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

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

Turning Renewed Excitement into an Ecosystem for Everyone

Apple’s latest iPhone, the 7, shipped on Friday and is finding its way into consumer hands. This is the first wildly popular smartphone to shun the 3.5 mm headphone jack for audio. This doesn’t immediately mean all audio connectivity will be wireless – there is a dongle, there are options for lightning connected headphones and earbuds – but there is definitely renewed excitement around wireless audio and we are pretty excited as well. Streaming audio is frequently the first Bluetooth technology... Continue Reading
