Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries. [4]
Bluetooth Mesh is a computer mesh networking standard based on Bluetooth Low Energy that allows for many-to-many communication over Bluetooth radio. The Bluetooth Mesh specifications were defined in the Mesh Profile [ 1 ] and Mesh Model [ 2 ] specifications by the Bluetooth Special Interest Group (Bluetooth SIG).
In Windows 7, Bluetooth device settings have been moved to Devices and Printers from the Control Panel applet. Windows 8 expands its Bluetooth stack with support for Bluetooth 4.0 which includes Bluetooth Low Energy (BLE). [28] Windows 8.1 added developer APIs for Bluetooth Low Energy (GATT) and RFCOMM.
Compared to regular Bluetooth Audio, Bluetooth Low Energy Audio makes lower battery consumption possible and creates a standardized way of transmitting audio over BT LE. Bluetooth LE Audio also allows one-to-many and many-to-one transmission, allowing multiple receivers from one source or one receiver for multiple sources, known as Auracast.
The Bluetooth asynchronous connection-oriented logical transport (ACL) is one of two types of logical transport defined in the Bluetooth Core Specification, either BR/EDR ACL or LE ACL. BR/EDR ACL is the ACL logical transport variant used with Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR, also known as Bluetooth Classic) whilst LE ACL is the ...
The Bluetooth protocol stack is split in two parts: a "controller stack" containing the timing critical radio interface, and a "host stack" dealing with high level data. The controller stack is generally implemented in a low cost silicon device containing the Bluetooth radio and a microprocessor.
Smartphone detecting an iBeacon transmitter. iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013. [1] Various vendors have since made iBeacon-compatible hardware transmitters – typically called beacons – a class of Bluetooth Low Energy (BLE) devices that broadcast their identifier to nearby portable electronic devices.
The way a device uses Bluetooth depends on its profile capabilities. The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner. For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies.
