ST / Mbed 2 deprecated HTTPClient_HelloWorld_IDW01M1

HTTP/HTTPS client Hello World application running with X-NUCLEO-IDW01M1v2 wifi board.

Dependencies:   HTTPClient NetworkSocketAPI X_NUCLEO_IDW01M1v2 mbed

Fork of HTTPClient_HelloWorld by ST Expansion SW Team

Example of HTTP and HTTPS connections 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).
For HTTPS connection it uses the TLS/SSL feature provided natively by the Wi-Fi module and performs secure connection to the server 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.
