I am very new to the ESP32 and just started discovering it.
As I would like to use it at my university I would like to connect it to eduroam (WPA2 Enterprise).
According to our support, I do not need any certificates. PEAP is used and data is encrypted with AES or TKIP.
I tried to run the WPA2 enterprise demo which is included in the current IDF and I am runninig the current IDF-version.
(Downloaded 2 days ago. I sadly don't know how to find out the actual version)
There I left the original .PEM, .CRT and .KEY files in the project folder and set the mode to PEAP.
I also tried to remove the certificates in the source code as they are not needed in my case as I understood.
In both cases I get a Guru Meditation Error.
For the first, where I had the certificates present I made a core dump.
Do you have any idea how to solve this problem or has anyone a working example how to connect to eduroam using IDF and not Arduino?
Thank you very much for the help!
Here the dump:
