Bluetooth 6.1 is here to make your devices smarter, safer, and a lot harder to track

Bluetooth has always been the quiet genius behind our favourite gadgets, invisibly syncing headphones, watches, speakers, and more. But behind that seamless connection, there’s been a growing problem: privacy. The kind of privacy that’s harder to spot but easier to exploit. Now, with the arrival of Bluetooth 6.1, the folks at the Bluetooth Special Interest Group (SIG) are trying to fix that, and maybe even reshape how our devices protect us in the background.

Bluetooth 6.1 makes devices a lot harder to track

Let’s start with the privacy stuff. Bluetooth 6, released last year, added the ability to randomise your device’s MAC address every 15 minutes using a clever trick called a Resolvable Private Address (RPA). That’s like wearing a new disguise every quarter-hour. But the problem? It was on a timer that made it predictable, and still trackable if someone was persistent enough.

Enter Bluetooth 6.1. Instead of fixed 15-minute changes, the new protocol randomises the RPA every eight to 15 minutes, unpredictably. That unpredictability makes it a nightmare for would-be trackers. You’re now harder to follow in a crowd of connected gadgets.

What’s even better is that these randomisations are now handled directly by the Bluetooth controller, not your device’s processor. Which means less strain on your battery, especially in smaller devices like TWS earbuds, fitness trackers, and smartwatches. More privacy, less power drain.

Bluetooth SIG has also moved to a twice-a-year update cycle, so we might see Bluetooth 6.2 by late 2025. But for now, Bluetooth 6.1 isn’t just a spec bump, rather, it can be called a thoughtful evolution. One that quietly retools your tech to be more private, more efficient, and just a little bit smarter about the invisible dance it does every day. 

As our world leans ever harder on wireless everything, communication standards aren’t just about speed or convenience anymore, they’re about trust. With Bluetooth 6.1, the protocol that once just connected our gadgets is starting to look more like a guardian. And in a world where privacy is becoming the next big frontier, that shift couldn’t come soon enough.
