MQTT Connection Skip a second or RC -2 or -3

leejames92 commented 2 years ago

Hi,

I have this issue of which I am unable to solve thus far. My ESP8266 paired with Arduino Mega and DS3231 RTC is setup to publish data every second to thingsboard IOT online through my home WiFi.

Most times per second works fine, but occasionally it would skip a second and after 12 hours or so (sometimes sooner) it would disconnect (but able to reconnect). I would like to eliminate the skip a second + the MQTT disconnect entirely to be able to say my system is stable and reliable.

Sample of sketch in Arduino,

    status = WiFi.begin(WIFI_AP, WIFI_PASSWORD);
    delay(500);

  Serial.println("Connected to AP");

}

void reconnect() {

  while (!client.connected()) {
    Serial.print("Connecting to Thingsboard node ...");
    // Attempt to connect (clientId, username, password)
    if ( client.connect ("James1992SSM", "James", "920810abcde") ) {
      Serial.println( "[DONE]" );
    } else {
      Serial.print( "[FAILED] [ rc = " );
      Serial.print( client.state() );
      Serial.println( " : retrying...]" );

    }
  }

void WiFiLoop () {

  status = WiFi.status();
  if ( status != WL_CONNECTED) {
    while ( status != WL_CONNECTED) {
      Serial.print("Attempting to connect to WPA SSID: ");
      Serial.println(WIFI_AP);
      //Connect to WPA / WPA2 network
      status = WiFi.begin(WIFI_AP, WIFI_PASSWORD);
      delay(500);
    }
    Serial.println("Connected to AP");
  }

  if ( !client.connected() ) {
    reconnect();
    client.loop();
  }

}

In the loop I've disregarded for now to use WiFiLoop() as this would attempt to reconnect loss MQTT.

My ESP8266 is connected to stable WiFi connection so I'm trying to figure out why its disconnecting at random times and skipping seconds at random times. I want my connection to be stable and no loss first.

My ESP8266 is flashed to latest:

AT version:1.7.4.0(May 11 2020 19:13:04) SDK version:3.0.4(9532ceb) compile time:May 27 2020 10:12:17 Bin version(Wroom 02):1.7.4 OK

Set to max RX and TX power.

A quick debug so far showing an example it skipped a second:

As you can see above bolded seconds can see a 1 second skip. I really don't know why is this happening.

Is it because of the baud rate? or a delay in a sketch? I tried many possible solutions but to no avail :(

Please help thank you.

JAndrassy commented 2 years ago

maybe first fix the presented sketch. variable seconds is not declared. global variables are shadowed by local variables... please edit the original post.

Hi jassandry,

Thanks for the find. I've just amended in my code and testing now.

However, this is an error log I've captured using the original code and the MQTT connection broke,

I am unable to decipher the issue based on this log. Do hope I can get some clarity and assistance. Looks like there is a send fail, then send once ok after skipping couple of seconds, then the MQTT connection broke right after.

JAndrassy commented 2 years ago

AT firmware responded SEND FAIL. there is no more info

leejames92 commented 2 years ago

Meaning there is an issue with my sketch? Sorry i'm quite unfamiliar still with this MQTT related matters

JAndrassy commented 2 years ago

I guess not. What version of AT firmware is it?

leejames92 commented 2 years ago

AT 1.7.4.0

Is it esp8266 wifi connection cut off or its busy?

JAndrassy commented 2 years ago

AT 1.7.4.0 Is it esp8266 wifi connection cut off or its busy?

1.7.4 is the best ESP AT firmware ever (I doubt AT 2 can be so stable in near or far future), but event then it can have problems for various reasons. Does the next sending work?

leejames92 commented 2 years ago

I see. I tried again and after 8 hours the MQTT connection broke again :/

Again it is seen that the esp is busy first. and then the connection just break :(

Does the next sending work?

leejames92 commented 2 years ago

Sorry, what do you mean by next sending? Is it restart my arduino mega and esp8266? if that, yes it work.

Also if I include reconnect after MQTT connection loss, that'll work as well I believe.

leejames92 commented 2 years ago

Maybe I think you meant my client.state()? It becomes - 3.

When it becomes -3 then it loops without sending anymore

esp> AT+CIPSTATUS ...sent
esp> STATUS:4 ...matched

status 4 is "The TCP or UDP transmission of ESP8266 Station is disconnected" which is expected, because the TCP connection closing was announced by AT firmware here

esp> busy s... ...ignored
esp> 4,CLOSED ...processed

but there is no new connection attempt. I don't know what code you run. maybe the cloud kicks you out for too frequent calls.

leejames92 commented 2 years ago

I see. I'm disappointed with self unable to solve this issue.

However I bought a WeMos arduino mega with installed on board esp8266 and hopefully it'll work when it arrives. Maybe my current setup esp8266 isn't getting enough power.
