Communication serial direct between to esp32

[salento1201]

Hi, I have a two esp32 and I would like to program using ide arduino, my project is to create a wifi network and that the other connects, the two esp and you should exchange data or at least one that sends data and the other execute (for example, a potentiometer is connected to the espA instead the espB receives the value of the potentiometer)
I tried to create one as Accesspoint and the other client but I can not get data sent.
I had thought to configure the esp32 as AP + Station (I think it's not possible with this model) but anyway I used the directives (# if, # else and #endif) but nothing gets stuck after the AP configuration
