ESP8266 + Blynk.virtualWrite = Crash "cause:4, boot mode:(3,6)"

ilya7zz · May 16, 2021, 9:49pm

When the timer is quickly changed by pressing the “+” or “-” button (or with inactivity for 30 minutes or more), it reboots with an error in Serial.
For more than a week I have been looking for a reason, I failed.
I ask for help to figure it out.
ESP8266 and WiFi.

Why are you doing this in your void loop, instead of using a timer?..

Don’t you think that using the Time library would be better than all of that code in your strangely named timerRUN function?

What does the Exception Decoder tell you about your Exception 9 error?

Pete.

ilya7zz · May 17, 2021, 2:54pm

Timer lags behind (skips seconds when the processor is loaded) and eats up ~ 500 bytes more memory.

I don’t know how to get a detailed answer for EspExceptionDecoder
Now I get short error messages:

During the experiments, a detailed error rarely appeared, which may not be relevant now:

Exception 9: LoadStoreAlignmentCause: Load or store to an unaligned address
PC: 0x4020dc11: tcp_kill_state at core/tcp.c line 1780
EXCVADDR: 0x3ffe86ca

PeteKnight · May 17, 2021, 3:12pm

If the timer is lagging then either your timed functions are taking too long to execute, or the void loop is being prevented from executing timer.run at the required frequency.
Is your memory usage that critical? If so then you have serious problems with your code.

As I said before, all of your time/date calculations once every second are very clunky and inefficient, and I guess this is what is “loading your processor”. Bear in mind that the ESP is a single core, single threaded processor and can only perform one task at a time.

Install the exception decoder in the IDE, copy the error where it says “Cut here”, paste it into the decoder and decode.

Pete.

ilya7zz · May 17, 2021, 5:21pm

Exception decoder is installed. The decoder does not see such short messages:

Timer is irrelevant to the question. Many tasks work stably. I cut out 90% of the code to show where the error I could not deal with. The Timer does not suit me, because some measurement procedures cause a delay and it should not interfere with the operation of the operating time counter, timer, etc. Despite the short-term CPU load with complex tasks or delay ();

Any change to the above code, even the removal of non-executable lines, removes the error. I am not able to understand this. For example, the variable flag = 0, but if you specify it again, before the condition, the error disappears. Also happens when commenting on any line Blynk.virtualWrite - the error disappears. I do not understand where the conflict is. I do not see him.

PS: Sorry if I am writing it incomprehensibly. As you can see, I am using google translator

ilya7zz · May 17, 2021, 5:26pm

The errors I see now are short.

PeteKnight · May 17, 2021, 5:41pm

This is the text that you should be pasting into the exception decoder…

--------------- CUT HERE FOR EXCEPTION DECODER ---------------

Unfortunately, Blynk is very fussy about timing, and as a result doesn’t like cluttered void loops.
So, maybe this project isn’t suitable for use with Blynk (or vice-versa, depending on your perspective).

That’s not an error, it’s the boot information from your NodeMCU.

Pete.

ilya7zz · May 17, 2021, 5:48pm

He doesn’t appear anymore. This was one time when I was declaring a String inside the code, and not beforehand.

If after several fastenings of the “+” button the board restarts, this is an error. I showed an error that is displayed on reboot.
I customize (create) a project for use with Blink. Therefore, I asked for help to find where the error was.

ilya7zz · May 17, 2021, 6:19pm

Fixed in the example on Timer, so as not to distract from the essence of the question

Problem: when you press the “+” or “-” button in the application, it reboots with the output to the Serial:

If I remove the comment “// flag = 0;” or comment out almost any line that contains Blynk. - the error disappears.

Ah yes, there’s a WDT reset in there.
Much easier to see when you don’t post a screenshot

How long does it take for Task1() to complete, and how long for BLYNK_WRITE(vPIN_TIMER_SET) to complete?

Pete.

Why do you keep posting screenshots???

Would you like me to go through your serial output and work-out the answer, or are you going to do that?

