Bluetooth® 5 Arrives in Smartphones, Improving the Connections You Know and Love.

Bluetooth 5

Today, a mere five months after we formally adopted Bluetooth 5, the Samsung Galaxy S8 became the first smartphone to ship to consumers using the technology. To learn more, we recommend reading Computer Weekly's David McClelland’s great assessment of Bluetooth 5, its benefits, and what’s next, based on an interview with our own Steve Hegenderfer. So, what is next? Before we talk about where we are going, let’s talk about where we’ve been. Since its inception, Bluetooth technology has been in the... Continue Reading

Plotting the Future

At CES, it’s always fun to see the huge variety of products dreamed up by forward-thinking inventors whose imaginations know no bounds. Knowing this limitless creative spirit is possible in part because of Bluetooth—well, that’s a good feeling, too. Plott is translating the freedom of the IoT to devices that simplify complicated tasks. Their Cubit and Miletus devices combine smart measurement and calculation with Bluetooth connectivity and display so users can visualize changes they want to make... Continue Reading

Bluetooth Pairing Part 5, Legacy Pairing – Out of Band

Bluetooth Pairing Part 5, Legacy Pairing – Out of Band

In previous blogs, we touched on topics such as Passkey Entry and Numeric Comparison which are two types of pairing methods. Today, I will introduce another one, out of band. The out of band (OOB) association model is designed for scenarios where an out of band mechanism is used to both discover the devices as well as to exchange or transfer cryptographic information which would be used in the pairing process. Out of band is a flexible option for developers that allows you to define some of your... Continue Reading

That’s A Wrap, Bluetooth World 2017

Bluetooth World 2017 show floor

Last week in Santa Clara, California, Bluetooth World was host to more than 1,100 developers, executives, and start-ups. This year's conference showcased how Bluetooth technology is rapidly evolving to meeting IoT needs, and what we can expect in the near and distant future. Developers were able to gain hands-on experience building the devices that will change the way we interact with technology in our everyday lives. You can check out #BluetoothWorld on Facebook, Twitter, and Instagram to get more... Continue Reading

Meet the Imagine Blue Winner - Sara Du

Fortunately, not many young teenagers get stranded in the wilderness; fewer still come back inspired to use technology to prevent it from happening to anyone else. But that's what happened to Sara Du, the winner of this year's Student category for the Imagine Blue awards and creator of the Bluejay device. Sara wound up stranded due to a technology failure. "A few years ago, I volunteered at an event," she explains, "in this little valley between the mountains…After the event, everybody started to... Continue Reading

Meet the Bluetooth Pioneer: Kento Sasamoto

The Internet of Things (IoT) is making our lives easier in many ways, connecting the devices and objects we use daily so that our worlds function more smoothly. There are many ways we can control those connected devices, from computers to smartphones, but those methods can have their limitations—for anyone, but especially for people with various disabilities. Enter the MagicKnock: a device that allows one to control connected devices with a simple knocking sound that can be made with fingertips, Continue Reading

Exploring Bluetooth 5 - What's new in Advertising?

Bluetooth 5

Staring at the P-51 Mustang, you ponder its history.... Dangerous missions escorting bombers, dogfights, battles with the Luftwaffe.... Turning your head, you see a Curtis P-40 across the way. As you walk over to take a closer look, you hear an unsettling whistle followed by the roar of a radial engine. Looking up you see a gull winged Corsair hanging in mid-dive. Feeling a thump on your wrist, you read “Air driving across the engine air inlets at high speed produced an eerie whistle. The Corsair... Continue Reading

Exploring Bluetooth 5 - How Fast Can It Be?

Bluetooth 5 is here and it’s a major step up from the current standard for wireless connectivity, Bluetooth v4.2, with its 4-times longer range, 2-times higher speed, plus 8-times larger advertisement packet length for data. Developers can visit the Bluetooth SIG website and download the latest Bluetooth core spec here. Right after Bluetooth 5 was released, a developer asked me, “with the higher bandwidth feature, how fast can Bluetooth 5 be?” Today, we will have an inside look at Bluetooth low... Continue Reading

Bluetooth Low Energy - It starts with Advertising

Bluetooth is all around us:  electronic beacons guiding firefighters through buildings; wearable medical devices sending patient’s biological data to a physician’s tablets; manufacturing equipment monitoring in 400,000 square foot warehouses; and more.  Bluetooth technology is growing and is expected to have an install base of over 48 billion by 2021 (per ABI Internet of Everything Market Tracker). So how does Bluetooth work?  Bluetooth low energy has 40 physical channels in the 2.4GHz ISM band, Continue Reading

Exploring Bluetooth 5 - Going the Distance

Bluetooth 5

The Age of IoT According to a paper by Goldman Sachs, in the 1990s there were approximately 1 billion devices connected to the internet. In the 2000s, the “age of the smartphone”, this figure rose to 2 billion. ABI Research now forecast that by 2021 there will be 48 billion devices connected to the internet, in what we’re likely to term “the age of IoT”. Of those 48 billion devices, 30% are forecast to be Bluetooth devices. This is no coincidence. Bluetooth low energy has been actively developed... Continue Reading
