Sorry, I'm new here, I'm having a memory problem, as each reconnection test consumes more memory.

[tablatronix]

Will test thanks

[tablatronix]

I am assuming you have removed your local callouts to timeClient, ping, client checks and you are not leaking memory in them ?

[tablatronix]

Make sure you are pulling git, there was an esp8266 fix recently

I am calling autoconnect in a loop and not leaking any memory.. Are you using blocking or non blocking mode? Let me try esp8266

[RulioHT2021]

Sorry I wasn't so clear, after connecting the network I turn off the router and with each reconnection attempt with the router turned off it consumes memory. I'm using it without blocking.

[tablatronix]

Ok so the configportal is starting each time? How do you get out of it, do you have a timeout?

and how do you know its not your code?

timeClient.update();
ping_test();

[tablatronix]

Not seeing it, what exact hardware you using ?

[RulioHT2021]

`bool ping_test(){ bool success = Ping.ping(p_url, 1); float avg_time_ms = Ping.averageTime(); if (success) { resp = "{\"avg_ping\":\"" + String(avg_time_ms) + "\"}"; } else { resp = "{\"avg_ping\":\"erro\"}"; } return success; }

if(((millis() - time_conect_broker) >= 60000)||(timeClient.getSeconds() == 50)){ Serial.println("Tempo atingido!"); time_conect_broker = millis(); digitalWrite(LED, HIGH); if(!client.connected()){ Serial.println("Chamando task_reconnect"); xTaskCreate( task_reconnect, //Nome da função "task_reconnect", //Nome da tarefa 10000, //Tamanho da tarefa NULL, //Parametros 2, //Prioridade NULL //Handle ); }else{ Serial.println("Conectado!"); } } `

[RulioHT2021]

I make a routine to check if 60 seconds have passed or if the timestamp is correct when it is 50 seconds, and I leave it inside the main loop.

[tablatronix]

Are you sure your tasks wrappers are cleaned up after each ? Sounds like it could be leaking there

[RulioHT2021]

I'll need to test other routines, I'll get back to you as soon as possible. Thanks.

I created a task to reconnect and as you can see, each call consumes a little memory after wm.autoConnect(ssid, password); The scenario I'm testing is: in case there is a power outage and the router does not come back on. Sooner or later it will restart due to lack of memory. The problem is that I'm running a routine that cannot be restarted.

[tablatronix]

Just set WM debug level to WM_DEBUG_MAX it will dump heap stats

[tablatronix]

Looks like leaking 1440 bytes, hmm I was not seeing this the other day.

[tablatronix]

I cant find it yet, but my memory jumps up and down but stays <100% so something is cleaning up, but maybe not under certain conditions. I will have to run memory deugging and find what on the heap. I thought It was the known DNSD issue but that might only be a tiny bit.

Do you have many AP found during scans? Are you using hostname or mdns? If you change the configportaltimeout to like 20 seconds does anything change memory wise?

I might also want to copy your config, what partition config are you using, and what esp32 and rev ? I am testing on an S3 with default partitions

[RulioHT2021]

partitions: LITTLEFS

If you change the configportaltimeout to like 20 seconds does anything change memory wise? yes, Do not change

Are you using hostname or mdns? no

[RulioHT2021]

I changed the code this way and solved the consumption problem.

void task_reconnect(void * parameter){
  Serial.print("ESP.getFreeHeap(): ");
  Serial.println(ESP.getFreeHeap());
  WiFi.begin();
  timeClient.begin();
  //wm.autoConnect(ssid, password);
  Serial.print("ESP.getFreeHeap(): ");
  Serial.println(ESP.getFreeHeap());
  if(WiFi.status() == WL_CONNECTED){
    Serial.println("WIFI OK");
    timeClient.update();
    ping_test();
    Serial.println(resp);
    if(client.connected()){
      Serial.println("BROKER OK.");
      timeClient.begin();
    }if(client.connect((char*) s_id.c_str(), mqttUser, mqttPassword)){
      Serial.println("BROKER RECONECTADO.");
    }else{
      Serial.println("ERRO BROKER não RECONECTADO.");
    }
  }else{
    Serial.println("ERRO WIFI não conectado");
  }
  vTaskDelete(NULL);    // Delete task
}

[tablatronix]

Yeah I am not really sure what the issue is.. I will keep testing

My memory does this if i autoconnect loop
