Bluetooth® Dual Mode technology builds the centre of the Bluetooth ecosystem in combining Classic Bluetooth® technology and Bluetooth® Smart Ready technology in one device. These so called dual-mode modules combine both communication stacks and permit a shared antenna. It can communicate with other devices implementing both technologies as well as devices implementing either technology and therefore can easily be added to ‘hub’ devices, e.g. for industrial, automation, medical and fitness products. Single-mode and dual-mode devices are respectively designated as Bluetooth® Smart and Bluetooth® Smart Ready.
Some profiles and use cases will be supported by only one of the technologies. Therefore, devices implementing both technologies have the ability to support the most use cases.
