+# ESP32-Eduroam
+* Eduroam wifi connection with university login identity
+* Working under Eduroam networks worldwide
+* Methods: PEAP + MsCHAPv2
+
+# Format
+* IDENTITY = youridentity   --> if connecting from different university, use youridentity@youruniversity.domain format
+* PASSWORD = yourpassword
+
+# Usage
+* Change IDENTITY
+* Change password
+* Upload sketch and enjoy!
+* After sucessful assign of IP address, board will connect to HTTP page on internet to verify your authentification
+* Board will auto reconnect to Eduroam if it lost connection
