Wifi loss stops my Voltage measurment

raymen2510 · August 17, 2023, 10:46am

Wifi loss stops my Voltage measurment. It is a Problem in the Philipinnes. It can be for hours in worst case. Reconnect my Wifi works fine !! All following code stops working until Wifi is back. I need all code working permanent , also if Wifi is Offline.
Thanks in advance for any help.

Your code looks nice, blocking but nice and well annotated. I took a quick look suspect you are getting caught up in your first line of code in your main loop. You have" if (WiFi.status() == WL_CONNECTED) {...} kyou need to add } elsse { before the closing "}" what you want it to do. I am not a coding expert so this is just an educated guess on my part.

raymen2510 · August 18, 2023, 5:55am

i changed the code part. But it doesnt make a difference. Voltage meassurment still stops.
Maybe you can give a advice how to change this.

void loop() {
  //-------------------------------------------------------------------------------------------
  if (WiFi.status() != WL_CONNECTED) {
    lcd.setCursor(0, 1);
    lcd.print("               ");
    lcd.setCursor(0, 1);
    lcd.print("WiFi lost.....");
    connectWiFi();
  } else {
    //if (WiFi.status() == WL_CONNECTED) {
    lcd.setCursor(0, 1);
    lcd.print("               ");
    lcd.setCursor(0, 1);
    lcd.print(WiFi.localIP());
  }

i am not sure but it seems the problem is the WHILE in following code. The problem if i take out WHILE the wifi doesnt reconnect.

void connectWiFi() {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
  }
}

Grumpy_Mike · August 18, 2023, 6:56am

You need to remove the while because that will wait for as long as the WI-Fi is down.

What you should do is just check the Wi-Fi status and then move on each time through your main loop function. Set a flag and use that to bypass anything that would normal access the Wi-Fi.

raymen2510 · August 18, 2023, 7:43am

can you please give me example with the flag . by the way if i remove the While the wifi doesnt reconnect

Grumpy_Mike · August 18, 2023, 9:13am

Then try:-

void connectWiFi() {
long unsigned int timeStart = millis();

  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED ||  millis() - timeStart  > 2000) {
    delay(100);
  }
}

That will slow you code down by only two seconds as it sees if it can connect again.

You have a flag already it is WiFi.status()
