Frequent reset after update to 2.1.7

[MudiStar]

Hello

I'm using your library in several esp 8266 and I'm pretty happy with it. So my code was running fine but since I updated to 2.1.7, I get the following reset sometimes 3 times per hour: Sometimes it takes longer.

ets Jan 8 2013,rst cause:4, boot mode:(3,6)

wdt reset load 0x4010f000, len 3460, room 16 tail 4 chksum 0xcc load 0x3fff20b8, len 40, room 4 tail 4 chksum 0xc9 csum 0xc9 v0007b6e0 ~ld

I also recognized, that if I don't have internet through the connected wifi (router restart after power outage) the esp keeps resetting with the same error.

Do you need more infomation to debug the problem?

Thanks

So it got a lot better since the esp core update to 3.1.0 Still one problem remains: reset of the esp if no internet is available.

0x4020ac08: AsyncTelegram2::checkConnection() at C:\Users\Arduino\libraries\AsyncTelegram2\src\AsyncTelegram2.cpp line 39

What I understand is, that the connection is checked in the frequency of the main loop and then the esp crashes this is what I also see in the serial monitor

1) all startet with begin():

bool AsyncTelegram2::begin()
{
    checkConnection();
    return getMe();
}

2) Connection is checked:

bool AsyncTelegram2::checkConnection()
{
    // Start connection with Telegramn server (if necessary)
    if (!telegramClient->connected())
    {
        m_lastmsg_timestamp = millis();
        log_info("Start handshaking...");

        if (!telegramClient->connect(TELEGRAM_HOST, TELEGRAM_PORT))
        {
            Serial.println("\n\nUnable to connect to Telegram server");
            reset();
        }

3) reset is called

bool AsyncTelegram2::reset(void)
{
    log_info("Restart Telegram connection\n");
    telegramClient->stop();
    m_lastmsg_timestamp = millis();
    m_waitingReply = false;
    return checkConnection();
}

4) calls checkConnection: endless loop

[MudiStar]

Interims Solution: comment out reset()

bool AsyncTelegram2::checkConnection()
{
    // Start connection with Telegramn server (if necessary)
    if (!telegramClient->connected())
    {
        m_lastmsg_timestamp = millis();
        log_info("Start handshaking...");

        if (!telegramClient->connect(TELEGRAM_HOST, TELEGRAM_PORT))
        {
            Serial.println("\n\nUnable to connect to Telegram server");
            //reset();
        }
#if DEBUG_ENABLE
        else
        {
        static uint32_t lastCTime;
            log_debug("Connected using Telegram hostname\n"
                      "Last connection was %d seconds ago\n",
                      (int)(millis() - lastCTime) / 1000);
            lastCTime = millis();
        }
#endif
    }
    return telegramClient->connected();
}

I'm running into resets on the ESP8266 again, like 15 times in 24h. The ESP placed next to the router Everything works fine on the ESP32.

@cotestatnt Is there a way you can help me out? I recorded more Exception Stacks for debugging.

[cotestatnt]

Hi @MudiStar First of all, I'm sorry for late reply but in this last months I was really busy at work.

I suspect this bug is actually "double". The reset due to the reset() statement (sorry for the pun) should be caused by a "death loop" that this statement introduces.

As for the reset which occurs once every 15h, I think it is due to the "delay" introduced by the failed connection with the Telegram server which can happen from time to time for the various reasons that trigger the ESP8266 software watchdog.

I'm trying out some recently introduced changes. As soon as I have positive results I also update the repository.

[cotestatnt]

Hi @MudiStar I just uploaded the edited file. I've been trying a sketch since this morning and it hasn't reset until now, looks promising.

To make it easier for me to manage this problem, I make sure that on reboot the esp sends me a message containing the cause of the last reset

extern "C" {
#include <user_interface.h> // https://github.com/esp8266/Arduino actually tools/sdk/include
}

void setup {
  .....
  ......
  rst_info *myResetInfo;
  myResetInfo = ESP.getResetInfoPtr();

  char welcome_msg[256];
  snprintf(welcome_msg, sizeof(welcome_msg),
    "myResetInfo->reason %x \nBOT @%s online\n/help all commands avalaible.",
    myResetInfo->reason,
    myBot.getBotName()
  );

  // Send a message to specific user who has started your bot
  myBot.sendTo(userid, welcome_msg);
}

Hello @cotestatnt

I'm happy that you "are back" ;-)

I compiled my two programs I'm using your library with. Fingers crossed. In the meantime, I've noticed that it seems to be stable just running your OTA example. If I add a webserver and some other non-blocking functions, everything starts getting unstable. Same code on the ESP32 works fine.

My WakeOnLan code is pretty straight forward. So no pin readings or something See attached picture. I couldn't find a pattern yet.

[MudiStar]

It is not working for me. Two restarts so far I try to get a stack dump

[MudiStar]

This doesn't happen if I'm just running the Webserver. My second Bot is running so far. Maybe you know what is going on

Exception 5: Alloca: MOVSP instruction, if caller's registers are not in the register file PC: 0x40100217 EXCVADDR: 0x00000000

Reset is triggered by Telegram connection because something seems to be blocking

Good morning @MudiStar I've just noticed you are running the latest esp8266 core version while mine was a little older. I'm triyng now with the latest too.

Unfortunately with the esp8266 there has always been this problem and I have never been able to really figure it out because I mainly use the esp32. I'll update you as soon as I have some more information about the issue.

[MudiStar]

I have an ESP8266 running without any problems since October with your version 2.1.6 after fixing a bug in just one line with an additional "if", it keeps crashing randomly The same line is ok running on the ESP32.

Maybe a library was updated simultaneously or I was just lucky that it was working Made no sense for me

If you need my code or something, feel free to ask
