I'm having issues with the basic functions of my CC3000BOOST. I tried using the Energia software library for programming the EK-TM4C123GXL and the basic programs work (BLINK, FADE etc) but when I try to test wireless (with the simplewebserver example) I never get any response signifying connectivity and the website is not accessible. The sample code is posted beneath. I'm thinking software issue but am open to other suggestions for troubleshooting.
// Enter here the name (=SSID) and password of your WiFi LAN
#define WLAN_SSID "energia" // cannot be longer than 32 characters!
#define WLAN_PASS "supersecret"
/*
Web Server
A simple web server that shows the value of the analog and digital input pins
using a WiFi BoosterPack.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
Circuit:
* WiFi BoosterPack
