Kyle Gordon purchased a CC3000 module from EBay and found that it wasn’t completely compatible with the Arduino library available from Adafruit. The problem arose from the module having an earlier firmware version. So Kyle devised a method using two Arduino Pro Minis to load updated firmware to the CC3000.
For more details, you can find the post on The Lodge blog.

I think I should clarify – I only needed a second Pro Mini in order to update the bootloader on the other one, in order to allow the full CC3000Patch sketch to be uploaded.
A regular single Pro Mini will run the CC3000Patch sketch without a problem – if it has a recent Optiboot bootloader installed :-)
