WebClient

The WebClient sketch does a test of the TCP client capability:

Initialization
Optional SSID Scan (uncomment code section to enable)
Access Point connection
DHCP address assignment
DNS lookup of www.adafruit.com
Optional Ping of www.adafruit.com (uncomment code section to enable)
Connect to website and print out webpage contents
Disconnect

The sketch connects to www.adafruit.com and opens a special webpage we have prepared for this example. It reads the contents of the page and prints that out to the Serial Monitor.

Before you run the sketch, edit it to replace the dummy SSID and password with your own:

Download File

Copy Code

#define WLAN_SSID       "yourNetwork"        // cannot be longer than 32 characters!
#define WLAN_PASS       "yourPassword"

#define WLAN_SSID       "yourNetwork"        // cannot be longer than 32 characters!
#define WLAN_PASS       "yourPassword"

Also, make sure that the right wireless security scheme is selected (unsecured, WEP, WPA, or WPA2)

Download File

Copy Code

// Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2
#define WLAN_SECURITY   WLAN_SEC_WPA2

// Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2
#define WLAN_SECURITY   WLAN_SEC_WPA2

Here's a sample of the Serial Monitor output of WebClient. You should see something similar:
