![]() Wideband speech from improvements to the audio architecture.services for wireless coexistence on mobile devices.Minor duty cycle-based public relations.This version also supports the following additional new features: Because BLE devices are powered by coin-cell batteries, power consumption has increased significantly. Back then, the version was advertised as Bluetooth Smart and Wibree, even though it still supported all of the previous versions’ functions. Bluetooth 4 Bluetooth 4.0īluetooth 4.0 was introduced in 2010. ![]() Its high power consumption rate has considerable drawbacks. Other new Bluetooth 3.0 requirements include Ultra-wideband, Enhanced Power Control, L2CAP Enhanced modes, Unicast Connectionless Data, and Alternate MAC/PHY. Bluetooth 3.0 High Speed (HS) mode allows data transfer at speeds of up to 24 Mbps over a collocated 802.11 link. ![]() This Bluetooth model was introduced to the market in 2009. It improved security, extended inquiry response (EIR), and pairing functionality, enabling better device filtering prior to connection. GFSK’s function is to accelerate data transfer by supporting the Enhanced Data Rate (EDR).Īfter the release of Bluetooth version 2.1, the technology advanced even more by supporting a brand-new feature called “simple, secure pairing” (SSP). Some of the main enhancements in this version include GFSK and phase-shift keying modulation (PSK). In 2004, this version 2.0 was made public. It has an Adaptive Frequency Hoping function that stopped Bluetooth from interfering with other wireless technologies like WiFi. The most popular version of Bluetooth, Bluetooth 1.2, came along in 2003 with faster pairing times. This just indicated that a new version would be released soon. Interoperability, dependability, and backward compatibility were all enhanced, though not entirely. Two years later, in 2001, Bluetooth 1.1 replaced the prior version. Another version of Bluetooth 1.1 was subsequently released as a result of this. However, because of deployment problems, it did not become as well-known as quickly. With its initial specifications, this was seen in 1999. ![]() The first Bluetooth version ever created was Bluetooth 1.0. ![]()
