Bluetooth Low Energy (BLE, aka Bluetooth Smart) is a recent technology.

BLE allows smartphone users to have rich, interactive connections to their surroundings and move their mobile experience beyond the mobile handset.

Bluetooth consumes more power and transmits farther and with more data.It is suited for streaming media such as playing music on Bluetooth speakers or taking a call through a Bluetooth headset. BLE transmits less data over shorter distances using much less power than Bluetooth. BLE is designed for periodic transfers of very small amounts of data, such as beacons providing proximity in a store or a medical device providing glucose measurements to a doctor’s tablet or patient monitor.

Usually the central is what you connect the device to and the peripheral is the device. the central wants data while the peripheral provides them.
