I bought a CC3000 Wifi Shield from Sparkfun and attached it to Arduino Uno board.

As first thing I tested the board with the board test example:

SparkFun CC3000 - Board Test

CC3000 initialization complete

Firmware version: 1.24

MAC address: 70:FF:76:01:30:1E

Finished board test


Then I scanned the networks:

SparkFun CC3000 - Scan Test

CC3000 initialization complete

Scanning APs. Waiting for scan to complete.

Access Points found:

SSID: dnhm MAC address: 20:AA:4B:08:AA:CC RSSI: 58 Security: WPA2

SSID: dnhm-guest MAC address: 20:AA:4B:08:AA:CE RSSI: 58 Security: Unsecured

Finished scan test


I set the SSID and the password and tried to connect:

SparkFun CC3000 - Connection Test

CC3000 initialization complete

Connecting to: dnhm

Error: Could not connect to AP

Error: Could not obtain connection details

Error: Could not disconnect from network Finished connection test


SparkFun CC3000 - Connection Test

CC3000 initialization complete Connecting to: dnhm-guest

Error: Could not connect to AP

Error: Could not obtain connection details

Error: Could not disconnect from network

Finished connection test

It did not connect none of the available connections, I reserved an IP address on the router for the mac address, but nothing changed.

I turned on logs on the router (Linksys e2500) and nothing appeared in logs as if the device never tried to connect. (I can see relevant logs when I re-connect with my notebook)

I use wpa2 so I kept the security setting as it is. I also have a 5ghz SSID and it does not show up in the scan. So I did not try to connect to it.

I also tried the smart config example with my ipad and it did not work either, the output:

SparkFun CC3000 - SmartConfig

CC3000 initialization complete

Starting SmartConfig

Send connection details from app now!

Waiting to connect…

Error: Could not connect with SmartConfig

Error: Could not obtain connection details

Looking up IP address of: www.sparkfun.com

Error: Could not lookup host by name

Pinging 0.0.0.0 3 times…

Error: no ping response

Error: Could not disconnect from network

Finished SmartConfig test

Obviously the board works (It can scan/find the networks), but cant connect them. What should I do as next step to troubleshoot the issue?

Here is the sample I used for connection testing: (I double checked the protocol from router's wifi settings to make sure I'm using the correct one)

Connects to the access point given by the SSID and password and
waits for a DHCP-assigned IP address. To use a static IP
address, change the #define USE_DHCP from 1 to 0 and assign an
IP address to static_ip_addr in the Constants section.

NOTE: Static IP is not working at this time.

The security mode is defined by one of the following:
WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA, WLAN_SEC_WPA2

Hardware Connections:

 Uno Pin    CC3000 Board    Function

 +5V        VCC or +5V      5V
 GND        GND             GND
 2          INT             Interrupt
 7          EN              WiFi Enable
 10         CS              SPI Chip Select
 11         MOSI            SPI MOSI
 12         MISO            SPI MISO
 13         SCK             SPI Clock

Resources:
Include SPI.h and SFE_CC3000.h

Development environment specifics:
Written in Arduino 1.0.5
Tested with Arduino UNO R3

This question came from our site for electronics and electrical engineering professionals, students, and enthusiasts.

    
Could you share your sketch code? Also, are you setting the proper security mode, for the Connection Test Examples? – Cloudedturtle Jan 27 '15 at 13:40
    
I added the source code into the question, it s the sample that comes with the library. I just replaced SSID and the password. I also checked & verified the security mode from router settings. – dvdmn Jan 28 '15 at 0:02
