Let me build and upload. The re-enabled frame debug will show us all 40 frames with full data bytes, which will help us understand what the radar is actually sending now (vs before when it worked).


Bash

cd "d:/PlatformIO1/Projects/Healthv2.0" && "D:/PlatformIO/penv/Scripts/platformio.exe" run --target upload 2>&1 | tail -4

Upload with full frame debug

========================= [SUCCESS] Took 55.24 seconds =========================


Uploaded. Now the user should open the serial monitor and show me the [R1] through [R40] lines. These will show all the frames and their data bytes.


上传好了。开串口，把前 40 行 `[R1]` ~ `[R40]` 贴出来，就能看到雷达现在的完整输出模式了。

[雷达] 心率 raw: cmd=02 len=1 d0=85现在能观测了


The data is working now!

- Heart rate: cmd=02, len=1, d0=85 → 85 bpm ✓
- Breathing: cmd=02, len=1, d0=14/18 → 14-18 breaths/min ✓
- Presence: 1, Resident: 1 ✓
- WiFi: 1, MQTT connected ✓

The radar is now working properly with the query commands.

Now let me:
1. Remove the debug prints (they're filling up serial output)
2. Keep the data extraction as-is

Let me clean up the code by removing the frame debug and the raw data debug.


数据完美！心率 85、呼吸 18，和之前一样。现在把调试关掉，正式上线：

刚才为啥那样


OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


The user is asking "刚才为啥那样" - why did the radar behave differently before (showing d0=1, no data for 70 seconds, etc.) vs now (working perfectly with HR=85, BR=18).

The reason: when I removed the query commands (queryInitStatus, queryDetectRange) and let the radar "auto-start", it took 70+ seconds to begin reporting, and even then only sent status bytes (d0=1) instead of real data. The radar apparently needs the active query to enter full reporting mode.

When I put the query commands BACK, the radar responds immediately and starts sending real data (cmd=0x02 with actual values like 85 and 18).

So the key difference is: **主动查询命令**. Without them, the radar stays in a minimal/passive mode. With them, it switches to full active reporting.


之前把查询命令删了，让雷达自己慢慢启动——它等 70 秒才出数据，而且发的还是状态码（`d0=1`），不是真实值。加回 `queryInitStatus()` + `queryDetectRange()` 后雷达立刻进工作模式。

简单说：**R60ABD1 必须主动问一句才会正经干活。**

关串口上传正式版。


现在有问题，无论是我怎么弄心率一直时85，我的真实心率变了他也不改变。呼吸也容易卡到4，


The user is saying:
1. Heart rate is stuck at 85 regardless of real heart rate changes
2. Breathing sometimes gets stuck at 4

This suggests the data extraction might be filtering correctly but the radar itself isn't updating the values. Or there might be a caching issue in the extraction code.

Let me think about this:
- The heart rate value 85 is from `cmd=02, len=1, d0=85`. If the radar keeps sending 85, maybe it's not locking onto the person properly.
- The breathing value 4 is suspiciously low for an adult (normal is 12-20).

Possible issues:
1. The radar might be sending multiple frames for heart rate (cmd=0x00 status frames AND cmd=0x02 data frames), and my code might be reading a mix of both
2. The `cmd=0x00` status frame might have data[0] that's being read as the heart rate in some cases
3. The filter `v != 0x80 && v != 0x00 && v >= 40` might be letting through stale values

Wait, looking at the raw data from earlier:
- Heart rate: cmd=02, len=1, d0=85 → valid, accepted
- Heart rate: cmd=00, len=1, d0=1 → status byte, rejected by `v >= 40` check

So the cmd=0x00 frames (d0=1) are correctly rejected. The cmd=0x02 frames (d0=85) are accepted. But if the radar keeps sending 85 in cmd=0x02, that's a radar issue, not code.

Actually, let me reconsider. The R60ABD1 might need the person to be relatively still for 15-30 seconds before it can get a heart rate lock. If the person moves, the radar might lose lock and keep reporting the last known value.

Also, breathing at 4 is definitely wrong. Normal adult breathing is 12-20. 4 would be near-death. The radar might be incorrectly detecting or losing lock.

Let me add the raw data debug back temporarily to see what values are actually coming through. Maybe the radar is sending different commands that I'm not handling properly.

Actually, let me think about this differently. The user said "无论我怎么弄心率一直是85" - heart rate is ALWAYS 85, never changes. This could mean:
1. The radar really is stuck at 85
2. Or my code is reading from a cached value

Looking at the code:
```cpp
if (v != 0x80 && v != 0x00 && v >= 40) {
    _data.heartRate = v;
```

This only updates `_data.heartRate` when the value passes the filter. If the radar sends:
- cmd=02, d0=85 → accepted, heartRate=85
- cmd=02, d0=80 → rejected (0x80=128)
- cmd=02, d0=0 → rejected (0x00)
- cmd=00, d0=1 → rejected (1 < 40)
- Then back to cmd=02, d0=85 → accepted again

The heart rate would stay at 85 because the intermediate values are all rejected. But actually, this is the correct behavior - we don't want to update with invalid values.

Since the user says it never changes, maybe the radar is sending a mix of frames and the actual new value is in a different cmd type that I'm not reading.

OR maybe the issue is simpler - maybe the `_data` struct is being read at the wrong time, or there's a race condition with the RadarTask on Core 0.

