Just send a notification to system tray:
  • Create a nag app on Windows with the purpose of showing push notifications.
  • Teach the ESP32 to send a Windows Push Notification to your app: https://docs.microsoft.com/en-us/window ... --overview
  • Figure out how to permit Windows to show you the push notification during gaming.

I just had a quick search on the internet to see if it might be possible to use Processing to act as a web server - I thought it unlikely but turns out it is really easy to do :-)
see: https://processing.org/discourse/beta/n ... 28867.html

So you could modify the above Processing sketch to run on your PC which when the ESP32Cam sends a html request it triggers the processing sketch to alert you in whatever way you require. Maybe not a technically impressive solution but should be pretty quick/simple set up.

BTW - I have a sketch which I use as a starting point for my esp32cam projects which may be of interest if you are new to the esp32cam (and using ArduinoIDE): https://github.com/alanesq/esp32cam-demo

In this you would send such a request with a command in the format:
ip address, page to request, port to use (usually 80), maximum chars to receive
i.e. requestWebPage("192.168.1.100", "/?trigger1", 80, 600);

------
update:

I have modified the Processing sketch (below) so that if you add ?trigger1 or ?trigger2 on the end of the URL it pops up a message confirming the command was received

Code: Select all


import processing.net.*;

String HTTP_GET_REQUEST = "GET /";
String HTTP_HEADER = "HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n";

Server s;
Client c;
String input;

void setup() 
{
  s = new Server(this, 8080); // start server on http-alt
}

void draw() 
{ 
  c = s.available();
  if (c != null) {
    input = c.readString();
    input = input.substring(0, input.indexOf("\n")); // Only up to the newline
    
    if (input.indexOf(HTTP_GET_REQUEST) == 0) // starts with ...
    {
      c.write(HTTP_HEADER);  // answer that we're ok with the request and are gonna send html    
      // reply html
        c.write("<html><head><title>Processing demo</title></head><body>\n");
        c.write("<h3>Processing trigger from web demo</h3>\n");
        c.write("</body></html>\n");
      // close connection to client, otherwise it's gonna wait forever
        c.stop();   
    }
    
    // actions triggered by web page request
      // trigger by     http://localhost?trigger1
        if (input.indexOf("?trigger1") > 0) {
          javax.swing.JOptionPane.showMessageDialog(null, "trigger 1 received");       // show a popup message
        }
      // trigger by     http://localhost?trigger2
        if (input.indexOf("?trigger2") > 0) {
          javax.swing.JOptionPane.showMessageDialog(null, "trigger 2 received");       // show a popup message
        }      
  }
  
}

​I was searching for a similar data, had a go at doing likewise yet it didn't worked.
