What’s New in Bluetooth 5.1?
In a Wave of New Devices, Bluetooth 5.1 is Arriving
Since Bluetooth’s infancy in 1999, Bluetooth’s scope and feature set have grown dramatically, from a focus on wireless headsets to ubiquity in all short-range wireless devices and applications. And with subsequent specification releases, Bluetooth has transformed to allow intermittent sensor connections, much longer range, and a world of new use cases that were never originally dreamed possible. Every new iteration of Bluetooth has made it stronger, more useful, and ultimately more appealing, contributing to its near universal adoption in wireless applications.
Bluetooth 5.1, the second-most recent standard, was presented by the Bluetooth SIG on January 21, 2019, and has made its way into available Bluetooth hardware. It introduces several fixes, enhancements, and new features. In our premiere episode of the Connectivity Corner podcast, our hosts Bob, Rikki, Jennifer and Mahendra talked through some of these new Bluetooth 5.1 features and their implications. These updates improve connection speed and performance, but also create a brand new use cases for location and tracking.
We’ll look today at a few of the most critical new features in Bluetooth 5.1, which include AoA / AoD , advanced GATT caching, and changes to channel advertising.
