This decision was made to "simplify marketing, and communicate user benefits more effectively". One change on the marketing side is that the point number was dropped, so it is now just called Bluetooth 5 (and not Bluetooth 5.0 or 5.0 LE like for Bluetooth 4.0). The Bluetooth SIG officially unveiled Bluetooth 5 on 16 June 2016 during a media event in London. ![]() ![]() A number of other manufacturers released Bluetooth Low Energy Ready devices in 2012. The first smartphone to implement the 4.0 specification was the iPhone 4S, released in October 2011. The technology was marketed as Bluetooth Smart and integration into version 4.0 of the Core Specification was completed in early 2010. After negotiations with Bluetooth SIG members, an agreement was reached in June 2007 to include Wibree in a future Bluetooth specification as a Bluetooth ultra low power technology. Īfter further development with partners, in particular Logitech and within the European project MIMOSA, and actively promoted and supported by STMicroelectronics since its early stage, the technology was released to the public in October 2006 with the brand name Wibree. The results were published in 2004 using the name Bluetooth Low End Extension. The company began developing a wireless technology adapted from the Bluetooth standard which would provide lower power usage and cost while minimizing its differences from Bluetooth technology. In 2001, researchers at Nokia determined various scenarios that contemporary wireless technologies did not address. compatibility with a large installed base of mobile phones, tablets, and computers.low power requirements, operating for "months or years" on a button cell.The Bluetooth SIG identifies a number of markets for low-energy technology, particularly in the smart home, health, sport, and fitness sectors. With the May 2016 Bluetooth SIG branding information, the Bluetooth SIG began phasing out the Bluetooth Smart and Bluetooth Smart Ready logos and word marks and reverted to using the Bluetooth logo and word mark in a new blue color. Bluetooth Smart indicates a low energy-only device which requires either a Smart Ready or another Smart device in order to function.Bluetooth Smart Ready indicates a dual-mode device compatible with both classic and low energy peripherals.In 2011, the Bluetooth SIG announced the Bluetooth Smart logo so as to clarify compatibility between the new low energy devices and other Bluetooth devices. īranding The previously used Bluetooth Smart logo ![]() Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as macOS, Linux, Windows 8, Windows 10 and Windows 11, natively support Bluetooth Low Energy.īluetooth Low Energy is distinct from the previous (often called "classic") Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol, but the two protocols can both be supported by one device: the Bluetooth 4.0 specification permits devices to implement either or both of the LE and BR/EDR systems.īluetooth Low Energy uses the same 2.4 GHz radio frequencies as classic Bluetooth, which allows dual-mode devices to share a single radio antenna, but uses a simpler modulation system. ![]() The original specification was developed by Nokia in 2006 under the name Wibree, which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy.Ĭompared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. It is independent of classic Bluetooth and has no compatibility, but Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and LE can coexist. Low-power wireless personal area network technology designed and marketed by the Bluetooth SIGīluetooth Low Energy ( Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart ) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
