My friend I don't want to create scripts/executable
You'll need to get over that, eventually.
I just want the message the to appear while I'm sending this message
Appear where? What wireshark is looking at is data that the httpd daemon is getting. No httpd == no wireshark data.
the other device should have to detect a specific message throw the web
What other device? How is it connected? What software is it running?
I have opened already the TCP frame in the wireshark and still there is no data into it , why ?
Because there is no http daemon running to generate the data? I don't know. You didn't answer all of my questions.
what is my exact problem ?
Because not being able to answer all the questions? I don't know, without answers to the questions I asked.
how can I solve it ?
The first step is to admit that you have a problem. OK, you've done that.
The second step is to define exactly what the problem is. You seem clueless there.
other thing while I opened the serial monitor to see how it's worked I saw the device working slowly what is the problem exactly
The Arduino is working, and that is a problem? How?