Let me add back temporary raw data printing (every 3 seconds) to see ALL the heart rate frames and values. This will tell us what's actually happening.

Actually, the user might also just need to wait for the radar to re-lock. R60ABD1 takes about 30 seconds of stillness to lock heart rate.


数据可能卡在 `_data` 没更新。加回临时打印看真实流：

The user says "start 3" - probably means they uploaded and want me to look at the first 3 seconds of data, or they're testing something. Let me wait for them to share the serial output.

Actually, maybe they're saying "the data started" and there are 3 items to check. Let me wait for the serial output.


上传完了吧？开串口把 `[R] HR` 和 `[R] BR` 那几行贴出来。


我不在了走了以后，他心率呼吸一直是71，4，有没有人离开后测量的逻辑


The user wants logic for when nobody is present:
1. After the person leaves, heart rate and breathing should reset to 0 (not keep showing old values 71 and 4)
2. Vital signs should be invalidated when nobody is detected

Currently, the code keeps the last known heart rate and breathing regardless of presence. I need to:
1. When presence changes from 1 to 0, clear heart rate and breathing values
2. Set vitalValid = false when nobody is present

Let me add this to the radar data extraction or to the main loop.

I need to add logic: when presence frame says "nobody" (0), clear the vital signs data. Let me add this to the presence extraction.

The simplest approach: when cmd=0x00 or cmd=0x03 says presence=0, clear heartRate/breathRate and set vitalValid=false.


在心率和呼吸之前加 `_extractPresence` 里：当无人帧来了，清零体征。

Also remove the debug print from breathing and heart rate extraction since we're going to production now. Actually, let me keep it for now to confirm the data flow. Actually, the user already confirmed the radar works - let me remove them.

Actually, let me just compile and upload first with the "clear on nobody" fix. I'll remove the debug prints in a final cleanup.

我回来后，他就不变了


OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


The user is saying that after they come back, the heart rate and breathing don't change (stay at 0 since the "no presence" code cleared them). The issue is that when nobody is present, `cmd=0x00` with v=0 clears the vitals. But when the person returns, `cmd=0x00` with v=1 sets presence=true, but the heart rate and breathing might take a while to lock on again.

Actually, the problem might be worse: the clearance code fires on EVERY cmd=0x00 frame with v=0. When the radar briefly loses presence (which happens often with millimeter wave), it immediately zeros out heart rate and breathing. Then when presence returns, heart rate and breathing need to be re-acquired from scratch.

Also, when the person leaves and comes back:
1. Person leaves → cmd=0x00 v=0 → presence=false, heartRate=0, breathRate=0
2. Person returns → cmd=0x00 v=1 → presence=true, but heartRate and breathRate are still 0
3. Radar needs time to re-lock on heart rate (could be 15-30 seconds)
4. During this time, heart rate stays 0 even though the person is there

The user says "回来后就不变了" - after coming back, the values don't change. This is likely because:
1. The radar re-detects presence quickly (cmd=0x00 v=1)
2. But heart rate lock takes 15-30 seconds
3. In the meantime, `cmd=0x02` frames for heart rate might be sending d0=1 (status, not value) which gets filtered out
4. The actual cmd=0x02 d0=85 frames take time to come back

The fix: DON'T immediately clear vitals when presence drops. Instead, use a timeout - only clear vitals if no heart rate update has been received for some time (e.g., 30 seconds). Or better, just don't clear at all and let the `vitalValid` flag indicate whether the data is fresh.

Actually, the simplest fix: when presence is false, just mark `vitalValid = false` but DON'T zero out the values. The telemetry will show `体征:0` indicating invalid, but the last known values are preserved. When the person returns and the radar locks on again, the values update naturally.

Even better: just remove the clearance entirely. The `vitalValid` flag already tells whether the data is valid. If nobody is present and the radar stops sending valid heart rate, `vitalValid` naturally becomes false. Let me just remove the zeroing.

Leaving...

========================= [SUCCESS] Took 49.00 seconds =========================


Done. Summary of the fix:

1. When presence goes to 0 (nobody), only set `vitalValid = false`, don't zero out the values
2. When the person returns, heart rate and breathing resume from the last locked values
3. The radar will re-lock within 15-30 seconds and update with new values

Also removed all debug prints - the code is now production-ready.


上传好了。现在的逻辑：

```
人离开 → 体征标记为"无效"（体征:0），但旧值保留不丢
人回来 → 雷达 15-30 秒重新锁心跳 → 自动更新为新的心率呼吸
```

不再清空了，人走人回数据连贯。

The user says their heart rate can't be detected again. Let me look at the current radar_manager.cpp to check if there's an issue with the heart rate extraction. The last time this happened, the query commands needed to be re-added. But they should still be there.

The query commands are there. And presence detection works (存在:1). The heart rate issue - let me check the extraction code again.

Wait, the user said "现在我的心率又测不到了" - their heart rate can't be detected AGAIN. This is the same issue as before. Let me look at the extraction code for heart rate. Maybe there's a problem with how the heart rate extraction filters the values.

Let me check the filter: `if (v != 0x80 && v != 0x00 && v >= 40)` - this requires the value to be >= 40. If the radar is sending heart rate values below 40 (like during re-locking), they'd be filtered out.

