Some form of DoS is also possible, even in modern devices, by sending unsolicited pairing requests in rapid succession; this becomes disruptive because most systems display a full screen notification for every connection request, interrupting every other activity, especially on less powerful devices. The Bluetooth Innovation World Cup, a marketing initiative of the Bluetooth Special Interest Group (SIG), was an international competition that encouraged the development of innovations for applications leveraging Bluetooth technology in sports, fitness and health care products. The competition aimed to stimulate new markets. [159]Kardach, Jim. "The Naming of a Technology". kardach.com. Archived from the original on 22 October 2021 . Retrieved 22 October 2021. Passkey Entry: This method may be used between a device with a display and a device with numeric keypad entry (such as a keyboard), or two devices with numeric keypad entry. In the first case, the display presents a 6-digit numeric code to the user, who then enters the code on the keypad. In the second case, the user of each device enters the same 6-digit number. Both of these cases provide MITM protection. Muller, Nathan J. (2002). Networking A to Z. McGraw-Hill Professional. pp.45–47. ISBN 9780071429139. Archived from the original on 24 June 2021 .

This method is typically used by headsets with minimal IO capabilities, and is more secure than the fixed PIN mechanism this limited set of devices uses for legacy pairing. This method provides no man-in-the-middle (MITM) protection.

Another major advantage of Bluetooth 5.0 is that it simultaneously enables two devices to pair with a third device. Imagine this scenario: there are two people with their wireless headphones listening to the same music from the same smartphone or controlling the speakers in your bathroom as well as your kitchen with just one phone. As you know, Bluetooth version 5.0 specifications were refined for the Internet of Things. That means the new version of Bluetooth was designed to use less power on each device than version 4.0. For instance, all audio devices communicate over BLE, and you can switch on your Bluetooth for a more extended period without worrying about the battery running out.

Enhanced Retransmission Mode (ERTM) This mode is an improved version of the original retransmission mode. This mode provides a reliable L2CAP channel. Streaming Mode (SM) This is a very simple mode, with no retransmission or flow control. This mode provides an unreliable L2CAP channel. Announced in January 2020, LE Audio allows the protocol to carry sound and add features such as one set of headphones connecting to multiple audio sources or multiple headphones connecting to one source [29] [30] and also adds support for hearing aids. [31] It introduces LC3 as its default codec. [32] Compared with standard Bluetooth audio it offers longer battery life. [32] Redmondpie". 3 December 2014.

With the May 2016 Bluetooth SIG branding information, the Bluetooth SIG began phasing out the Bluetooth Smart and Bluetooth Smart Ready logos and word marks and reverted to using the Bluetooth logo and word mark [8] in a new blue colour. The technology has undoubtedly evolved from connecting PC ancillary systems into a domestic IoT connectivity solution. Let us study some compelling use cases of Bluetooth.

The Service Discovery Protocol (SDP) allows a device to discover services offered by other devices, and their associated parameters. For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them. Each service is identified by a Universally Unique Identifier (UUID), with official services (Bluetooth profiles) assigned a short form UUID (16 bits rather than the full 128).

Bluetooth Core Specification version 2.1 + EDR was adopted by the Bluetooth SIG on 26 July 2007. [80] In January 2005, a mobile malware worm known as Lasco surfaced. The worm began targeting mobile phones using Symbian OS ( Series 60 platform) using Bluetooth enabled devices to replicate itself and spread to other devices. The worm is self-installing and begins once the mobile user approves the transfer of the file (Velasco.sis) from another device. Once installed, the worm begins looking for other Bluetooth enabled devices to infect. Additionally, the worm infects other .SISfiles on the device, allowing replication to another device through the use of removable media ( Secure Digital, CompactFlash, etc.). The worm can render the mobile device unstable. [142] Brand Enforcement Program". Bluetooth.com. Archived from the original on 20 February 2018 . Retrieved 8 May 2019.
