BLE

aid: ble
name: BLE
description: Bluetooth Low Energy (BLE), also known as Bluetooth Smart, is a wireless personal area network technology designed
  and marketed by the Bluetooth Special Interest Group (Bluetooth SIG). Aimed at IoT and embedded applications, BLE provides
  reduced power consumption while maintaining similar communication range to classic Bluetooth. The specification is managed
  by the Bluetooth SIG and covers the full protocol stack including the Generic Attribute Profile (GATT), Generic Access Profile
  (GAP), and the various service and characteristic specifications used for device interoperability.

  name: GATT and Assigned Numbers
  description: The Generic Attribute Profile (GATT) defines the framework for data transfer between Bluetooth LE devices.
    The Bluetooth SIG maintains assigned numbers for services, characteristics, and descriptors that enable interoperable
    implementations. GATT services include Battery Service, Heart Rate, Device Information, Health Thermometer, and many other
    standardized profiles.
