d) Bluetooth 4.0īluetooth version 4.0 was released in 2010. Its high rate of power consumption has significant drawbacks. Bluetooth version 3.0 comes with other new specifications such as Ultra-wideband, Enhanced Power Control, L2CAP Enhanced modes, Unicast Connectionless Data, and Alternate MAC/PHY. Over a collocated 802.11 link, Bluetooth 3.0 through the High Speed (HS) mode enables the transfer of data with speeds of up to 24 Mbps. This Bluetooth version was announced on the market in 2009. It enhanced the pairing experience, security, and extended inquiry response (EIR), thus allowing improved devices’ filtering before establishing a connection. The technology improved further after the launch of Bluetooth version 2.1 by supporting a new feature dubbed “simple, secure pairing” (SSP). The role of GFSK is to improve the speed of data transfer by supporting the Enhanced Data Rate (EDR). GFSK and phase-shift keying modulation (PSK) are some of the main improved features in this version. This version of 2.0 was released in 2004. Significant improvements included sustenance for adaptive frequency-hopping spread spectrum (AFH) that minimized interference, quicker speed transmissions of close to 721kbit/s, Host Controller Interface (HCI), improved discovery, and Extended Synchronous Connections (ESCO). Some of the minor challenges were fixed by Bluetooth version 1.1, but the most significant problems were fixed after Bluetooth version 1.2. As the technology was somehow immature, challenges such as no anonymity were encountered, but the technology is now outmoded by today’s standards. It was invented in 1998 and was a significant groundbreaking discovery. Let’s dive into the Bluetooth version history and discover the progress made from Bluetooth 1.0 to Bluetooth 5.2. From Bluetooth 1.0 to the latest Bluetooth 5.2, each version has brought significant advancements and new features to the world of wireless connectivity. Specifications and features from Bluetooth 1.0 to Bluetooth 5.0īluetooth technology has come a long way since its inception in 1998. Even though its maximum data output is 1Mbps, BLE is still unsuitable for products that need continuous data streaming. It was geared towards installing applications that require low power consumption and a GFSK modulation scheme that would enable it to return insufficient data output of 1Mbps. Bluetooth Low Energy: Versions 4.0 – 5.0īluetooth 4.0 was announced to the marketplace forming a new grouping named Bluetooth Low Energy (BLE). The first Bluetooth version’s release paved the way for the emergence of wireless items such as speakers, headphones, Bluetooth beacons, and game controllers used today. Data packets used and modulation schemes are the primary determinants of these factors. They are power consumption, range, and data speed. We have 3 factors that enable someone to distinguish the different Bluetooth versions. Their connection range and stability are great, more energy-effective, and offer improved security than older Bluetooth versions.
BLUETOOTH VERSIONS UPDATE
This article will explore the difference between Bluetooth versions, the specifications of different Bluetooth versions, ranges of Bluetooth devices by class, and reasons you should update your Bluetooth to version 5.2.īluetooth versions’ main differences are that the most recent Bluetooth versions provide a high data transfer speed. The latest versions have great additional features that are unsupported by older versions. If you find out that your device doesn’t have a specific version with a required feature, you can always get an inexpensive USB Bluetooth adapter from Amazon.Do you know that it took more than 15 years since the introduction of Bluetooth technology for Bluetooth 5.0 to emerge? Bluetooth is found in almost every device, from smartphones and smartwatches to wireless headsets and wireless mice. Once you complete the steps, you will know the adapter version you have on your computer. In this case, the LMP has the #4, so the version is “Bluetooth 2.1 + EDR.” Here’s a table with the available Link Manager Protocol versions, which you can use to confirm the actual Bluetooth version: LMP
