Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 4:
5. The Bluetooth communication system (100) of claim 4, wherein the processing circuit (117) is further arranged to operably utilize the host-side communication circuit (111) to transmit a second parameter (P2) or a second field indication to the second member device (130) after identifying the second member device (130) as the second privileged device, and to operably execute the predetermined cypher key algorithm according to the second parameter (P2) to generate a third cypher key (Key-3);
wherein the second control circuit (135) is further arranged to operably execute the predetermined cypher key algorithm according to the second parameter (P2) to generate a fourth cypher key (Key-4) corresponding to the third cypher key (Key-3) after the second parameter (P2) or the second field indication is received by the second communication circuit (131).
