Bluetooth is a wireless technology that has been around for over 20 years. Originally developed as a way to connect devices with the intention of building a “mobile phone without wires,” it has now become an integral part of our modern-day culture. Bluetooth has been used to connect everything from keyboards and mice to printers and speakers, providing an easy way to share data from one device to another. Here, are the different versions of Bluetooth that have been released over the years.

Bluetooth® 5.3 ( July 13th, 2021 )
Bluetooth® 5.3, the latest release of one of the world’s most popular wireless IoT technologies, was published July 13th, 2021
Bluetooth 5.2 (January 2020)
Bluetooth 5.2 offers an upgraded version of the original Attribute Protocol (ATT) called Enhanced Attribute Protocol (EATT), which is more efficient and more secure than ATT.
Bluetooth 5 (2016)
A more robust version with extended battery life, BT 5 increased the outdoor transmission range from 50 to 200 meters.
Bluetooth 4.2 (2014)
Designed 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.
Bluetooth 4.1 (2013)
More efficient data exchange and better co-existence with LTE frequencies.
Bluetooth 4 (2010)
Introduced low-power Bluetooth Low Energy, branded as “Bluetooth Smart.” See Bluetooth LE.
