Connect a secure socket with TLS server authentication through X-NUCLEO_IDW01M1 Wi-Fi.
Dependencies: NetworkSocketAPI X_NUCLEO_IDW01M1v2 mbed
Fork of
HelloWorld_IDW01M1v2
by 
ST
Example of TLS connection using X-NUCLEO-IDW01M1 Wi-Fi expansion board.
The application is meant to be used with mbed OS 2 ("Classic") only (no mbedOS 5 support).
It uses the TLS/SSL feature provided natively by the Wi-Fi module and performs secure connection to https://mbed.org also verifying the server identity.
To avoid expired CA certificates, system time (in epoch) must be manually entered (e..g. using http://www.epochconverter.com/ ) .
Retrieval of current time from an NTP server is shown by this example.
