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 is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Bluetooth beacons are hardware transmitters — a class of Bluetooth Low Energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. Bluetooth beacons use Bluetooth Low Energy proximity sensing to ...
iBeacon. 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 Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
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).
For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies. A host operating system can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional profiles to their drivers and stack to enhance what their Bluetooth devices can do.
