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.
iBeacon is based on Bluetooth low energy proximity sensing by transmitting a universally unique identifier [4] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [5] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
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.
It can also be used to Bluetooth connect audio to pretty much any device with a standard 3.5 millimeter headphone jack. Use it on airplanes to connect AirPods to in-flight entertainment, at gyms ...
A Bluetooth WPAN is also called a piconet, and is composed of up to 8 active devices in a master-slave relationship (a very large number of additional devices can be connected in "parked" mode). The first Bluetooth device in the piconet is the master, and all other devices are slaves that communicate with the master.
The Apple A11 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, [6] and manufactured by TSMC. [1] It first appeared in the iPhone 8 and 8 Plus, and iPhone X which were introduced on September 12, 2017. [6] Apple states that the two high-performance cores are 25% faster than the Apple A10 's and the four high-efficiency cores are up to ...
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 ...
The Bluetooth 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. The host stack is generally implemented as part of an operating system, or as an installable package on top of an ...
