• A Piconet is the basic Bluetooth network unit.

  • It consists of one master device and up to seven active slave devices connected in an ad-hoc manner.

  • The master controls communication and timing, while slaves synchronize to the master’s clock.

  • Devices communicate using time-division duplexing (TDD), taking turns to send and receive data.

  • Example: A smartphone (master) connected to a wireless headset, a smartwatch, and a fitness tracker (slaves) forms a piconet.
