WiFiUdp.h: How to Assign a Static IP Address to ESP32?

Hello
Uploading the following code:
.
then attaching the serial monitor, the IP is assigned randomly (practically different every day). Is it possible to assign a specific IP address by modifying the libraries accordingly?

In wifiudp.h instead of remoteIP() can I assign my address e.g. 192.168.0.214? If so, how do I write it down?

Added after 1 [hour] 1 [minute]: .

In WifiUdp.cpp I have this function:
.

Now I have no way to check it, but if I replace this function with:
.

solve the problem?

Hello, write again what you mean, because the attempted solution you presented has little to do with the question you asked. You can either set a fixed IP address for the client on a DHCP server (e.g. oi MAC number) or instead of DHCP configure it statically. I'm not familiar with the arduino, maybe Wifi.config()?

It is not necessary to modify the libraries. Link to an example with the possibility of assigning a static address to a WiFi client:
https://github.com/espressif/arduino-esp32/bl...les/WiFiClientStaticIP/WiFiClientStaticIP.ino

What I mean is that my ESP32 should have a fixed IP address, as I connect to it via different applications. For data exchange to be possible the ESP32 needs to know the IP address of the application and the application needs to know the ESP32 address.
The example shown is for communication over TCP/IP and there is no problem with that, but the UDP protocol allows for much faster data exchange and the point is that with UDP I can't set a static IP in any way



If I use the UDP library I always have a different IP than I would like. What I wrote earlier also does not work

Is this ESP supposed to operate in STA or AP mode?

The IP address is set for the IP layer, not for the higher layers, TCP or UDP.

This code, what you have shown in the image does not match what I wrote in post #3 - no WiFi.config() before WiFi.begin().

It wasn't until today that I was able to sit down to this quietly and indeed the solution was WiFi.config(local_IP, gateway, subnet);
.
