This procedure is referred to as “key allocation”. The connection then needs to be authorized via a (usually four-digit) PIN which is displayed on the slave device’s screen or is recorded in the device’s manual. Depending on the device, it may be activated through a special software, control panel or button that displays the Bluetooth symbol. In practice, members of a piconet need to be close to one another and have activated Bluetooth on their respective devices. Connecting two or more devices via Bluetooth is called “ pairing”. The connection is then established within 1.28 seconds on average. Devices that want to connect to a piconet “listen” in scan mode every 2.56 seconds for a signal from the master. The connection is maintained until the master disables Bluetooth in their system. the other devices involved) and set up a piconet (a Bluetooth network). A connection can originate from any device which then becomes the “ master” over the “ slaves” (i.e. ![]()
