As shown in FIG. 5, the Bluetooth host device 110 may perform the operation 218 of FIG. 5 and subsequent operations after generating the first cypher key Key-1, and the first member device 120 may perform the operation 220 of FIG. 5 and subsequent operations after generating the second cypher key Key-2.
Similarly, the second control circuit 135 of the second member device 130 may perform the operation 306 of FIG. 5 at an appropriate time to generate a resolvable set identifier RSI-2 corresponding to the second member device 130. For example, the second control circuit 135 may perform the aforementioned target algorithm according to the device set identification information Set-ID of the Bluetooth device set 102 to generate a random address, and utilize the random address to be the resolvable set identifier RSI-2 corresponding to the second member device 130. In practice, the second control circuit 135 may perform the operation 306 of FIG. 5 at any time point between the operation 402 of FIG. 4 through the operation 220 of FIG. 5, or at a certain time point before the operation 402 of FIG. 4.
