Abstract

A Bluetooth communication system includes: a Bluetooth host device; and a Bluetooth device set which including a first member device and a second member device. The Bluetooth host device controls a display device to display a candidate device list, and to display a single device item in the candidate device list to represent the Bluetooth device set, but does not simultaneously display two device items in the candidate device list to represent the first member device and the second member device. The Bluetooth host device generates a first cypher key according to an instruction from the first member device and a device information of the first member device after receiving a selection command. The first member device establishes a connection with the Bluetooth host device, and generates a second cypher key corresponding to the first cypher key according to a device information of the Bluetooth host device.
