|
|
* This task sets up the SD card and Ethernet devices,

|
|
* wolfSSL client connects to a server over TLS and sends
|
|
* a simple HTTP GET message, then prints out the reply
|
|
* from the server.
|
|
*
|
|
* To change the IP address and port of the server,
|
|
* change the wolfsslIP and wolfsslPort variables in
|
|
* client_test(). Note that wolfsslIP needs to be given
|
|
* in hexadecimal.
