Question

How several devices can communicate concurrently?

Answer 1

A Bluetooth device playing the role of the “master” can communicate with seven devices playing the role of the “slave”. This network of “group of up to eight devices” (1 master + 7 slaves) is known a piconet. A piconet is an ad-hoc computer network of devices employing Bluetooth technology protocols to let one master device to interconnect with up to seven active slave devices (since a three-bit MAC address is employed). Up to 255 further slave devices may be inactive, or parked, which the master device can bring into active status at any time.
