I've given up on the CC3000, it's just too buggy and problematic.
TI themselves say this on the CC3000 page:
TI recommends CC3200 & CC3100 for all new and existing embedded Wi-Fi & Internet of Things applications.
And they've removed references to the CC3000 on their SimpleLink WiFi page at http://www.ti.com/ww/en/simplelink_embedded_wi-fi/home.html
I'm going to leave these pages here so people searching the web for help don't find dead links, but I recommend you abandon your quest to make this half-baked module work. Best of luck to you.
Version 1.4
Yet another breakout board for the TI CC3000 WiFi module
Based on a design & library by Matt Bigarani, http://www.centerblack.com

The antenna used by Matt from the SparkFun-RF library was the wrong size. SparkFun had one that was close (ANTENNA-CHIP5) but wasn't exactly right so I modified the part in their library. The modified library is included in this project as SparkFun-RF-Modified.lbr
Changes:
- 1.4 - Changed antenna trace from 20 mil to 50 mil & antenna trace gap from 12 mil to 10 mil based on calculations from http://chemandy.com/calculators/coplanar-waveguide-with-ground-calculator.htm
- 1.3 - First board design to be manufactured. Fixed antenna footprint from V1.2
- 1.2 - Fixed antenna gap per antenna datasheet
- 1.1 - Revised BOM to use the same parts as TI whenever possible
- 1.0 - Initial prototype
