We don’t have any tutorials about that specific subject.
If you provide more details about what you want to do, maybe we have other tutorials on similar subjects that might help.

Hi you,

I want to send Hexa bytes from phone to esp32 using Wifi

Hi.
Maybe this web server example might help: 

Input Data on HTML Form ESP32/ESP8266 Web Server using Arduino IDE

It creates a web server with a form that you can fill with whatever info you want to send to the ESP32.
 
 
 
I hope this helps.
