gpio_viewer reboots over and over ...

[phillipAB47]

I have installed the latest libraries but for some reason the sketch just reboots and reboots as shown next.

Installed library versions are as follows:
GPIOViewer > v 1.6.2
ESP Asyn WebServer > v 3.7.4
AsyncTCP > v 3.3.8
Espressif Systems > v 3.2.0

The microcontroller is an ESP32-WROOM-32D (36-pins)

Any help will be greatly appreciated.
Thank you.

I have tried the example provided with the library and there is no reboot.
Try the example on your side.
Which board are you using in the IDE ?

Thank you very much for your response.

I am using an ESP32-WROOM-32D microcontroller.
The sketch I am using is the gpioViewer example modified to add my own wifi code and credentials as shown next.

`#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);
}
'
As noted earlier the code compiles but after uploading it just reboots over and over so I never get the web link to view the controller. In the IDE I use the following board:

As can be seen the only difference from the original example and my sketch is that I added my own wifi code.
If I remove the three (3) gpio_viewer code lines the sketch will connect to wifi as shown next:

I sincerely appreciate your help.

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.
