Hello
I switched to FirebaseClient. I think I’ll be able to use error checking.
if (aResult.isError()) {
Firebase.printf(“Error task: %s, msg: %s, code: %d\n”, aResult.uid().c_str(), aResult.error().message().c_str(), aResult. error().code());
Serial.println(“Error received!!!!!!”);
delay(10000);
//ESP.restart();
//WiFi.reconnect();
//FirebaseApp.getRefreshToken();
}

Hi Sara
Thank you very much for your useful teachings.
You were directed to this tutorial for the Firebase timeout error.
I applied the Wifireconnect plugin, but I still get the timeout error.
Is there a way to try again when I get a timeout error in Firebase?
Thanks

Specifically, only if I select the Arduino Uno board.

Both codes work. But after compiling, loading and resetting, my ESP connects to wifi only if I simply change the board to arduino IDE 2.board is ESP-WROOM32.Ai idea why this happens?

Hi,
Just noticed that in my sketch, I used both wm.setwifiautoreconnect(true) and WiFi.reconnect() simultaniously. This was the issue. Using only WiFi.reconnect is working fine with WiFiManager.h
Thanks

Hi,
I am using WiFiManager.h on an ESP32.
Would the sketch ( WiFi.disconnect(); WiFi.reconnect(); ) also work to reconnect, or is there any other way to reconnect ? I tried using wm.setWifiAutoreconnect (true) but this seems not to work.
Thanks.

In reply to Larry. I have the same problem with the same error on VSCode. Do you have a solution? Thanks, Udo

In reply to Larry. I finally solved the issue with not compiling on the arduino.ide. I deleted the arduino.ide and reinstalled it. The sketch worked without any issues. I still cannot get it to compile on vscode/platformio. I will continue to try and solve that problem. I think it may have something to do with the way the functions are not declared in the sketch.

Hi Everyone,

I have a problem with the raw sketch, When I try and compile it in the Arduino IDE or
In vscode it will not compile. It gives me the following error:

I have tried everything I can think of, but no luck. I hope someone can help
Thank you.

Hi.
It’s easier if instead of blinking, you turn on and off the LED.
You just need to add the lines to light up the LED in the WiFiStationDisconnected() function, and the instructions to turn it off inside the WiFiStationConnected() function.
I hope this helps.
Regards,
Sara
