Classification: CPC H  G | IPC G  H

Claim 5:
6. A Bluetooth device set (102) of a Bluetooth communication system (100), comprising:
a first member device (120), comprising:
a first communication circuit (121), arranged to operably conduct wireless communications with a Bluetooth host device (110) in the Bluetooth communication system (100);
a first cypher key generation circuit (123); and
a first control circuit (125), coupled with the first communication circuit (121) and the first cypher key generation circuit (123), and arranged to operably generate a first resolvable set identifier (RSI-1) corresponding to the first member device (120) according to a device set identification information corresponding to the Bluetooth device set (102), to operably generate one or more target Bluetooth advertising packets containing an auto-pair request and a device information of the first member device (120), and to operably utilize the first communication circuit (121) to transmit the one or more target Bluetooth advertising packets to the Bluetooth host device (110);

a second member device (130), comprising:
a second communication circuit (131), arranged to operably conduct wireless communications with the Bluetooth host device (110); and
a second control circuit (135), coupled with the second communication circuit (131), and arranged to operably control operations of the second communication circuit (131), and arranged to operably generate a second resolvable set identifier (RSI-2) corresponding to the second member device (130) according to the device set identification information;

wherein the Bluetooth host device (110) identifies the first member device (120) as a first privileged device according to the auto-pair request in the one or more target Bluetooth advertising packets, and after identifying the first member device (120) as the first privileged device, the Bluetooth host device (110) transmits a first privileged pairing notice to the first member device (120), and generates a first cypher key (Key-1);
wherein the first control circuit (125) is further arranged to operably generate a second cypher key (Key-2) corresponding to the first cypher key (Key-1) after the first privileged pairing notice is received by the first communication circuit (121).
