Integrating the Web, Apps, and Beacons

Developer Kits from Bluetooth SIG

Bluetooth Beacons, they’re all the rage.  Retail stores use them to broadcast offers to customers.   Subway stations and other locations with limited connectivity use Bluetooth Beacons to broadcast location information to travelers and commuters.  Whether aiding us in a subway station, guiding people to their favorite exhibits in a museum, or ushering passengers through unfamiliar airports to local services and connecting flights, Bluetooth Beacons are a basic element as we build Smart Cities and...

What Bluetooth Developers Should Know About Android O

Android Robot

Google officially announced Android O on May 17 at its developer conference, Google I/O. Android O is now available to ordinary users. As in the past, Google had initially released a developer preview version, to give them an overview of the next generation of Android[1]. Let’s take a look at what Android O means for Bluetooth developers. First of all, I’d like to tell you how Android versions are named. Google uses letters of the alphabet, allocated at each new release in alphabetical order. Those... Continue Reading

Bloodhound Race for the Line and Bluetooth

1000mph in a car No, that’s not a typo. One thousand miles per hour (mph). In a car. Gulp! Bloodhound SSC is a British, supersonic land vehicle being built for the purpose of achieving a new land speed world record. The current world record is held by Wing Commander Andy Green, a British Royal Air Force pilot, who achieved a speed of 760 mph in 1997. The goal of the Bloodhound SSC project is to achieve or exceed 1000 mph. As you’d imagine, a project like this, will encounter and need to solve, all... Continue Reading

Extending the Reach of the Web to Bluetooth Devices

There's this new thing called the World Wide Web Do you remember life before the internet? Or more to the point, before the World Wide Web (WWW)? No? OK. But you do remember life before Facebook, right? No? Oh dear. You're clearly just trying to make me feel old. And succeeding. Well thank you very much! Because some of us, myself included, do indeed remember life before the WWW. Just about. A long time ago in a galaxy actually not very far away at all.... The WWW was born. And for a good while, 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

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

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
