2.1 devices feature Secure Simple Pairing (SSP): this not only improves the pairing experience, but increases the use and strength of security. The 2.1 version makes it easier to pair with devices from different manufacturers and increases the reliability of the pairing process. Devices with basic rate + EDR (optional) have theoretical maximum data rate of 3 Mbps.

Bluetooth 2.x introduces the optional Enhanced Data Rate (EDR) capability. Those are relic devices that are nearly extinct, useful as collectors items :) Bluetooth 2.x - Basic rate + EDR (optional) The most popular variant, especially 2.1. In addition to the versions, there are some specific optional features and differences explained in detail below: Bluetooth 1.x - Basic rate bluetooth Bluetooth 1.x has theoretical max data rate of 1Mbps. If given an option, always choose the device with the highest Bluetooth version. Given that by 2035, it is predicted that around 14.2 million (opens in new tab) adults will have hearing loss greater than 25 dBHL across the UK, this is welcome news indeed.In general, each revision of Bluetooth improves upon power consumption, data rate, security, pairing reliability, ease and speed, etc. “Auracast broadcast audio is well positioned to become an advanced, new assistive listening system that will be significantly easier and lower cost to deploy, while offering higher audio quality and greater privacy, improving audio accessibility and promoting better living through better hearing.” “While current assistive listening systems, such as inductive loops, have been providing great benefit to people with hearing loss, they suffer from a number of challenges that have limited their deployment, including poor quality, high cost, and lack of privacy,” said Nick Hunn, CTO of WiFore. Essential flight announcements, gate changes, boarding schedules and other travel information can be accessed directly on your personal audio device from the airport's public address system.
Soon, they will be able to broadcast audio that any visitor with Auracast-enabled Bluetooth earbuds or hearing aids can access. Think of those silent TVs in public venues such as airports, gyms and waiting rooms.

Of course, Auracast will allow us all to invite a friend to enjoy our curated playlist without having to sacrifice one of our own earbuds (as long as they've brought theirs), but we will also be able to enjoy TV in public spaces. “The launch of Auracast broadcast audio will trigger another massive change in the wireless audio market," said Mark Powell, CEO of Bluetooth SIG, adding, "The ability to broadcast and share audio using Bluetooth technology will reshape personal audio and enable public venues and spaces to deliver audio experiences that will improve visitor satisfaction and increase accessibility."Ĭertainly, for hearing aid wearers, the implications are huge here – life-changing even. Analysis: Auracast is huge, just consider the implications In that respect, the UI is similar to how scanning for and associating with Wi-Fi networks has worked, where there is support within the underlying OS platform as well as third party apps that can be used."Įssentially then, Auracast needs Bluetooth 5.2 to work, and phones will need to be updated so you can find and choose Auracast broadcasts. "The UI on a smartphone that is used to identify and select an Auracast broadcast to join can be part of the device operating system as well as part of an app like one that comes with earbuds. So, say someone wants to join an Auracast broadcast that is transmitting from someone else's phone: will the the user interface (the one they will find and select the broadcast from) the phone their earbuds are normally connected to, and the earbuds will then switch to the Auracast connection? "Technically, for a receiver, or any product, to support Auracast broadcast audio it must support specific features that were introduced in version 5.2 of the Bluetooth Core Specification as well as the Public Broadcast Profile within the set of LE Audio specifications."
