Bluetooth: Bluetooth Low Energy

Bluetooth Low Energy design engineers Panasonic
Bluetooth low energy functionality

For wireless communication devices that have been optimized for low power consumption rather than maximum data transfer rates, Bluetooth® low energy functionality technology fits the bill perfectly. It consumes as little as one-hundredth the average power required by Classic Bluetooth® technology.

Bluetooth® Smart technology achieves its low power consumption primarily by keeping its radio turned off most of the time. It scans only three advertising channels, and its radio awakens only to send or receive short bursts of data, with small packet sizes from 8 to 27 octets. Bluetooth® Smart technology can transmit authenticated data in as little as 3 ms, versus the 1000 ms typical for Classic Bluetooth® technology. All this relates in a maximum practical data rate well under 100 kbps typically. In Bluetooth® Smart technology each use case is allocated to one Bluetooth® Smart profile. For transmitting temperature the temperature profile and service are used. Profile and services are using the GATT-based architecture.

Bluetooth SIG is working on further improvements as do silicon manufacturer. At second generation Bluetooth® Smart ICs, so called “nanopower” Bluetooth, transmission power consumption will fall by about 66 per cent with no loss of range or performance.

Brand your product “Bluetooth Smart”

Typically, Bluetooth® Smart branded products are sensor or data collector devices transmitting data to a ‘hub’ device like a smartphone or tablet.
