Full list of Bluetooth versions in 2022 (Updated!)

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.
