I solved it by replacing:

esp_wifi_sta_wpa2_ent_enable();

with:
esp_wpa2_config_t config = WPA2_CONFIG_INIT_DEFAULT();
esp_wifi_sta_wpa2_ent_enable(&config);

I also added my university email as EAP id, then I was able to connect.

Hello,

I tried removing the wifi-library but was not able to compile the code. I still got the error:

sketch_sep25a:29: error: too few arguments to function 'esp_err_t esp_wifi_sta_wpa2_ent_enable(const esp_wpa2_config_t*)'

What versions of each libraries are you using? Could you also please ...