Pete.

Show changes with arrows for clarity. Sorry, I won’t do it anymore.

I didn’t get it. Didn’t you need to count the μs?

I just wanted to know how long each function took to execute.
I could either study your code and work-out what you’ve done, then compare that to the serial output and calculate the answer, or you could just tell me the answer.
Obviously too much trouble, so I’ll step back and let others share their thoughts on the cause.

Pete.

ilya7zz · May 17, 2021, 8:42pm

Different time was spent on performing the functions, so I counted and wrote it in the output for clarity.

Thanks, I’ll wait. I spent almost 2 weeks trying to find the problem on my own and couldn’t.

AlexArGC · May 24, 2021, 6:19am

С платой точно все ОК, проверяли?
SyncAll() лучше заменить только на нужные пины Blynk.syncVirtual(vPin);…

ilya7zz · May 24, 2021, 8:37am

Плата 100 живая, у меня их несколько. На конкретно этой крутится уже довольно жирный код с аптаймом более недели (pinger, опросы датчиков воздуха, PZEM, много алгоритмов отслеживания и исполнения…). Ошибка только в приведённом оставшемся куске после урезания, для поиска. Эта ошибка с перезагрузкой пропадает, даже если раскомментировать строчку “// flag = 0; // Removes the error why???” - не смотря на то, что ранее flag уже присвоен “0”. Или убрать условие которое не выполняется.

Спасибо за совет, не знал Я использую SyncAll() также для синхронизации Digital пинов.
Для теста убрал из кода:

BLYNK_CONNECTED()
{
  Blynk.syncAll();
//  Blynk.syncVirtual(vPin);
}

По-прежнему перезагружается, как только активно жму кнопку “+” или “-”.

Где вы прочитали, что Blynk.SyncAll() синхронизирует DigitalPIN’s? Попробуйте всетаки уйти от Blynk.SyncAll(). У меня случалось так, что некоторые vPIN’s просто пропускались этой функцией, особенно когда их 3 десятка используется. Пришлось прописать принудительно каждый vPIN.
На сколько я понял у вас локальный сервер?
Не надо использовать SimpleTimer в Blynk уже есть таймер BlynkTimer.
При частом нажатии +/- ошибка вызывается функцией BLYNK_WRITE(), такое было у виджета Slider, когда слишком больше количество значений вылетало в порт. Там даже добавили настройку “Отправлять последнее значение”. ESP8266 довольно слаба для такой “активности”.
Предполагаю что придется Вам на ESP32 перелезть… Протестировал ваш код на своей ESP32, не получилось +/- в Reset увести её…

Не прочитал, а увидел на практике =) И как по-другому их синхронизировать, после перезагрузки ESP – мне неизвестно. Например нажата кнопка освещения в приложении и кратковременно отключат электричество. А переписывать на Virtual pins усложнит (утяжелит) код и время срабатывания.

Нет, пока внешний: 139.59.206.133 = Blynk-cloud.com
От DNS решил отказаться для быстродействия.

Я использую свой собственный. Ранее для примера написал ‘SimpleTimer’, чтобы уменьшить встречные вопросы Мой таймер (был ранее в примерах) не пропускает и не “уходит” при работе. Это очень важно для обратного отсчёта и статистики работы.

Я предполагал, что происходит некое “наложение” выполнения этих функций. Как-то можно выкрутиться?

Неужели нельзя как-то пофиксить? Это же больше ошибка кода, чем процессора?! Я своим кодом очень слабо нагружаю ESP8266 и перелазить на ESP32 это финансово неприятно. Порой и 3х нажатий на “+” достаточно для перезагрузки.

Также мне совершенно непонятно, каким образом влияет повторное объявление:
// flag = 0; // Removes the error why???
на работу условия?
Само условие if (flag == 1) не выполняется, но влияет на появление этой ошибки. Очень много строк, кроме BLYNK_WRITE(), убирают появление ошибки, но понять я не в силах, т.к. только учусь.
