The same antenna as for Wi-Fi is used for Bluetooth communication.

Working with services

Different devices support their own set of Bluetooth services such as file transfer, operating as network cards, audio playback device, etc. The opportunity to work with these services is described in the documentation for software [BlueZ|http://www.bluez.org/ BlueZ], in the documentation for the devices and on specialized forums. The use of each service requires a corresponding configuration.
