Greetings,
If someone needs it - I've got a successful connection with eduroam, but there are few limitations:
- This code runs with the newest development Framework code 3.1 / 3.2 (beta),
- Paste your Certificate in
array,
- Fill code (or create a remote .h file) with your credentials,
- You have to wait a little bit to connect,
Code: Select all
