i am using the WiFi.h library with ESP32S3 (Arduion IDE 2.2.1) to get the dynamic MAC-Address of the ESP32S3.
I need the MAC-Address to establish a communication through Ethernet.
I had no problem with that till yesterday.
Since that when i compile with the WiFi.h library i get a lot of error messages.
I will put some of them here:
C:\Users\user\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.0.1\libraries\WiFi\src/WiFiGeneric.h:44:25: error: 'network_event_handle_t' does not name a type; did you mean 'esp_event_handler_t'?

41 | #define WiFiEventCb NetworkEventCb
C:\Users\user\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.0.1\libraries\WiFi\src/WiFiGeneric.h:80:41: error: 'arduino_event_id_t' has not been declared
80 | void removeEvent(WiFiEventCb cbEvent, arduino_event_id_t event = ARDUINO_EVENT_MAX);
C:\Users\user\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.0.1\libraries\WiFi\src/WiFiGeneric.h:43:25: error: 'NetworkEventSysCb' has not been declared
43 | #define WiFiEventSysCb NetworkEventSysCb
And so on.
I changed the Additional Board manager URL that i have, it didn't help.
I searched on the net and found some threads having similar problem.
They suggest to delete the folder in this path:
C:\Users\user\Arduino\hardware\espressif\esp32\
and then add the URL (Stable release link) newly from the espressif site.
But i do not have such a path.
I think you should post the complete code that is giving you this problem.
The errors you reported point to code that is part of the core, so if the installation of the release v3.0.1 was done successfully, you should have no problems with these sources.
If in doubt, try to completely delete the C:\Users\user\AppData\Local\Arduino15\packages\esp32 folder and do a new core installation from scratch.
Try rolling back your Board platform -- probably "esp32" -- from 3.0.1 to 2.0.17. Avoid major version upgrades in the middle of a project.
It's odd that the error is for this macro #define: "if you see this text, replace it with this other text". Why is that replacement text being evaluated here?
One of the changes in v3 is renaming WiFi stuff to Network stuff; e.g. WiFiClient is now NetworkClient. This name is accurately covers more kinds of networking. These macros are declaring substitutions from the old types to the new types, so that they work with existing code. Just above those lines is
#include "Network.h"
which can be found in /libraries/Network/src, and that file contains
#include "NetworkEvents.h"
which is in the same directory, and defines NetworkEventSysCb and the others. Usually if an included file is missing the compile will terminate on that, because there's really no point going further.
Thank you all for your replies. @Juraj i am using W5500. @StefanL38 core-Version 3.0.1 @cotestatnt i have tried that and deleted the completely folder, that didn't help. @kenb4 i did what you have suggested but not the hole core, only the wifi library i downgraded to 1.2.5
Now i do not get those error messages.
The idea behind this is the following:
I want to retrive the dynamic MAC-Address when power is on and this save it to the falsh and use it with the Ethernet.
The problem is what if i do not have i WiFi nezwork, then how can i get the dynamic mac with the Ethernet?
I am using the "EthernetWebServer.h" which do need a mac-address at the beggining to connect.
Any ideas please.

You're confusing it. The MAC address is a "hardware" code that uniquely identifies an ethernet device and you do not need to be online precisely because it is a property of the device itself.
You are using a W5500 shield, so basically you have to set MAC address via software and you can use whatever you like.
If you want to make sure you use an address that won't cause you problems, you might think about using the MAC address of the WiFi adapter already included in your ESP32 card, but it's just a refinement.
Yes i did.
It is not so easy for me to replace the library i am using with a new one, but i will give it a try.
You may provide an example related to the issue here, please.
Thanks
OK.
I want that the ESP32 keeps the unique MAC that it has gotten from the manufacturers.
I do not want to set any MACs, i just wanted to read the original one.
But i will try your library.
