In this situation, the second communication circuit 131 may perform the operation 1218 of
As shown in
In the operation 1220, the processing circuit 117 may establish a connection with the second member device 130 through the host-side communication circuit 111 according to a device information of the second member device 130 (e.g., a Bluetooth device address of the second member device 130) transmitted from the first member device 120 in the operation 602, and may decide a second parameter P2. The processing circuit 117 may adopt the same approach as employed in the aforementioned operation 314 to decide the second parameter P2. Accordingly, the foregoing descriptions regarding how to decide the second parameter P2 in the operation 314 are also applicable to the operation 1220, and will not be repeated here for the sake of brevity. The processing circuit 117 may also transmit the second parameter P2 or a second field indication to the first member device 120 through the host-side communication circuit 111 in the operation 1220, wherein the second field indication is utilized for indicating a specific packet field whose content is to be utilized as the second parameter P2.
