A device may function either in a central or peripheral role. What is essential to understand when talking about BLE-equipped devices is the architecture behind the technology, particularly its asymmetry.
In other words: when not in use, it goes into sleep mode to conserve energy. For example, IoT devices tend to be constrained and require extended battery use, so BLE favors low power consumption over continuous data transfer. BLE was created with IoT applications in mind, which has particular implications for its design. Its goal is to connect devices over a relatively short range. What is Bluetooth Low Energy?īluetooth Low Energy is a wireless, low-power personal area network that operates in the 2.4 GHz ISM band. There are many commercial and business applications for this standard that made it so popular. But don't be fooled it's not just your smart band that has BLE. This is in no small part thanks to the explosion of the Internet of Things, which gave rise to a slurry of smart personal devices that needed common and efficient means of communication. Bluetooth Low Energy (BLE) is one of the most widely applicable low-power connectivity standards.
