Big Steps Forward for Bluetooth LE

Bluetooth LE (Low Energy) was publicly introduced into the Bluetooth core specification version 4.0 in June 2010. Over the last 11 years, Bluetooth LE has developed massively in popularity, forming the basis for a huge network of smart devices. True to its original intention, Bluetooth LE enables billions of smart devices around the world to share data, enable wireless control, and create the low power wireless applications that enable the internet of things.

Bluetooth LE has changed dramatically since it was first introduced. Initially designed only with ultra-lightweight use cases in mind, Bluetooth LE has expanded in complexity, scope, throughput capability, and security. And now in the 5.2 specification, it adds a completely new use case (LE Audio) to its list of capabilities, as well as new changes to power control, attribute protocols, and multi-channel transmission.

In this post we’ll look at the three major changes to the Bluetooth specification introduced in Bluetooth 5.2, namely LE Audio, Enhanced Attribute Protocol (EATT), and LE Power Control.