Also, maybe the issue is that the radar needs more time to stabilize after the query commands. Let me add back temporary raw data debug for heart rate.


代码没变，查询命令也在。可能雷达需要时间重新锁。加回 3 秒打印看看：

OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


The user should now open the serial monitor and look for [HR] lines. The debug will show what the radar is actually sending for heart rate (cmd and value).

Actually, having this much back-and-forth with the radar data is inefficient. Let me think about the root cause and fix it once and for all.

The pattern I've observed:
1. On first boot with query commands: radar works, heart rate 85, breathing 18
2. After power cycle without query commands: radar slow to start, sends status bytes (1) instead of data
3. After person leaves: presence goes to 0, vitals invalid
4. After person returns: heart rate might not re-lock, or sends different values

The fundamental issue might be that the radar has multiple operating modes and the query commands don't reliably put it in vital signs mode.

But actually, the data was working fine before (HR=85, BR=18). The user says "又测不到了" (can't detect AGAIN). This might just be a transient issue with the radar repositioning or needing to re-lock.

Let me wait for the user to show the [HR] output.


开串口，站到雷达前面静止 30 秒，看 `[HR]` 那行是什么。

Now I can see the issue clearly:

1. Heart rate: `cmd=00 v=1` → status byte, filtered out (1 < 40). `cmd=02 v=0` → 0, filtered out.
2. Breathing: showing 4, coming from... which cmd? There's no debug for breathing now.

The heart rate is NOT being detected. The radar sends:
- cmd=0x00, v=1 → status "heart rate monitoring active" but no data
- cmd=0x02, v=0 → actual value is 0 (no lock)

This is the radar's initialization/re-locking phase. The query commands wake up the radar, but the radar still needs time to lock onto the person's heart rate.

Previously when the radar DID work (showing 85), the cmd=0x02 was sending 85. Now it's sending 0, which means the radar hasn't locked.

Possible reasons:
1. The person isn't still enough (R60ABD1 needs ~30 seconds of stillness for heart rate lock)
2. The radar needs the commands sent in a different order or with different timing
3. The radar might need to be re-initialized with a different sequence

Looking at the breathing: shows 4. That's suspiciously low but it IS being updated (presence=1, breathing=4). This means some data is coming through.

Let me add more time before query commands, or add more query commands. Also, the query commands might need to be sent with a longer delay between them.

Let me also add the breathing debug to see what cmd is being used.

Actually, let me look at the successful session data more carefully:
- Before (working): cmd=02, v=85 for HR, cmd=02, v=18 for BR
- Now: cmd=00, v=1 (status), cmd=02, v=0 (no HR)

The query commands might be interrupting the radar's normal auto-reporting flow. Let me try removing queryInitStatus and queryDetectRange again, but this time wait longer.

Actually, wait - the previous successful session was WITHOUT query commands but with a LONG wait (70 seconds). The query commands version worked once too. Maybe the issue is just time - the radar needs 60+ seconds to lock heart rate.

Let me tell the user to wait 2 minutes without moving.


问题找到了——`cmd=02 v=0`，心率锁还没建立（需要静止 30-60 秒）。雷达刚上电还在初始化。

呼吸也在低值 `4`。加呼吸调试确认一下：

而且很慢


The user says it's very slow. The radar takes too long to start reporting data. Let me fix this: increase the delay before query commands, and maybe change the query sequence to make it faster.

Also, looking at the data:
- Takes ~60 seconds just to get first data
- Heart rate: cmd=02 v=0 (not locked yet)
- Breathing: shows 4 (locked but low)

The radar needs more initialization time, but also more time to lock vitals. Let me:
1. Increase the initial delay to 2 seconds before query commands
2. Or try a different query sequence

Actually, the "slow" might refer to the heart rate taking too long to appear. Let me think about what's different from the successful session...

In the successful session (yesterday), the radar showed HR=85 and BR=18 almost immediately after presence was detected. The key difference: yesterday the radar was already warmed up (had been running for a while from previous boots). Today it's cold-starting.

Let me just tell the user to be patient and wait 2 minutes, or increase the delay before queries.


雷达冷启动慢。延长时间保证充分初始化：


    // 主动查询让雷达快速进入工作模式
    delay(500);
    queryInitStatus();
    delay(100);
    queryDetectRange();

    Serial.println(F("[雷达] 雷达模块初始化完成, 已发送查询命令, 等待数据..."));
    return true;

    // R60ABD1 冷启动需要充足时间，等雷达自检完再查询
    delay(3000);
    queryInitStatus();
    delay(500);
    queryDetectRange();
    delay(500);
    // 再查一次，确保雷达响应
    queryInitStatus();

    Serial.println(F("[雷达] 雷达初始化完成, 等待数据 (冷启动约需30-60秒)..."));
    return true;


    // 主动查询让雷达快速进入工作模式
    delay(500);
    queryInitStatus();
    delay(100);
    queryDetectRange();

    Serial.println(F("[雷达] 雷达模块初始化完成, 已发送查询命令, 等待数据..."));
    return true;

    // R60ABD1 冷启动需要充足时间，等雷达自检完再查询
    delay(3000);
    queryInitStatus();
    delay(500);
    queryDetectRange();
    delay(500);
    // 再查一次，确保雷达响应
    queryInitStatus();

    Serial.println(F("[雷达] 雷达初始化完成, 等待数据 (冷启动约需30-60秒)..."));
    return true;

-    // 主动查询让雷达快速进入工作模式

+    // R60ABD1 冷启动需要充足时间，等雷达自检完再查询

+    // 再查一次，确保雷达响应

-    Serial.println(F("[雷达] 雷达模块初始化完成, 已发送查询命令, 等待数据..."));

+    Serial.println(F("[雷达] 雷达初始化完成, 等待数据 (冷启动约需30-60秒)..."));


Build and upload. The changes:
1. Delay 3 seconds before any query (vs 500ms)
2. Send queryInitStatus twice with longer gaps
3. Total init time increased

The user should also wait patiently after upload - the radar needs 30-60 seconds after the first data frame to lock onto heart rate.

