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
Bluetooth low energy devices can operate in an advertisement mode to notify nearby devices of their presence. [26] In the simplest form, an iBeacon is a Bluetooth low energy device emitting advertisements following a strict format, that being an Apple-defined iBeacon prefix, followed by a variable UUID, and a major, minor pair.

Bluetooth, a short-range wireless system supported by many mobile devices, is one transmission medium used for proximity marketing. The process of Bluetooth-based proximity marketing involves setting up Bluetooth "broadcasting" equipment at a particular location and then sending information which can be text, images, audio or video to Bluetooth enabled devices within range of the broadcast server.
The post then goes on to talk about "discoverable by others," a setting that is connected to the new iOS 17.2 Journal app. ... Journaling Suggestions uses Bluetooth to detect the number of devices ...
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.
For example, Bluetooth MAP is used by HP Send and receive text (SMS) messages from a Palm/HP smartphone to an HP TouchPad tablet. [23] Bluetooth MAP is used by Ford in select SYNC Generation 1-equipped 2011 and 2012 vehicles [24] and also by BMW with many of their iDrive systems. The Lexus LX and GS 2013 models both also support MAP as does the ...
In another example, an attacker sends a file via Bluetooth to a phone within range with Bluetooth in discovery mode. If the recipient accepts, a virus is transmitted. An example of this is a worm called Cabir. [16] The worm searches for nearby phones with Bluetooth in discoverable mode and sends itself to the target device.
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 there is a vulnerability in the vendor's software.
