What is Bluetooth LE and how does it differ from traditional Bluetooth?
Bluetooth LE, also known as Bluetooth Low Energy, is a variant of the traditional Bluetooth technology. It is designed to provide a low-power, low-bandwidth alternative for devices that require intermittent or periodic data transfer. Bluetooth LE is optimized for applications that require low power consumption, such as fitness trackers, smart home devices, and IoT sensors.
Unlike traditional Bluetooth, which is designed for continuous data transfer and requires more power, Bluetooth LE is designed for intermittent data transfer and requires significantly less power. This makes it ideal for devices that are battery-powered and need to run for extended periods of time. Bluetooth LE also has a shorter range than traditional Bluetooth, typically around 100 meters, but this can vary depending on the device and environment.
