Hi,
I made a program to configure my ESP via UDP. Esp answer to commands that I send normally and by broadcast. And i got a question. Is it possible to made udp socket listen on all adress in 192.168.x.x even if esp didnt have adress from DHPC server?

Good question! Seems like I will do something like this in the nearest future

didnt have adress from DHPC server

Do you mean that IP address is assigned by the ESP32 itself? I think that in general ESP32 will have IP address. Maybe I will also need to try multicast. As I understand, multicast support is implemented in router (ESP32 in our case). Something like mDNS?
