Smartwatches & Trackers Bluetooth v 3

Bluetooth v.3

— initially, Bluetooth, regardless of version, is a standard that provides a direct wireless connection between various devices at a distance of up to 10 m. The presence of a Bluetooth module is almost mandatory for any modern smartphone; different versions are quite compatible with each other. However, to use all the features, you usually need to support the corresponding version on both devices. Bluetooth v.3 is one of the most common options today; it includes a standard Bluetooth module, similar to the previous v.2, a high-speed add-on for working with large files, as well as some power consumption improvements.
