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
