You might also like to know how to restore the missing Bluetooth icon from Windows 10/11 taskbar. After downloading and running Bluetooth Version Finder on your PC, select a Bluetooth device from the drop-down box to know the version number. There is a third-party tool called Bluetooth Version Finder around to help you know the Bluetooth version. Method 2 of 2 Use Bluetooth Version Finder to know Bluetooth version As you can see in the screenshot above, my laptop’s Bluetooth LMP is 8.4096 which indicates that the version is 4.2. The LMP versions correspond to Bluetooth versions as follows:įor instance, the Bluetooth adapter’s LMP version 7.x indicates that your Bluetooth version is 4.1. Enhanced Attribute Protocol (EATT), an improved version of Attribute Protocol (ATT). Select the Bluetooth radio listing (yours might simply be listed as a wireless device). The Technical specifications of Latest Bluetooth Version 5.2 over Bluetooth is to add new features viz: 1. Select the arrow next to Bluetooth to expand it. Here, you should see the LMP version (refer to the picture below). To see which Bluetooth version is on your PC In the search box on the taskbar, type device manager, then select it from the results. Right-click on your Bluetooth adapter’s entry and then click Properties. Step 2: In the Device Manager window, expand Bluetooth. Alternatively, type Device Manager in the Start/taskbar search field and then hit Enter key to open the same. Approx.Step 1: Right-click on the Start button on the taskbar and then click Device Manager to open the same. There were deployment issues that kept BT from gaining ground quickly. Improvements to reliability and interoperability mostly backward compatible but not 100%. The type of Bluetooth and profiles may vary, but the core architecture remains the same. Once a secure connection is established between a transmitter and receiver, data is split into small packets, which are then transferred at alternating frequencies. Adaptive frequency hopping (AFH) helped avoid interference with Wi-Fi and other technologies in the same frequency. Plantronics Backbeat Pro 2 Bluetooth operates in the frequency range of (2.402 -2.480GHz). Interference handling was improved, and less power was used.īT 1.2 (Basic Data Rate) was the first widely used Bluetooth technology. Encryption was made mandatory, security was improved, and less power was used.īranded as Bluetooth 2.0 + EDR (Enhanced Data Rate), three bit encoding (versus one) increased the data rate from 1 to 3 Mbps (in practice 2.1 Mbps). Since there was no change in the specification of the Bluetooth A2DP stereo audio profile, the enhancements between the two versions (Bluetooth 4.2 and. Secure Simple Pairing (SSP) was added to make pairing faster and more secure. Introduced low-power Bluetooth Low Energy, branded as "Bluetooth Smart." See Bluetooth LE.īranded as Bluetooth 3.0 + HS (High Speed), it started the connection via Bluetooth but transmitted data over Wi-Fi. ![]() Prior to BT 4.1, devices transmitted to a hub either built into the computer or in a stand-alone dongle. BT 4.1 maintains connections with less manual intervention, and devices can be both client and hub at the same time, enabling Bluetooth devices to communicate with each other. More efficient data exchange and better co-existence with LTE frequencies. ![]() It also supports beacon privacy, which prevents retail shops from sensing a user's presence (see iBeacon). A more robust version with extended battery life, BT 5 increased the outdoor transmission range from 50 to 200 meters. The low-power wireless personal area network (WPAN) version of IPv6 (6LoWPAN) is supported, which enables billions of devices to have a unique IP address. The first smartphones to support BT 5 were the Galaxy S8 and iPhone 8 and X.ĭesigned for the Internet of Things (IoT), BT 4.2 increased the payload size in the Bluetooth packet by 10x, dramatically lowering the overhead to yield 2.5 times more data. Location services are enhanced because it can convey more information prior to establishing a connection. Bluetooth versionsFollowing are the essential features of the various Bluetooth versions.Ī more robust version with extended battery life, BT 5 increased the outdoor transmission range from 50 to 200 meters.
