Qt Bluetooth
Bluetooth is a short-range (less than 100 meters) wireless technology. It has a reasonably high data transfer rate of 2.1 Mbit/s, which makes it ideal for transferring data between devices.
Bluetooth connectivity is based on basic device management, such as scanning for devices, gathering information about them, and exchaning data between them.
