Multi-Hackers / Axeda_IoT_Connection_Example

A simple client that allows the user to send Json data to Axeda's IoT cloud using an SSL socket (with certificate verification).

Dependencies:   mbed

Only allows use of URLs, not IP addresses. Most CyaSSL errors are caused by incorrect certificates or failed certificate verification (188, 151, 155).
