Bluetooth Core 6.1: Advanced Wireless with Enhanced Privacy

Bluetooth is the technology that lets devices like phones, headphones, and smartwatches connect wirelessly. A new version called Bluetooth Core 6.1 was released on May 6, 2025. This version brings important changes that help make Bluetooth safer and use less battery. In this post from the Orcacore website, we’ll explain everything in simple terms so you can understand what Bluetooth Core 6.1 means and why it matters.

Why the Bi-Annual Release Cycle Matters?

In the past, new Bluetooth updates came slowly. Now, Bluetooth has moved to a schedule where updates come twice a year (every six months). This means new features and fixes will be available faster.

This is great news for developers who build apps and devices, companies that make products, and people who use Bluetooth every day.

Alain Michaud, a leader from the Bluetooth SIG group, said:

“Moving to a bi-annual release cycle for the Bluetooth® Core Specification represents a pivotal step forward for the entire Bluetooth technology ecosystem.”

What’s New in Bluetooth Core 6.1?

The most exciting feature in this update is called Randomized RPA Updates. Let’s break it down:

Better Privacy:

Devices that use Bluetooth send out addresses, kind of like a name tag. Before, these addresses could be guessed or tracked. Now, Bluetooth changes these addresses at random times. This makes it much harder for someone to follow or spy on your device.

Saves Battery Life:

Before, your phone or device had to handle changing these addresses. Now, the small Bluetooth chip (called the “Controller“) does it instead. This helps your battery last longer, especially on small devices like earbuds or smartwatches.

Enhanced Communication with Bluetooth 6.1

Bluetooth Core 6.1 also comes with a new section in the guide that helps developers and companies. This section explains Bluetooth features using simple words and helps everyone talk about Bluetooth in the same way. It’s a helpful tool for companies to clearly explain what Bluetooth can do in their products.

Best Practices for Product Messaging

The group that manages Bluetooth (Bluetooth SIG) says companies should not advertise their products by using version numbers like “Bluetooth 6.1.” Instead, they should talk about the features that people care about, like:

• Longer battery life
• Better security and privacy
• Stronger connections
• Easy and fast pairing

This helps customers understand what the product offers without needing to know technical version numbers.

The Impact on the Bluetooth Ecosystem

Bluetooth Core 6.1 helps improve wireless technology for everyone. Whether you’re using Bluetooth at home, at work, or on the go, the changes in this update make it more secure, more energy-saving, and more useful.

Devices like smart home gadgets, fitness trackers, Wireless speakers, medical wearables, and more, all will benefit from this update.

Here’s a quick table showing the new features in Bluetooth 6.1 and what they do:

Feature	What it means
Randomized RPA Updates	Makes it harder to track your device, better privacy
Controller-side Address Management	Bluetooth chip handles updates, saves battery life
New Guide Section for Developers	Easier to explain Bluetooth features to users and customers
Bi-Annual Release Schedule	New updates come faster – better features sooner

Conclusion

Bluetooth Core 6.1 is a big step forward for wireless technology. It helps protect your privacy, makes batteries last longer, and gives developers better tools to build great products. Thanks to the new release schedule, we’ll see more improvements like this more often.

Whether you’re using Bluetooth to listen to music, track your health, or control smart devices, these changes will help your devices work better and more safely.

Bluetooth is getting smarter, faster, and more helpful, and this is just the beginning.