─────────────────这是串口数据，心率还是0，呼吸为啥一直是4，上来也是。


Looking at the data:

1. Heart rate: consistently `cmd=00 v=1` - status byte only, never gets actual data. The `cmd=02 v=0` from before is gone now, replaced by `cmd=00 v=1`.

2. Breathing: consistently `cmd=00 v=1` - status byte, shows as 4 in telemetry? Wait, the telemetry shows "呼吸:4" but the debug shows `[BR] cmd=00 v=1`. That means `v=1` passes the filter `v != 0x80 && v != 0x00 && v <= 40` → true (1 != 0x80, 1 != 0x00, 1 <= 40). So breathRate = 1.

But wait, telemetry shows "呼吸:4" sometimes and "呼吸:1" other times. The breathing value 4 vs 1 - there must be another frame type coming in that I'm not seeing because the debug only prints every 3 seconds.

Actually, looking more carefully:
- `[BR] cmd=00 v=1` → this sets breathRate to 1
- But the telemetry shows 呼吸:4 in some readings

This means there's another breathing frame (maybe cmd=02) coming through that I'm missing because the debug is rate-limited to every 3 seconds.

The fundamental issue: the radar is NOT sending `cmd=02` frames with real values (85, 18) like it did yesterday. Instead, it's only sending `cmd=00` status frames (v=1).

This is strange. Yesterday, the same code and same radar worked fine - sending `cmd=02 v=85` for HR and `cmd=02 v=18` for BR. Today, with the same board, it's only sending `cmd=00 v=1` status frames.

Possible explanations:
1. The radar firmware might have different modes depending on environment
2. The person might not be in the optimal position
3. The radar might need different init commands

Let me try a different approach: send specific enable commands for heart rate and breathing reporting. Looking at the protocol, cmd=0x03 is SET command. I can try:
- Send 0x85 cmd=0x03 with data to enable heart rate
- Send 0x81 cmd=0x03 with data to enable breathing

Or maybe I should try query commands for each subsystem:
- queryHeartRate, queryBreathing

The sendCommand function already exists. Let me add specific queries for heart rate and breathing.

Actually wait - looking at the data more carefully, the radar DOES respond to queryInitStatus (it sends back 0x05 cmd=0x01 with data[0] field). And it sends product info (0x02 frames showing "R60A"). But the presence, breathing, heart rate frames are all cmd=0x00 (status only) instead of cmd=0x02 (actual data).

Maybe the radar needs to be told to switch to "full reporting mode". Let me try sending CMD_SET (0x03) to enable full data reporting for presence, breathing, and heart rate.

Or maybe I should try a different approach entirely: send cmd=0x01 (QUERY) to each subsystem individually, which might trigger them to start reporting full data.


心率从来没出 `cmd=02`——全是 `cmd=00 v=1` 状态码，没收到真实数据。之前是发了查询才出 `cmd=02 v=85`。给心率和呼吸单独发查询命令：

Build and upload. The new init sequence queries ALL subsystems (presence, breathing, heart rate, sleep) individually, which should trigger the radar to respond with cmd=0x02 full data frames.


Bash

cd "d:/PlatformIO1/Projects/Healthv2.0" && "D:/PlatformIO/penv/Scripts/platformio.exe" run --target upload 2>&1 | tail -4

Upload with all subsystem queries


Leaving...
Hard resetting via RTS pin...
========================= [SUCCESS] Took 48.74 seconds =========================


OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


Now the init sequence queries each subsystem individually. Hopefully the radar will respond with cmd=0x02 data frames for heart rate and breathing.

The user should upload, wait, and show the [HR] and [BR] lines.


上传好了。开串口，站到雷达前面静止。看 `[HR]` 和 `[BR]` 里有没有出现 `cmd=02`。

The radar is working now! Heart rate 83-90 bpm, breathing 11 - both showing real values with cmd=02. The key was querying ALL subsystems individually.

Now let me:
1. Remove debug prints
2. Build the clean production version
3. Upload

The WiFi shows 0 (disconnected) but that's a separate issue - probably just needs MQTT reconnect.

Also, the radar works on 5V now instead of 3.3V. Good.


数据完美！心率 83-90，呼吸 11。5V 供电 + 全子系统查询 = 正常工作。

去掉调试，发布正式版：

怎么现在心率又一直在91，呼吸19，我去用手干扰还是这样


The user says heart rate is stuck at 91 and breathing at 19, even when they use their hand to interfere. The radar values are not changing in response to real changes.

The issue is likely that the radar needs time to lock onto the person, and once locked, it reports an average/stable value. R60ABD1 is designed for sleep monitoring - it tracks a stationary person's vitals over time. It's not meant to respond instantly to rapid changes.

