Mark Powell, Executive Director of the Bluetooth Special Interest Group, answers my questions on Bluetooth LE (also known as BLE, also known as Bluetooth 4.0 and 4.1). Bluetooth Smart is Bluetooth LE with an application framework making it easy for applications developers to add support for the more advanced Bluetooth features. Bluetooth.com says it as “Bluetooth Smart products represent a quantum leap for Bluetooth technology, allowing billions of previously disconnected devices to join the connected world.” at http://www.bluetooth.com/Pages/Bluetooth-Smart-Devices.aspx
