Hi everyone ! :)

I’ve got an issue with my server web socket. An abstract scheme of the socket is: Socket: {

Loop(); // Data acquisition TableUpdate(); // with new data if(userRequest == true)

SendTable(); // sends the table to the web browser

}

 

The point is that, if the user doesn’t send a request for 4-5 seconds Loop() is not run. I need Loop to be executed also if there’s no user request for the socket. It seems that the socket is in stand-by, waiting for a new request. If you want I can write the code. Thank you for your help.

Hi It is hard to tell from your code but I would guess that the socket is blocked listening for an incoming connection. That is why loop only runs when the browser opens a connection. There are examples on this site on how to put blocking code into a thread. Can't search as I'm mobile. Cheers

Thank you for your answer. I'm looking for examples in this site on how to put blocking code into a thread, but I couldn't find. If you can write a link it would be great.  

The only thing I found in this forum about this issue is that I should use threads, but I've got no experience with threads.

Wish you can help me :) Thank you again...

 

Cheers

Have a look at any or all of these. There is a lot of detail in some of these great projects but the main webservers demonstrate what you need to understand.

Cheers
