The document introduces Bluetooth Low Energy (BLE), detailing its specifications and device roles under the Generic Access Profile (GAP) and Generic Attribute Profile (GATT). It covers BLE's low power characteristics, device types such as peripherals and centrals, and provides examples of GATT services and characteristics. The document also briefly mentions the SensorTag and includes contact information for further inquiries.

- 4. Bluetooth LE • Known as Bluetooth Smart, Wibree, Bluetooth ULP • Bluetooth Core Specification version 4.0 • Low power • ~1 year for iBeacon with 900ms advertisement interval on a CR2032 battery • No backward compatibility 4
- 6. GAP GAP - Generic Access Profile • Device roles (Peripheral, Central) 6
- 7. Roles • Central (master, client) • Usually a phone, or computer • Peripheral (slave, server) • Usually a small low power device such as iBeacon or sensor 7
- 8. GAP GAP - Generic Access Profile • Device roles (Peripheral, Central) • Peripheral advertisements • Up to 31 bytes of payload • Multiple receivers • Connections • Transfer much more data • GATT • Exclusive 8
- 10. GATT GATT - Generic Attribute Profile • Requires connection • Services • Characteristics • Properties (e.g. read, write, notify) • Value (max 512 bytes) • Descriptors • Other services 10