Also, putting a hand in front of the radar would not change the heart rate reading - the radar is tracking the stationary person, not the hand. The 60GHz radar penetrates through limbs and tracks the torso.

This is actually expected behavior for a sleep/respiratory monitoring radar:
1. It takes 30-60 seconds to lock onto a person's heart rate
2. Once locked, it reports a stable/averaged value
3. Brief interruptions don't change the value quickly
4. It's designed for continuous monitoring of a stationary person, not rapid response

Let me explain this to the user. The values 91 and 19 are reasonable and likely correct for their resting state.


正常——R60ABD1 就是这样的，它是睡眠呼吸雷达，不是医疗级实时心率计：

```
雷达锁人后 → 输出一个时间窗内的平均值
不是每秒更新，是十几秒平滑一次
```

你用手干扰不改变你身体的真实心率——91/19 就是你安静坐着的数据。正常成人静息心率 60-100、呼吸 12-20，你的 91/19 在正常范围。

想让心率变，站起来跳几下，然后坐下静止 30 秒再看——数值会变。

The data shows heart rate fixed at 91 and breathing fixed at 19, never changing. Even presence is flickering between 0 and 1. This suggests the data is stale/cached and not actually updating.

The issue might be in the heartbeat extraction code. When the radar sends `cmd=02 v=91`, the code updates heartRate to 91. But if the radar stops sending new values, the old value persists.

Wait - the presence flickers (0,1,0,1) which means the radar IS sending data. But heart rate and breathing stay at exactly 91 and 19. These values appeared at 15 seconds and never changed for 60+ seconds.

Looking at the raw data from the previous session:
- HR cmd=02 v=90 → that was the last reading
- Then it stayed at 90

And now:
- HR=91, BR=19 → unchanged for 60+ seconds

The radar might be sending the SAME values repeatedly, or it might have stopped sending cmd=02 frames altogether after the first few readings.

Actually, the most likely cause: the `_extractBreathing` and `_extractHeartRate` functions update `_data.breathRate` and `_data.heartRate` only when valid values come in. If the radar stops sending valid cmd=02 frames, the last values stick.

But WHY would the radar stop sending? The presence data keeps updating (flickering 0/1), which means the radar IS communicating.

Let me think... Maybe the query commands cause the radar to respond once, then stop auto-reporting. The radar might need to be queried continuously, not just once at startup.

OR, maybe the issue is that the radar IS sending data but my filter is rejecting it. Let me add the raw debug back to see.

Actually, let me try a completely different approach: DON'T send any query commands, and also DON'T send the initial queries. Let the radar just auto-report. That's what worked the very first time (even though it was slow).


数据卡住了——91/19 从第 15 秒后就再也没变过。查询命令可能让雷达只回复一次就不发了。回到最原始方案——完全不查询，让雷达自己自然上报：

Wait, last time without query commands, the radar took 70 seconds to even start sending data, and then only sent cmd=0x00 status frames. Let me think about this differently.

The pattern seems to be:
1. Without query: 70s delay, then cmd=0x00 status frames only (no real data)
2. With query: 15s start, real cmd=0x02 data, but then data STOPS updating after first response

Maybe I need a hybrid approach: send one query to kickstart, then let auto-reporting take over. Or send queries periodically.

Actually, the first time (yesterday with the older board on 3.3V), without query commands, the radar DID eventually send cmd=0x02 frames with valid data after 70-80 seconds. And it CONTINUED to send them.

Today with the new board on 5V, without query commands, it took 60-70 seconds and only sent cmd=0x00 status frames.

The difference might be:
1. Power supply (3.3V vs 5V)
2. Board differences
3. Environmental factors

Let me try the no-query approach one more time, but wait longer. If it doesn't work, I'll try periodic querying.

Actually, let me just keep the no-query approach but add the debug prints back so we can see what the radar is doing.

看一下跌倒的逻辑


The user is asking about the fall detection logic. Let me look at the code and also check the `未识别控制字=0x01 长度=1 数据: 0F` from the earlier serial output. That 0x01 control word might be related to fall detection!

Wait, 0x01 is the heartbeat control word (CTRL_HEARTBEAT). The data 0x0F might be a heartbeat or status value.

But fall detection - where does it come from in the R60ABD1 protocol? Let me check:

1. The current code has a `_data.fall` field but I don't think it's ever set by any extraction function!
2. Let me verify this.

Looking at the radar protocol enum:
- 0x01: Heartbeat
- 0x02: Product info
- 0x80: Presence
- 0x81: Breathing
- 0x84: Sleep
- 0x85: Heart rate

There's no fall-specific control word in the current code. But R60ABD1 is supposed to have fall detection. Let me check if fall is embedded in one of the existing frames.

Actually, looking at the serial output, there's `未识别控制字=0x01 长度=1 数据: 0F`. The control word 0x01 is CTRL_HEARTBEAT. But cmd=0x00 doesn't match any expected command. The data 0x0F might have special meaning.

For R60ABD1, fall detection might be reported:
1. Through the presence frame (0x80) with a specific bit set
2. Through a separate control word not in our enum
3. Or through the heartbeat frame (0x01)

Let me check the presence extraction - is fall being extracted anywhere?

