An Introduction to BLE
As a low power-consuming Internet of Things (IoT) technology, BLE is highly capable of short-range wireless communication. Bluetooth Low Energy was developed as Wibree by Nokia in 2006, specifically as a low power-consuming wireless standard, in contrast to Bluetooth and Wi-Fi, which provide high data transfer and consume lots of power. Later in 2009, when Bluetooth 4.0 specification was launched, it became BLE.
BLE beacons, smart BLE devices, are popular for PAwR (Periodic Advertisement with Response) and bidirectional communication with BLE-enabled devices (Bluetooth 5.4) such as smartphones.
In this digital age, BLE finds many applications in smarthomes, indoor navigations, wearables, inventory management, periodic advertisement, retail operations, supply chain and logistics, etc.
