Arduino UNO + CC3000 WiFi Module

This demo is CC3000 module for the WiFi communication, uses the examples code "EchoServer.ino", it connects to the access point, get a connection with DHCP.

Board : Arduino Uno
Module : CC3000 WiFi Module

On the CC3000 shield, I use the following pin connections.

• PIN 1 - GD to Arduino GND
• PIN 2 - VD to Arduino 3.3V
• PIN 3 - CS to Digital 10
• PIN 4 - DO(MISO) to Digital 12
• PIN 5 - DI(MOSI) to Digital 11
• PIN 6 - CK(CLK) to Digital 13
• PIN 7 - IQ(IRQ) to Digital 3
• PIN 8 - EN(VBEN) to Digital 5

Library & Examples code : Adafruit_CC3000 librar

Demo : 

To run the sample sketches, you'll have to edit them to include the SSID and password of your access point.

#define WLAN_SSID     "myNetwork"      // cannot be longer than 32 characters!
#define WLAN_PASS     "myPassword"

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

NOTE: This sketch may cause problems with other sketches
since the .disconnect() function is never called, so the
AP may refuse connection requests from the CC3000 until a
timeout period passes.  This is normal behaviour since
there isn't an obvious moment to disconnect with a server.
