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). It employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz ...
In order to use Bluetooth, a device must be compatible with the subset of Bluetooth profiles (often called services or functions) necessary to use the desired services. A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices.
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] Compared to Classic Bluetooth, Bluetooth Low Energy is ...
The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies. This article gives an overview of the core protocols and those adopted protocols that are widely used. The Bluetooth is split in two parts: a "controller stack" containing the timing ...
A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack. Bluetooth stacks can be roughly divided into two distinct categories: General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers. Support for additional Bluetooth profiles can typically be added through drivers. Embedded system ...
BlueSoleil is a Bluetooth software/driver for Microsoft Windows, Linux and Windows CE. It supports Bluetooth chipsets from CSR, Broadcom, Marvell etc. Bluetooth dongles, PCs, Laptops, PDAs, PNDs and UMPCs are sometimes bundled with a version of this software albeit with limited functionality and OEM licensing. The software is rarely needed on modern computers, as well-functioning Bluetooth ...
Fast Pair. The Google Fast Pair Service, or simply Fast Pair, is Google 's proprietary standard for quickly pairing Bluetooth devices when they come in close proximity for the first time using Bluetooth Low Energy (BLE). [1] It was announced in October 2017 and initially designed for connecting audio devices such as speakers, headphones and car ...
With the help of a Bluetooth beacon, a smartphone's software can approximately find its relative location to a Bluetooth beacon in a store. Brick and mortar retail stores use the beacons for mobile commerce, offering customers special deals through mobile marketing, [6] and can enable mobile payments through point of sale systems.
