ESP32_EDUROAM.ino

/*|----------------------------------------------------------|*/
/*|Connection sketch to eduroam network (WPA/WPA2) Enteprise |*/
/*|Suitable for almost any ESP32 microcontroller with WiFi   |*/
/*|Raspberry or Arduino WiFi CAN'T USE THIS LIBRARY!!!       |*/
/*|Edited by: Martin Chlebovec (martinius96)                 |*/
/*|Compilation under 2.0.3 Arduino Core and higher worked    |*/
/*|Compilation can be done only using STABLE releases        |*/
/*|Dev releases WILL NOT WORK. (Check your Ard. Core .json)  |*/
/*|WiFi.begin() have more parameters for PEAP connection     |*/

//WITHOUT certificate option connection is WORKING (if there is exception set on RADIUS server that will let connect devices without certificate)
//It is DEPRECATED function and standardly turned off, so it must be turned on by your eduroam management at university / organisation

//Connection with certificate WASN'T CONFIRMED ever, so probably that option is NOT WORKING

#include <WiFi.h> //Wifi library
#include "esp_eap_client.h" //wpa2 library for connections to Enterprise networks

#define SKOLEMAIL "[email protected]"
#define KODEORD "DetHerErIkkeMitKodeord"

// MAKE SURE THAT YOU TRUST THE ACCESS POINT, BECAUSE WE ARE NOT USING CERTIFICATES TO VALIDATE THEM!
// SO ANYONE PRETENDING TO BE "EDUROAM" WILL SEE YOUR PASSWORD!

//Identity for user with password related to his realm (organization)
//Available option of anonymous identity for federation of RADIUS servers or 1st Domain RADIUS servers
#define EAP_ANONYMOUS_IDENTITY "[email protected]" //[email protected], or you can use also [email protected]
#define EAP_IDENTITY SKOLEMAIL //[email protected], at some organizations should work nickname only without realm, but it is not recommended
#define EAP_PASSWORD KODEORD //password for eduroam account
#define EAP_USERNAME SKOLEMAIL // the Username is the same as the Identity in most eduroam networks.

//SSID NAME
const char* ssid = "eduroam"; // eduroam SSID
