Problem Description

My program randomly crashes while trying to post data via WifiClient.
Sometimes at client.connect(), sometimes at client.println(), but always latest stack trace points to millis and _yield
Sometimes program can run hours without crashes, sometimes few minutes.

Sketch

void wyslijPomiar()
{
  Serial.println(F("wyslijPomiar"));
  WiFiClient client;
  unsigned long connectStart = millis();
  if (!client.connect(adresSerwera, portSerwera)) { //sometime crashes here
      Serial.println(F("Brak połączenia z serwerem"));
      return;
  }
  client.flush();
  client.setNoDelay(true);
  bool aktualizuj = false;
  String PostData ="pm1_0_std=" + String(PM01Avg);
  PostData += "&pm2_5_std=" + String(PM25Avg);
  PostData += "&pm10_std=" + String(PM10Avg);
  PostData += "&pm1_0=" + String(PMa01Avg);
  client.println(F("POST /esp/upload.php HTTP/1.1"));
  client.println("Host: "+ String(adresSerwera));
  client.println(F("Cache-Control: no-cache")); //sometime crashes here
  client.print(F("Authorization: Basic "));
  client.println(base64::encode(AUTH));
  client.println(F("Content-Type: application/x-www-form-urlencoded"));
  client.print(F("Content-Length: "));  //sometime crashes here
  client.println(PostData.length());
  client.println();
  client.println(PostData);
  unsigned long timeout = millis();
  while (client.available() == 0) {
    if (millis() - timeout > 5000) {
      Serial.println(">>> Client Timeout !");
      client.stop();
      return;
    }
  }
  while (client.available()|| client.connected()) {
    String line = client.readStringUntil('\r');
    //Serial.println(line);
    if (line.indexOf("Wersja") >= 0) //sprawdzanie wersji
    {
      String wersja = line.substring(8, 11);
      Serial.print(F("Wersja:"));
      Serial.println(wersja);
    }//sprawdzanie wersji
  }
  if (client.connected()) {
    client.flush();
    client.stop();
  }
  Serial.println(F("Dane wyslane"));

Are you using the wifi events? E.g. is wyslijPomiar() called from a callback?

@devyte No, wyslijPomiar() is called from main loop, in ~120 seconds interval. I'm using millis and comparing it, not using delays.

What I can say with your logs is that the STA interface is disconnected just before the crash.
It is like our network layer can't see when the interface is not there anymore.
It seems to be related with #5245 and #5239.
All these issues are appearing not long after nonos-sdk-pre3 update #5210. Maybe related or not.

Bug reproduced. fw-pre3 has a different behaviour when wifi disconnects.

@mateusz-szafraniec I think this will be fixed by #5254.
This issue seems to be unrelated with nonos-sdk update.
