Interoperability for Smart Lighting Platforms

Interoperability is something we take for granted when it comes to Bluetooth devices – just connect it and forget it. No need to look at a compatibility chart to figure out which Bluetooth enabled speaker will work with which Bluetooth enabled smartphone. Unfortunately, lighting control systems have never been this easy, until now. The Walled Garden In the lighting controls world, the topic of interoperability causes plenty of headaches. Many vendors take a walled garden approach, offering propriety... Continue Reading

Ericsson Presents Large-Scale Building Automation Test Case for Mesh Networking

As featured on IoT Agenda. Mesh networking is key to the success of the Internet of Things (IoT). In comparison to traditional wired counterparts, mesh networks are less expensive to implement, more adaptable and scalable, and offer greater reliability for high-traffic implementations. While niche technologies such as Thread and ZigBee have standardized mesh support, a limited install base and unpredictable performance, reliability, scalability, and interoperability have created challenges for an...

Beacons and Bluetooth: Bridging the Physical and Digital Worlds

Kontakt.io’s Hannah Augur explores how Bluetooth 5 technology and beacons are creating a powerful foundation for the IoT, bridging the physical and digital worlds. More data was created in the last two years than in the past 5,000 years combined. Everyday people and businesses are already experiencing the exponential growth of technology and data, and we have only begun crossing the chasm. While Industry 4.0 signaled the irreversible introduction of AI into industry, the real question is: what lies... Continue Reading

A New Way to Navigate

Bluetooth beacons provide wayfinding services to travelers in airports

Your smartphone makes it easy to locate any restaurant in the heart of downtown, but it’s not much help getting you through a crowded airport. That is unless you’re travelling through London’s Gatwick Airport. Spot the Dot Recently, Gatwick Airport installed around 2,000 beacons in two terminals, creating an indoor navigation system more reliable than traditional GPS. This beacon-based positioning system, built on Bluetooth technology, is the world’s first for an airport. The system uses Pointr... 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

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
