BLE

びーえるいー · BLE (Bluetooth Low Energy)

English: Bluetooth Low Energy

BLE (Bluetooth Low Energy) is a short-range wireless communication standard introduced in Bluetooth 4.0, designed for minimal power consumption. A typical button-cell battery can power a BLE device for months to years, making it well suited for IoT sensors and small devices communicating with nearby gateways. BLE operates independently from classic Bluetooth and does not support Wi-Fi access point communication or infrared.
