Claim 4:
5. 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-I) corresponding to the first member device (120) according to a device set identification information corresponding to the Bluetooth device set (102), and arranged to operably utilize the first communication circuit (121) to transmit a device information of the first member device (120) 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) controls a display device (150) to display a candidate device list, and to display a single device item for representing the Bluetooth device set (102) in the candidate device list, but does not simultaneously display two device items for respectively representing the first member device (120) and the second member device (130) in the candidate device list;
wherein the Bluetooth host device (110) establishes a connection with the first member device (120) after receiving a selection command issued by a user, and generates a first cypher key (Key-1) according to instructions of the first member device (120) and the device information of the first member device (120);
wherein the first control circuit (125) is further arranged to operably utilize the first communication circuit (121) to establish a connection with the Bluetooth host device (110), and to operably generate a second cypher key (Key-2) corresponding to the first cypher key (Key-1) according to a device information of the Bluetooth host device (110); and
wherein the first control circuit (125) is further arranged to operably generate an indication value when establishing a connection with the Bluetooth host device (110), and arranged to operably utilize the first communication circuit (121) to transmit the indication value to the Bluetooth host device (110), and to operably utilize the first communication circuit (121) to transmit the indication value and the device information of the Bluetooth host device (110) to the second member device (130).
