Make sure the power connection is solid & any wires or connectors properly soldered in. Do not try to 'press fit' or 'twist' wires onto the power pins without soldering, as it will not work well and cause a lot of difficulty with pairing and usage.
You'll also need to make sure that your computer that you'll be pairing with has Bluetooth v2.1 or great hardware installed. Nearly every Mac computer/laptop, Windows laptop and Android tablet has this already. If not, a USB Bluetooth module such as this one is ideal. Watch out for "cheap $5" bluetooth USB modules, they are often v2.0 only, and won't work with Bluefruit due to the advanced firmware requirements.
It is not possible to pair the EZ-Link with iOS devices such as iPhones or iPads - Apple does not permit 'SSP' pairing! Check out the EZ-Key for a iOS compatible bluetooth keyboard module you may be able to use.
That's it, you're now paired!

Next you can figure out the name of the device by opening up a Terminal and typing in ls /dev/cu.* and looking for something like /dev/cu.AdafruitEZLinkxxxx-SPP