Actually, looking at the RadarRawData struct, `fall` is a field that's never assigned in any extraction function! That's why fall is always 0.

For R60ABD1, fall detection might be embedded in one of the data fields we're already receiving. Let me look at the presence cmd=0x05 full data frame - maybe byte 5 or 6 contains the fall flag.

Or maybe the unhandled 0x0F data from the heartbeat frame IS the fall signal.

Let me search for "fall" or "跌倒" in the radar code.


344:        // 跌倒检测: 可能在睡眠异常标志中
346:            _data.fall     = (frame.data[3] & 0x01) != 0;


So `_data.fall` is only set in `_extractSleep`:
```cpp
_data.fall = (frame.data[3] & 0x01) != 0;
```

But this requires `frame.data_length >= 3` and it's extracting from bit 0 of data[3]. This is a guess - we don't know if this is the correct location.

Looking at the serial output, there was `未识别控制字=0x01 长度=1 数据: 0F`. The 0x01 control word is in the enum as CTRL_HEARTBEAT, but it's not handled in the switch statement. Maybe 0x01 is actually a fall detection frame.

Let me look at what data frames the R60ABD1 can send for fall. Actually, R60ABD1 fall detection might:
1. Come through the 0x84 (sleep) frame as a flag bit
2. Come through a separate control word like 0x06 (fall detection)
3. Be embedded in the 0x80 presence frame with more data bytes

Since we don't have the datasheet, let me handle the 0x01 frame as a potential fall indicator. The data byte 0x0F (15 in decimal) could mean different things.

Let me also check the full _extractSleep code:


334	            _data.lastUpdate  = millis();
335	            _notifyUpdate();
336	        }
337	    }
338
339	    if (frame.data_length >= 3) {
340	        // data[0]: 入床/离床
341	        // data[1]: 睡眠状态
342	        // data[2]: 评分
343
344	        // 跌倒检测: 可能在睡眠异常标志中
345	        if (frame.data_length >= 4) {
346	            _data.fall     = (frame.data[3] & 0x01) != 0;
347	            _data.resident = (frame.data[3] & 0x02) != 0;
348	        }
349
350	        _data.lastUpdate = millis();
351	        _notifyUpdate();
352	    }
353	}
354
355	void RadarManager::_extractWorkStatus(const RadarFrame& frame) {
356	    if (frame.command == WS_INIT_COMPLETE && frame.data_length >= 1) {
357	        if (frame.data[0] == 0x0F) {
358	            _initialized = true;

            _data.lastUpdate  = millis();
            _notifyUpdate();
        }
    }

    if (frame.data_length >= 3) {
        // data[0]: 入床/离床
        // data[1]: 睡眠状态
        // data[2]: 评分

        // 跌倒检测: 可能在睡眠异常标志中
        if (frame.data_length >= 4) {
            _data.fall     = (frame.data[3] & 0x01) != 0;
            _data.resident = (frame.data[3] & 0x02) != 0;
        }

        _data.lastUpdate = millis();
        _notifyUpdate();
    }
}

void RadarManager::_extractWorkStatus(const RadarFrame& frame) {
    if (frame.command == WS_INIT_COMPLETE && frame.data_length >= 1) {
        if (frame.data[0] == 0x0F) {
            _initialized = true;


OK so the current fall detection logic is a GUESS - reading bit 0 of data[3] from the sleep (0x84) frame. This probably doesn't work.

Also, there's an unprocessed control word 0x01 (CTRL_HEARTBEAT) that sends data 0x0F. Let me add handling for the 0x01 heartbeat frame. Some R60ABD1 modules use the heartbeat frame to report special events like falls.

Also, looking at the protocol more carefully:
- 0x01: Heartbeat
- 0x02: Product info
- 0x05: Work status
- 0x07: Detect range
- 0x80: Presence
- 0x81: Breathing
- 0x84: Sleep
- 0x85: Heart rate

I should add handling for 0x01 (heartbeat) which might carry fall detection or other status info.

But without the datasheet, I'm guessing. Let me just:
1. Add the 0x01 frame handling to the process switch
2. Print its data so we can figure out the format
3. See if fall detection can be extracted from any known frames

Actually, let me check if R60ABD1 even supports fall detection. The user's module serial data shows it as "R60A" in the product info. The R60ABD1 is a breathing/sleep radar, NOT primarily a fall detection radar. Fall detection is mainly from the R60AFD1 model.

The user might have an R60ABD1 which focuses on presence, breathing, heart rate, and sleep - but NOT fall detection. Fall would be a feature of R60AFD1 (with the "F" for Fall).

Let me tell the user this.


`跌倒` 逻辑目前是瞎猜的——从睡眠帧里抽了一个 bit，大概率不对。R60**A**BD1 主打呼吸/心率/睡眠，跌倒检测是 R60**F**D1 的功能。

```cpp
// 当前代码在 _extractSleep() 里猜了一个位：
_data.fall = (frame.data[3] & 0x01) != 0;  // ← 纯猜测
```

要验证的话，我加个打印——故意摔倒（垫子上），看哪个帧哪个 bit 变了。但 ABD1 可能根本不输出跌倒数据。要不要试试？


触发跌倒了，恢复平稳，跌倒警报停了，但是数据一直还在，这里该怎么处理


The user has a module that DOES detect falls! That's good news. But the issue is: after recovering from the fall and standing back up, the alarm stops, but the `fall` data field stays as 1 (true).

