ESP32 As A TCP Server

[Jacky Chiang]

Hello, everyone.
I'm now trying to use ESP32 as a TCP server. But I have some question.
That's can I use ESP32 as a TCP Server without any other Wifi source ?
I was searching online for some instruction and found this one : "http://www.iotsharing.com/2017/05/tcp-u ... esp32.html"
It seems like he use the ESP32 as a tcp server but still need a wifi machine to provide an wifi source.
I am wondering if i can do it without the wifi machine ??

thanks !!

Yes, you can set the ESP32 into access point mode so other devices can connect to it, then start up your TCP server as usual.

Then may I request some places to find sample codes of it with Arduino IDE.
I've tried many places but gained nothing ~
There are a lot about web server but few about TCP server .
Thanks !!!

... use the ESP32 as a tcp server but still need a wifi machine to provide an wifi source...

Web Server is TCP server. What is wifi machine ? What do you intend to serve with your TCP server?

I wanna remove the Web layer from TCP layer for having more flexibility and not being limited by the Web layer structure.
The layer structure is shown in the figure of this website :

Hi

this is a good explanation about how to implement a TCP server with netconn... the HTTP layer is just the way you manage the incoming messages ("GET..."):
