title: How can I check for hardware BLE support on OS X?
body: <p>I've read <a href="http://appleinsider.com/articles/11/07/20/apple_adds_bluetooth_4_0_support_to_new_macbook_air_mac_mini.html">here</a> that Apple computers from mid-2011 should support BLE (Bluetooth Low Energy). Is there a way (perhaps using the command line) to check if the device and the operating system supports BLE?</p>