The problem is in the extraction: once `_data.fall` is set to true, nothing ever sets it back to false. The radar might send a "fall cleared" signal, or it might just stop setting the fall bit.

I need to add logic to:
1. Reset `_data.fall` to false when the radar indicates the fall is over
2. Or use a timeout - if fall was last detected more than X seconds ago, clear it

Let me check how fall is being detected. The user said "触发跌倒了" and "恢复平稳，跌倒警报停了" - so the ALARM stopped (via checkLocalAlarms), but the DATA field stays true.

Looking at checkLocalAlarms:
```cpp
if (radar.fall && radar.radarValid && !g_localFallActive) {
    g_localFallActive = true;
    g_alarm.triggerLocal(ALARM_FALL);
} else if (!radar.fall && g_localFallActive) {
    g_localFallActive = false;
    g_alarm.clearLocal(ALARM_FALL);
}
```

If the alarm stopped, it means `radar.fall` went false at some point. But the user says "数据一直还在" - meaning the telemetry shows fall=1 even after recovery.

Wait, maybe `_data.fall` is set to true and then the radar stops sending the sleep frame that would update it. The fall bit might only be set ONCE and never cleared by subsequent frames.

Let me add an auto-clear timeout: if fall was detected more than X seconds ago, clear it. Or better, update the extraction to also check for "no fall" state.

Actually, let me first understand which frame type triggered the fall. Let me add debug to the fall-setting code.


跌倒检测命中了！但数据不清零——`_data.fall` 设成 true 后再也没有设回 false。加上自恢复：

Done. The fall logic now:
1. Fall triggered → `_data.fall = true`, record time
2. Radar stops sending fall bit → after 2 seconds, auto-clears to false
3. Worst case: after 5 seconds of no data at all, force clear

The user needs to test: simulate a fall, recover, and check if the fall flag clears within 2-5 seconds.


上传好了。新逻辑：

```
跌倒触发  → fall=1, 报警响
人站起来  → 雷达停发跌bit → 2秒后 fall=0
超时兜底  → 5秒没任何数据 → 强制清零
```

再试一次摔倒恢复，看跌倒标志会不会 2-5 秒内自己消失。

OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


The user has two concerns:

1. **After manually dismissing the alarm (GPIO13), the fall data flag should also reset** - Currently, pressing GPIO13 clears the alarm (clearAllLocal), but the `_data.fall` flag in the radar data structure stays true. The fall flag in the telemetry keeps showing 1.

2. **Sitting down sometimes falsely triggers fall detection** - The fall detection logic reads `frame.data[3] & 0x01` from the sleep frame, which might not be a true fall indicator. A sudden motion like sitting down could set this bit.

For issue 1: When the user presses GPIO13 to dismiss, the alarm clears but the data flag doesn't. I should add logic: when the local fall alarm is cleared, also reset the radar data's fall flag.

For issue 2: The current fall detection is just reading a bit from the sleep frame data[3] - we don't have the datasheet so it's a guess. Sitting down causes a sudden acceleration that the radar might interpret as a fall.

Let me fix both:

1. Make the alarm dismissal also clear the fall data flag
2. Add a note that fall detection is experimental/best-guess without the datasheet


两个问题：误判 + 手动解除后数据不归零。

    Serial.println(F("╚══════════════════════════════════════════╝"));


Let me find where the alarm dismiss callback is set up and add radar fall reset there.


372:    g_buttons.onAlarmDismiss([]() {
373:        g_alarm.clearAllLocal();
452:    RadarRawData radar = g_radar.getData();


Now I need to update the alarm dismiss callback to also reset the radar fall flag. And also fix the fall detection to be less prone to false positives.

For the alarm dismiss: when GPIO13 is pressed, also reset `_data.fall` in the radar. But the callback is a lambda that doesn't have access to `g_radar`. Let me change it.

For the false positive: sitting down causes a quick downward motion that the radar might flag. The current detection reads `data[3] & 0x01` from 0x84 (sleep) frame which is unreliable. Without the datasheet, we can't fix the false positive at the sensor level. But we can add a software filter: require the fall flag to persist for at least 1 second before triggering.

Let me fix both:
1. Dismiss callback clears radar fall too
2. Add 1-second debounce to fall detection


Edit

    g_buttons.onAlarmDismiss([]() {
        g_alarm.clearAllLocal();
    });

    g_buttons.onAlarmDismiss([]() {
        g_alarm.clearAllLocal();
        // 同时清除雷达跌倒标记，防止数据残留
        RadarRawData data = g_radar.getData();
        data.fall = false;
    });


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

    g_buttons.onAlarmDismiss([]() {
        g_alarm.clearAllLocal();
    });

    g_buttons.onAlarmDismiss([]() {
        g_alarm.clearAllLocal();
        // 同时清除雷达跌倒标记，防止数据残留
        RadarRawData data = g_radar.getData();
        data.fall = false;
    });

+        // 同时清除雷达跌倒标记，防止数据残留

+        RadarRawData data = g_radar.getData();


Wait, `getData()` returns a copy of RadarRawData, not a reference. So `data.fall = false` only modifies the local copy, not the actual `_data` member. Let me check getData.


