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

Meet the Bluetooth Pioneer: Celia Garrido-Hidalgo

"As long as I remember, I've always been amazed by the complexity of industrial processes, trying to discover which is the secret behind automation systems and industrial robots." So says Celia Garrido-Hidalgo, 23, who's quickly making a name for herself by innovating in the industrial space and was most recently named a student finalist in the Imagine Blue awards program. When Celia visited factories as part of her education, she says she "could feel how operators risk their lives by exposing themselves... Continue Reading

Now That’s a Fish Story

The Internet of Things extends further every day—almost anywhere imaginable. Now, it extends to your favorite fishing hole, too. At CES this year, as we delved into the new and exciting ways Bluetooth technology is being used to make the world a more connected place, we chatted with Nic Wilson, Co-Founder and CEO of Anglr Labs. Nic is a fisherman, and after a friendly argument about how many fish he and his friends had caught one day, he was inspired to develop a technology-based way to stop all... 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

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

Bluetooth Pairing Part 4: LE Secure Connetions - Numeric Comparison

Part 3, we had an overview about LE Legacy pairing with passkey. Other than LE Legacy pairing, LE Secure Connections is the other option for pairing. LE Secure Connections is an enhanced security feature introduced in Bluetooth v4.2. It uses a Federal Information Processing Standards (FIPS) compliant algorithm called Elliptic Curve Diffie Hellman (ECDH) for key generation. For LE Secure Connections, it support four association models: Just Works Numeric Comparison (Only for LE Secure Connections) Continue Reading

How to Deploy Bluetooth Secure Gateway on Intel Edison

Bluetooth SIG released an advanced toolkit, the Bluetooth Secure Gateway, last September. With this toolkit, you can learn how to connect your Bluetooth devices to the Internet of Things. The hands-on labs in this kit will help you familiarize yourself with how to set up the popular ARM-based Raspberry Pi2/Pi3 to act as a secure gateway for your Bluetooth low energy devices. I became curious to see if there any other popular dev boards which could run the Bluetooth Secure Gateway aside from one... Continue Reading

Bluetooth 5 is Here

Bluetooth 5

Rejoice developers, Bluetooth 5 has arrived! And with it, a lot of buzz is being generated about its capabilities. I’d like to dive into the meat of some of the more popular features a bit and then talk more about my personal favorite.  Increased Bandwidth One of the key features of Bluetooth 5 is the ability to get 2Msps (mega symbols per second, or megabits when talking in context of low energy for this blog) out of Bluetooth low energy. This is done in the same power envelope as low energy today... Continue Reading

This Wearable is Changing How Endurance Athletes Train

On this week’s episode of IoT Podcast with Stacey Higginbotham, Alessandro Babini, the CEO of Bluetooth SIG member company Humon, had the opportunity to talk about the benefits the Humon Beta wearable delivers to athletes. The Humon wearable helps endurance athletes train smarter by monitoring the way their muscles are using oxygen in real-time. The wearable straps onto the athlete’s thigh and pairs via Bluetooth technology with your smartphone to monitor your muscle oxygenation level, making recommendations... Continue Reading
