What is Bluetooth Low Energy?
Bluetooth is one of the most popular short-range communications technologies for wearable devices connected to mobile phones. Bluetooth Low Energy (BLE) is a new protocol with reduced power consumption well-suited for the Internet of Things software development. What differs BLE from the usual Bluetooth is the way it sends data: periodic transmissions of lesser amounts of data result in lower power consumption, which is surely appreciated by end users.
The Bluetooth Low Energy protocol is supported by all modern mobile phones starting from iOS 5, Android 4.3, Windows Phone 8, and BlackBerry 10.
How does Bluetooth Low Energy work?
There are 3 main types of BLE connection, each serving its particular purposes, and each being used in different products for different business domains:
- 1-to-1 connection is used for various fitness tracking wearables, smart home devices, and medical equipment.
2. 1-to-Many connection is often associated with item-tracking, way-finding, and point-of-interest beacons. A smartphone becomes the center of user activities.
3. Many-to-Many connection is most often related to sensor networks, home automation, and industrial use, connecting devices inside whole buildings.
The Internet of Things projects with Bluetooth Low Energy
Bluetooth Low Energy can be used in many Internet of Things spheres: from Smart Home and Automotive solutions to Fitness & Healthcare products.
The latest trends in Internet of Things predict rapid growth of IoT devices in all spheres of our everyday life along with the emergence of IoT marketplaces.
