Bluetooth wireless technology

Bluetooth® wireless technology is the global wireless standard enabling simple, secure connectivity for an expanding range of devices and serves as the backbone for the Internet of Things. Bluetooth® Smart technology, through its updatable platform and low-power consumption, creates new application opportunities for the mobile phone, consumer electronics, PC, automotive, health and fitness, smart home and retail industries. 

Bluetooth® technology is a wireless communications system intended to replace the cables connecting portable and/or fixed electronic devices. Key features of Bluetooth® technology are robustness, low power, and low cost. Many features of the Bluetooth® Core Specification are optional, allowing product differentiation. Bluetooth® Classic is the original version of the technology using the Basic Rate and/or Enhanced Data Rate transport. The low energy feature was introduced in version 4.0 of Bluetooth® technology. A product implementing only this feature is known as a single mode device. A product implementing both Classic and low energy features is known as a dual mode device.

The Bluetooth® core system consists of an RF transceiver, baseband, and protocol stack. The system offers services enabling the connection of devices and the exchange of a variety of classes of data. Many features of the core specification are optional, allowing for flexible product implementations.

Bluetooth Smart

Bluetooth® Smart is a revolutionary technology introduced in 2010, which provided many new benefits to manufacturers, developers and consumers. Bluetooth® Smart is the brand name for the Bluetooth® Low Energy feature first introduced in Bluetooth® Core Specification Version 4.0. 

Bluetooth® Smart goes beyond being simply power-friendly; it is application-friendly too. The technology is power-friendly because it uses dramatically less power than other wireless technologies. It's application-friendly because it costs less and offers flexible development architecture for creating applications for Bluetooth® Smart sensors. This allows developers to bring everyday objects like heart-rate monitors, toothbrushes, and shoes into the connected world and have them communicate with applications that reside on the Bluetooth® Smart compatible smartphones, tablets, or similar devices those consumers already own.
