A little bit of history
Bluetooth® is a communication standard developed in the mid-90s that allows wireless connections between electronic devices. It enables the bidirectional exchange of data at short distance. The Bluetooth SIG (Special Interest Group) is the organization that oversees the development of the various Bluetooth standards and manages licenses for manufacturers. It includes major companies such as IBM, Nokia, Intel and Apple.
Classic Bluetooth® VS Bluetooth® Smart
Classic Bluetooth is mainly used in mobile phones, laptops or wireless headsets. It enables the exchange of data over distances up to 100 meters.By exchanging with members of the Consortium, the Bluetooth SIG has identified new needs requiring substantial changes in the specification of the Bluetooth technology. In 2011, the Bluetooth Smart was announced as a parent technology of Classic Bluetooth. It enables new applications in the Internet of Things in particular. Bluetooth Smart is used to exchange data over shorter distances than Classic Bluetooth (30m) but it consumes much less energy.
Bluetooth® Smart Ready
To ensure compatibility between Bluetooth devices and Bluetooth Smart devices, connected objects can combine the two technologies: it’s called Bluetooth Smart Ready. For example, most smartphones use both Bluetooth technologies following the needs of the users.