426:RadarRawData RadarManager::getData() const {


`getData()` returns a copy (not reference), so modifying it won't help. I need to either:
1. Add a method to RadarManager to clear the fall flag
2. Or return by reference
3. Or access `_data` directly

Let me add a `clearFallFlag()` method.


`getData()` 返回的是副本。加个专门清除的方法：


426	RadarRawData RadarManager::getData() const {
427	    return _data;
428	}
429
430	// ============================================================

-        // 同时清除雷达跌倒标记，防止数据残留

-        RadarRawData data = g_radar.getData();


OLED GPIO 改为 14/15 (避开 PSRAM 冲突)


Now for the false positive issue: sitting down triggers fall detection. The problem is that `data[3] & 0x01` from the sleep frame is just a guess - it might be a "sudden motion" flag, not a real fall.

Without the datasheet, I can:
1. Add debounce: require the fall bit to stay true for >1 second before triggering alarm
2. Add a "velocity" check: also check the body movement value - a real fall usually has high body movement

Let me add a minimum duration filter.


现在加防误判——跌到位持续 1 秒以上才报警：


229
230	// ============================================================
231	// 本地报警检查 (离线可用)
232	// ============================================================
233
234	void checkLocalAlarms(const RadarRawData& radar) {
235	    uint32_t now = millis();
236
237	    // --- 跌倒检测 (本地紧急报警, 立即触发) ---
238	    if (radar.fall && radar.radarValid && !g_localFallActive) {
239	        g_localFallActive = true;
240	        g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
241	    } else if (!radar.fall && g_localFallActive) {
242	        g_localFallActive = false;
243	        g_alarm.clearLocal(AlarmManager::ALARM_FALL);

// ============================================================
// 本地报警检查 (离线可用)
// ============================================================

void checkLocalAlarms(const RadarRawData& radar) {
    uint32_t now = millis();

    // --- 跌倒检测 (本地紧急报警, 立即触发) ---
    if (radar.fall && radar.radarValid && !g_localFallActive) {
        g_localFallActive = true;
        g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
    } else if (!radar.fall && g_localFallActive) {
        g_localFallActive = false;
        g_alarm.clearLocal(AlarmManager::ALARM_FALL);


Let me add a debounce timer for fall detection. Instead of triggering immediately on fall=1, wait 1 second.


uint32_t g_presenceStartTime = 0;       // 首次检测到人的时刻
bool     g_vitalAlarmReady   = false;   // 心率呼吸报警就绪 (有人30秒后)

uint32_t g_presenceStartTime = 0;       // 首次检测到人的时刻
bool     g_vitalAlarmReady   = false;   // 心率呼吸报警就绪 (有人30秒后)
uint32_t g_fallStartTime     = 0;       // 跌倒开始时刻 (防误判)


uint32_t g_presenceStartTime = 0;       // 首次检测到人的时刻
bool     g_vitalAlarmReady   = false;   // 心率呼吸报警就绪 (有人30秒后)
uint32_t g_fallStartTime     = 0;       // 跌倒开始时刻 (防误判)

+uint32_t g_fallStartTime     = 0;       // 跌倒开始时刻 (防误判)


Now update the checkLocalAlarms fall section to use debounce:


    // --- 跌倒检测 (本地紧急报警, 立即触发) ---
    if (radar.fall && radar.radarValid && !g_localFallActive) {
        g_localFallActive = true;
        g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
    } else if (!radar.fall && g_localFallActive) {
        g_localFallActive = false;
        g_alarm.clearLocal(AlarmManager::ALARM_FALL);
    }

    // --- 跌倒检测 (持续1秒才触发，防坐下误判) ---
    if (radar.fall && radar.radarValid && !g_localFallActive) {
        if (g_fallStartTime == 0) g_fallStartTime = now;
        if (now - g_fallStartTime >= 1000) {  // 跌倒持续1秒才报警
            g_localFallActive = true;
            g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
        }
    } else if (!radar.fall && g_localFallActive) {
        g_localFallActive = false;
        g_fallStartTime = 0;
        g_alarm.clearLocal(AlarmManager::ALARM_FALL);
    }
    if (!radar.fall) g_fallStartTime = 0;  // 没有跌倒时重置计时


    // --- 跌倒检测 (本地紧急报警, 立即触发) ---
    if (radar.fall && radar.radarValid && !g_localFallActive) {
        g_localFallActive = true;
        g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
    } else if (!radar.fall && g_localFallActive) {
        g_localFallActive = false;
        g_alarm.clearLocal(AlarmManager::ALARM_FALL);
    }

    // --- 跌倒检测 (持续1秒才触发，防坐下误判) ---
    if (radar.fall && radar.radarValid && !g_localFallActive) {
        if (g_fallStartTime == 0) g_fallStartTime = now;
        if (now - g_fallStartTime >= 1000) {  // 跌倒持续1秒才报警
            g_localFallActive = true;
            g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
        }
    } else if (!radar.fall && g_localFallActive) {
        g_localFallActive = false;
        g_fallStartTime = 0;
        g_alarm.clearLocal(AlarmManager::ALARM_FALL);
    }
    if (!radar.fall) g_fallStartTime = 0;  // 没有跌倒时重置计时

void checkLocalAlarms(const RadarRawData& radar) {

-    // --- 跌倒检测 (本地紧急报警, 立即触发) ---

-        g_alarm.triggerLocal(AlarmManager::ALARM_FALL);
