiManager` 库**自动生成**的。

### 项目能控制的部分

全部在 [src/wifi_manager.cpp](src/wifi_manager.cpp#L74-L115) 这一个文件里：

| 代码位置 | 作用 |
|----------|------|
| 第77行 `setTitle()` | 页面标题：`🏥 五劳无感康养监测 - 设备配网` |
| 第78-83行 `setCustomHeadElement()` | 注入自定义 CSS（中文字体、字号） |
| 第90-115行 `addParameter()` | 添加 6 个自定义输入框（MQTT服务器/端口/用户名/密码/设备名/环境备注） |

WiFiManager 的配网页面是在 ESP32 内部由 C++ 代码动态拼出的 HTML 字符串，大概是这样的结构：

```
┌──────────────────────────────────────┐
│  🏥 五劳无感康养监测 - 设备配网       │  ← setTitle()
│                                      │
│  WiFi 名称: [________________]       │  ← 自动扫描SSID列表
│  WiFi 密码: [________________]       │  ← 库自动生成
│                                      │
│  MQTT 服务器地址: [______________]   │  ← _param_mqtt_server
│  MQTT 端口:       [______]          │  ← _param_mqtt_port
│  MQTT 用户名:     [______________]   │  ← _param_mqtt_user
│  MQTT 密码:       [______________]   │  ← _param_mqtt_pass
│  设备名称:        [______________]   │  ← _param_device_id
│  🏠 环境备注:     [______________]   │  ← _param_env_note
│                                      │
│  [保存]                              │  ← 触发 _saveParamsCallback()
└──────────────────────────────────────┘
```

### 如果想深度自定义页面

WiFiManager 还支持几个定制方法（在 [wifi_manager.cpp](src/wifi_manager.cpp) 中添加即可）：

```cpp
_wm.setCustomHeadElement("<style>/* CSS */</style>");   // 已有
_wm.setCustomMenuHTML("<script>/* JS */</script>");       // 注入JS
```

库的完整页面模板在 `.pio/libdeps/esp32-s3-devkitc-1/WiFiManager/` 目录下，如果想看原始 HTML 生成逻辑可以看那里的源码。你是想改配网页面的哪部分？


<ide_opened_file>The user opened the file d:\PlatformIO1\Projects\Healthv2.0\src\wifi_manager.cpp in the IDE. This may or may not be related to the current task.</ide_opened_file>

HTML是烧录在单片机里了吗


The user is asking whether the HTML for the WiFi configuration portal is actually flashed/burned into the microcontroller (ESP32). This is a good question - they want to understand how the WiFiManager library works.

The answer is: Yes, the HTML is essentially "baked in" to the WiFiManager library's source code (C++ strings), which gets compiled into the firmware binary and flashed to the ESP32. When a user connects to the ESP32's AP mode and opens the captive portal, the ESP32 serves these HTML pages directly from its flash memory.

Let me verify by checking the WiFiManager library source to show them exactly where the HTML strings are defined.


是的，HTML 页面代码**编译进了固件里**，烧录时一并写入 ESP32 的 Flash。WiFiManager 库不是靠外部文件，而是用 **C++ 字符串** 把 HTML 硬编码在源码中。

让我找到库里的具体位置：
