Soft WDT reset #8

Closed blazoncek closed 5 months ago

First off, thank you for a very versatile library. It makes handling ESP-NOW very easy.

Unfortunately I am seeing "Soft WDT reset" on my ESP8266 installations when sending packets while connected to WiFi network.

My initialisation looks like this:

  if (enableESPNow) {
    quickEspNow.onDataRcvd(espNowReceiveCB);
    bool espNowOK;
    if (apActive) {
      DEBUG_PRINTLN(F("ESP-NOW initing in AP mode."));
      #ifdef ESP32
      quickEspNow.setWiFiBandwidth(WIFI_IF_AP, WIFI_BW_HT20); // Only needed for ESP32 in case you need coexistence with ESP8266 in the same network
      #endif //ESP32
      espNowOK = quickEspNow.begin(apChannel, WIFI_IF_AP);  // Same channel must be used for both AP and ESP-NOW
    } else {
      DEBUG_PRINTLN(F("ESP-NOW initing in STA mode."));
      espNowOK = quickEspNow.begin(); // Use no parameters to start ESP-NOW on same channel as WiFi, in STA mode
    }
    statusESPNow = espNowOK ? ESP_NOW_STATE_ON : ESP_NOW_STATE_ERROR;
  }

And for sending packets:

typedef struct PartialEspNowPacket {
  uint8_t magic;
  uint8_t packet;
  uint8_t segs;
  uint8_t data[247];
} partial_packet_t;

...

  if (enableESPNow && useESPNowSync && statusESPNow == ESP_NOW_STATE_ON) {
    partial_packet_t buffer = {'W', 0, (uint8_t)s, {0}};
    // send global data
    DEBUG_PRINTLN(F("ESP-NOW sending first packet.")); 
    memcpy(buffer.data, udpOut, 41);
    auto err = quickEspNow.send(ESPNOW_BROADCAST_ADDRESS, reinterpret_cast<const uint8_t*>(&buffer), 41+3);
    if (!err) {
      // send segment data
      buffer.packet++;
      size_t packetSize = 0;
      int32_t err = 0;
      for (size_t i = 0; i < s; i++) {
        memcpy(buffer.data + packetSize, &udpOut[41+i*UDP_SEG_SIZE], UDP_SEG_SIZE);
        packetSize += UDP_SEG_SIZE;
        if (packetSize + UDP_SEG_SIZE < sizeof(buffer.data)/sizeof(uint8_t)) continue;
        DEBUG_PRINTF("ESP-NOW sending packet: %d (%d)\n", (int)buffer.packet, packetSize+3);
        err = quickEspNow.send(ESPNOW_BROADCAST_ADDRESS, reinterpret_cast<const uint8_t*>(&buffer), packetSize+3);
        buffer.packet++;
        packetSize = 0;
        if (err) break;
      }
      if (!err && packetSize > 0) {
        DEBUG_PRINTF("ESP-NOW sending last packet: %d (%d)\n", (int)buffer.packet, packetSize+3);
        err = quickEspNow.send(ESPNOW_BROADCAST_ADDRESS, reinterpret_cast<const uint8_t*>(&buffer), packetSize+3);
      }
      if (err) {
        DEBUG_PRINTLN(F("ESP-NOW sending packet failed."));
      }
    }
  }

The snippet above deals with oversized packets and works well on ESP32 (also tested on ESP32-C3, but for some reason QuickEspNow will not work at all on ESP32-S2 but that is for another issue). The code above finishes/completes without issue on ESP8266 but a few seconds after it is executed soft watchdog triggers a reset.

I managed to dump crash log using exception decoder and it is attached below. Apparently espnowTxHandle() stalls somewhere.

Do you have any idea what might be wrong?

--------------- CUT HERE FOR EXCEPTION DECODER ---------------
gmag11 commented 5 months ago

Hi. Initialization seems to be ok. But it seems that you make something with sent buffer just after send. Normally you should wait until library calls the sent callback. Have a look to advancedespenow example. Here, dataSent is a callback that runs when last packet has been sent and confirmed (or timed out).

The result of QuickESPNOW.send does not mean actually that message has been sent but shows if call is ok.

I see a reference to HardwareSerial::write at the end your log. Normally this means that error is produced during a Serial.print statement. I think it is not your case, but be careful to not overload serial buffers. This happens to me when I do verbose debug without filtering. Keep that in mind.

I think it would be useful for simple applications to have a synchronous mode so that send function only returns when espnow internal library calls sent callback. I'll think about it.

blazoncek commented 5 months ago

Hi. Thanks for the explanation. I did check advancedespnow several times when writing above code. I didn't think I needed actual callback on dataSent as I do not need any confirmation or other use for that.

Yes, we need to send (up to) 6 packets (about 1400 bytes) that comprise a full payload. Everything needs to work asynchronously without delaying main loop as it is used for realtime data (calculating LED effects). I have assumed that QuickESPNOW handles such approach (and it seems it does well on ESP32).

BTW HardwareSerial might be a debugging trace.

gmag11 commented 5 months ago

QuickESPNOW works with a queue to send messages. It has a buffer for 3 messages. There is a process that consumes the queue and actually send messages through esp-now, but only if last packet is confirmed.

So, you can send up to 3 messages in a row without waiting, but if queue is full and you try to send a new message, then the older in the queue is discarded.

You can increase queue depth by tuning ESPNOW_QUEUE_SIZE into header files. It will consume about 300 bytes for every message.

I'm doing some changes in the library to allow synchronous sending, but, if your timing is critical, I would recommend to control it by yourself so that you may use full queue. With synchronous mode only one packet can be stored.

blazoncek commented 5 months ago

Hi. I was able to (logically) trace where the problem is (it is twofold).

1) calling delay() function from within ISR should not happen (assuming espnowTxTask_cb is called from OS timer interrupt) 2) sending a few messages in quick succession may enter a loop that takes too much time for WDT

Let's say you quickEspNow.send() 4 messages (overflowing queue). First call to espnowTxHandle() will set readyToSend to false until sending of a single packet completes (in tx_cb) but there are still 2 meesages in queue so it will enter while (!readyToSend) delay(1); loop which may be enough to trigger WDT as delay() is not permitted in ISR.

What I would do is break out of espnowTxHandle() instead of entering while (!readyToSend) loop and wait for next timer invocation of espnowTxTask_cb().

I still need to test my theory and may do a PR if it is correct and you think it worthwhile.

blazoncek commented 5 months ago

Update: Seems to work well. No more WDT reset.

blazoncek commented 5 months ago

One more thing.

When the ring buffer is full I would expect (and would be the correct way) for quickEspNow.send() to fail and not discard last message. That way it would be easy to handle such errors in the application.
