Bluetooth LE, Core Bluetooth, and a Glimpse Into Your Near Future

Bluetooth LE is Bluetooth's low power, low latency companion with tons of potential, and it's built into your phone and laptop. Bluetooth LE is cheap, accessible, hackable, and powerful. I'll discuss the current state of Bluetooth LE, why it's awesome, and introduce Core Bluetooth on iOS. Learn how to use it to connect to Bluetooth LE accessories and iOS devices. We'll experiment with dev kits and code and discuss gotchas/limitations of the framework.
