gpio_viewer will not connect to wifi

[Phillip]

this is what I see in the serial monitor:

I have downloaded the GPIOViewer v1.6.2 and the ESPAsyncWebServer from the GITHUB webpage.
The AsynTCP library was installed via the Arduino IDE.

The sketch is based on the GPIOViewer example and is as follows:

Code: Select all

// #define NO_PIN_FUNCTIONS

  #include <gpio_viewer.h> // Must me the first include in your project
  GPIOViewer gpio_viewer;

  #include "config.h"
  #include <WiFi.h>
  
  const int LED = 5;

  void setup()
  {
    Serial.begin(115200);
    delay(1000);

    pinMode(LED, OUTPUT);
  
      WiFi.mode(WIFI_STA); //Optional
      WiFi.begin(ssid, password);
      Serial.println("\nConnecting");
  
      while(WiFi.status() != WL_CONNECTED){
          Serial.print(".");
          delay(100);
      }
  
      Serial.println("\nConnected to the WiFi network");
      Serial.print("Local ESP32 IP: ");
      Serial.println(WiFi.localIP());

    // Must be at the end of your setup
    // gpio_viewer.setSamplingInterval(25); // You can set the sampling interval in ms, if not set default is 100ms
    gpio_viewer.begin();
  }

// You don't need to change your loop function
  void loop() {
    Serial.println("\n ... in loop() .......");
    delay(10000);
  }

Any help will be greatly appreciated.
Thank you.

If you look in the example for gpioviewer, it lists the known working versions of the various components. Make sure you are using those versions. This may very well mean you need to use git to download the correct version.

Thank you for your help.

I think I have the latest working versions for all the components required as follows:

The Espressif Systems version will follow.

And lastly, here is my current version of Espressif Systems Core

What device?

[Phillip]

I am using an ESP32-WROOM-32D (36-pins) as shown next:

I got this to work by replacing the required GPIOViewer libraries from the latest installed versions back to the "Last tested on:" library versions noted in the GPIOViewer example app.

While I am overjoyed that I now know how to get this to work, I find it odd that the latest library versions will not work with the GPIOViewer library. I hope I am wrong about this but that is my experience at the moment.

Thanks.
