    33 This is primarily used for data sensing, and not for something like streaming audio.
     34This is primarily used for data sensing, and not intended for continuous data-rate applications such as streaming audio or video. This enables new-use cases like beacons and sensors that have low-bandwidth periodic and sporodic data points. This also brings lower power to some use cases such as human interface devices (keyboard and mouse) input that is sporadic in nature, greatly increasing battery life for those devices.

    3536Bluetooth Low Energy is much lower power than classic Bluetooth, possibly lasting months on a coincell. BLE is also cheaper for each peripheral devices.

    3738BLE has many defined profiles, including specific profiles for the healthcare industry, sports and fitness and more. These are all based on the Generic Attribute Profile (GATT).

     40Bluetooth 4.x+ Devices will support Bluetooth Classic (aka BR/EDR) and/or Bluetooth Low Energy. Be away they may not support both and if you have a device that supports 'only' BLE it will not be able to use audio streaming such as the A2DP profile as support for BR/EDR is required for that.
