Don't pay for features you can't use

Bluetooth was once a new, strange, and advanced wireless technology. For those of us who remember using the IR port on our very dumb phones, Bluetooth seemed like witchcraft. Today, almost everything uses BT, and it has become a reliable, seamless part of our lives.

This is largely due to the constant improvements that have been made to the original release. At the time of writing, Bluetooth 5.1 has been announced.

Each version brings new features and improvements. All versions are also backwards compatible, but you are generally limited to the features supported by the lowest BT version hardware in use.
