Piconet
At the very heart of the Bluetooth technology is
the idea of forming small wireless networks
known as piconets. When a Bluetooth device
has established a link to one or more other
devices, a piconet has been formed. The
device that initiates a connection acts as the
master. The other devices are slaves.

The master controls all traffic in the piconet.
Communication between slaves can only take
place via the master. In the below example of a
piconet, the laptop (master) transmits to the
handheld computer (slave 1) and the mobile
phone (slave 2):
