buildtest
The buildtest sketch does a full test of core WiFi connectivity:- Initialization
- SSID Scan
- Access Point connection
- DHCP address assignment
- DNS lookup of www.adafruit.com
- Ping www.adafruit.com
- Disconnect
Before you run the sketch, edit it to replace the dummy SSID and password with your own:
Download:
file
#define WLAN_SSID "yourNetwork" // cannot be longer than 32 characters! #define WLAN_PASS "yourPassword"
If you're using WEP, the password should look like this:
const char WLAN_PASS[] = {0x1A, 0x2B, 0x3C, 0x4D, 0x5E, 0x00};
Since it's a collection of bytes not 'passphrase' style key
const char WLAN_PASS[] = {0x1A, 0x2B, 0x3C, 0x4D, 0x5E, 0x00};
Since it's a collection of bytes not 'passphrase' style key
Also, make sure that the right wireless security scheme is selected (unsecured, WEP, WPA, or WPA2)
Download:
file
// 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 buildtest. You should see something similar:

Make sure you can see and recognize all of the access points around, connect to the access point, get a good connection with DHCP, can do a DNS lookup on www.adafruit.com and ping it successfully. If all this works, then your hardware is known good!
