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 compliant architecture shares all of Classic Bluetooth's existing radio and functionality resulting in a negligible cost increase compared to Classic Bluetooth. Cost-reduced single-mode chips, which enable highly integrated and compact devices, feature a lightweight Link Layer providing ultra-low power idle mode operation, simple device ...
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.
Bluetooth 2.1 improved device pairing speed and security. Bluetooth 3.0 again improved transfer speed up to 24 Mbit/s. In 2010 Bluetooth 4.0 (Low Energy) was released with its main focus being reduced power consumption. Before Bluetooth 4.0 the majority of connections using Bluetooth were two way, both devices listen and talk to each other.
The post then goes on to talk about "discoverable by others," a setting that is connected to the new iOS 17.2 Journal app. ... users can choose to enable secondary authentication, and lock the ...
These tools, available on the dark web or developed by hackers, enable attackers to access sensitive information from compromised devices. [ 3 ] Any device with its Bluetooth connection turned on and set to "discoverable" (able to be found by other Bluetooth devices in range) may be susceptible to Bluejacking and possibly to Bluesnarfing if ...
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.

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 ...
