Not working on ESP32

[SHIINA96]

I'm trying to run your code on my ESP32 Dev Module, and I can't compile the code. Here is what I get from the IDE

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Any help appreciated.

Try to swap the referrence of ethernet.h in Packet.h to WiFi.h.

[SHIINA96]

It works but causes by the silly enterprise wifi, I gonna try it later.

[sand007man]

OK do let me Know once it is Working, even i am working with esp 32 :)

[SHIINA96]

Hi, I meet a new problem When I try to connect wifi, then monitor will print "Couldn't get a wifi connection" I checked the SSID or password, they both fine But when I upload others project which also using WiFi.h, the ESP32 connected to wifi successfully Any help?

That isn’t a message from the connector. That appears to be from the ESP WiFi library. Be sure to check for conflicts and ensure you’ve modified the connector header file correctly.

I found that the variable ' statue ' didn't work properly. After I changed the whole WiFi connection part, the problem was fixed.
