Chapter 2 of the Bluetooth Mesh Networking Series Introduction In Part 1 of this article, I introduced the new Bluetooth mesh networking technology. If you haven’t read part 1, start there before reading this, the second part. I’ll complete my introductory overview of Bluetooth mesh networking here with an overview of the way messages find their way across large mesh networks, in-market device support, security and the mesh stack itself, and then we’ll proceed to explore aspects of the technology...

Chapter 1 of the Bluetooth Mesh Networking Series Introduction Bluetooth technology is one of the world's best known brands and one of the most ubiquitous wireless communications technologies on the planet. It's been in existence since 2000 and has found its way into billions and billions of devices. Last year alone, over three billion Bluetooth devices were shipped by manufacturers. Bluetooth has not stood still. Since its first incarnation, Bluetooth has been carefully and systematically improved... 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

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

Hybrid Mobile Applications Part 2

Introduction In Part 1, I explored some of the practical challenges which mobile application developers face, when they want their application to be available on multiple platforms. I contrasted the building of platform-specific, native applications with cross-platform web applications which execute within a web browser. I went on to introduce the “hybrid mobile application”, which would appear to offer the best of both worlds, allowing the developer to create one set of application source code... Continue Reading

Hybrid Mobile Applications and Bluetooth Technology – Part 1

Introduction A mobile developer’s job is not an easy one. Ensuring their killer application is available to as many people on the planet as possible may mean developing four, five or possibly more versions of the application to enable it to run on the full variety of mobile platforms. Android and iOS dominate the market, but don’t forget about Windows Phone, BlackBerry 10 and Tizen. In some sectors and geographies, platforms with a smaller global market share have a disproportionately larger significance. Continue Reading

Bluetooth Developer Starter Kit version 3

Bluetooth Developer Starter Kit

Introduction If you’re new to developing Bluetooth applications or firmware, the Bluetooth Developer Starter Kit (BDSK) is the perfect resource for you. It consists of several coding projects for you to complete, starting with an Arduino 101 project, which leads you one step at a time through the process of designing and implementing a custom Bluetooth profile on the Arduino. This allows a smartphone application to control a custom circuit connected to the Arduino. Once you’ve completed the Arduino... Continue Reading

The BBC Robot Wars micro:bit Coding Challenge

microbit-controller

Robot Wars is a BBC TV show featuring robots...and war.Robot Wars works like this. Contestants, usually teams of two or more, build awe-inspiring, battling robots. They bring them on the show and fight other contestants’ robots in a purpose-built arena—all the time keeping an eye open for the fearsome and deadly house robots. You win a bout by immobilsing (e.g. by completely destroying) all the other robots or, if no clear winner emerges when time runs out, by judges’ decision. The judges assess... Continue Reading
