This BLE SDK for iOS provides a framework for Mac OSX and iOS developers to develop Bluetooth 4.0 Low Energy (aka BLE) Apps easily.
It currently supports iOS 7 and Mac OSX 10.9.2.
OSX 10.7.5, 10.8.x and iOS 6 also support BLE but not tested.
OSX 10.9.0 and 10.9.1 have bugs, so we will not support.
For iOS devices, only iPhone 4s/5/5s, iPod touch 5 and iPad 3/4/Air/Mini has BLE 4.0 support.
For Mac devices, if no BLE hardware built-in, you need to buy an USB Bluetooth 4.0 dongle (CSR or Broadcom).
