What is Bluetooth Low Energy? You need to know

Since the first version of the Bluetooth transmission standard was released, many other forms appeared with additional improvements. Bluetooth Low Energy, in particular, received increasing popularity, as the low-power development allowed the standard to be incorporated into smaller devices.

What is Bluetooth Low Energy

Bluetooth Low Energy is the Bluetooth versions 4.0, 4.1 and 4.2, which are ideally suited to be installed in fitness trackers, smartwatches or even smartphones due to their low energy consumption. This is precisely why the standard is so widespread and is supported by almost every new device.

1. Bluetooth Low Energy builds on the radio technology Wibree, which was developed by Nokia.
2. After the Bluetooth Special Interest Group merged the two technologies, the classic Bluetooth with Wibree became Bluetooth version 4.
3. Bluetooth Low Energy is fully backward compatible within the Low Energy series. However, can usually not be combined with devices that have version 2.0 or 3.0.
4. Because Bluetooth Low Energy has a lower transmission power, the range is also lower with 10 to 40 meters.
5. In addition, Bluetooth LE is usually slower than classic Bluetooth.

More information about Bluetooth Low Energy

In Bluetooth LE, devices can take different roles. While some devices only receive data (Observer),data from devices in the Broadcaster role are only transmitted. In addition, Bluetooth Low Energy distinguishes between Peripheral devices, which send connection requests as slaves, and Central devices, which act as masters and do not send connection requests.
