Francois Berder / Mbed 2 deprecated TLS_cyassl-Example2

This example show how to create a small TLS server using the TLS_cyassl library.

Dependencies:   EthernetInterface8 TLS_cyassl mbed-rtos mbed

Once you launched this program on the mbed, create a small python script :

TLS client

import httplib

conn = httplib.HTTPSConnection("10.2.200.35", 443)
conn.request("GET", "/")
r1 = conn.getresponse()
print r1.status, r1.reason
data = r1.read()
print data

In the terminal, your mbed prints its own IP address. Replace 10.2.200.35 with the IP address of your mbed.
