From another aspect, the operation of filtering device items to be shown in the candidate device list conducted by the processing circuit 117 in the aforementioned operation 606 can simplify the complexity of user's manipulation during the Bluetooth pairing procedure, and can reduce the possibility of user's erroneous manipulation.
The user may manipulate the input circuit 113 to select the Bluetooth device set 102 as the object to be paired with the Bluetooth host device 110.
In this situation, the input circuit 113 may perform the operation 608 to receive a selection command issued by the user, and transmit the selection command to the processing circuit 117.
In the operation 610, the processing circuit 117 may establish a connection with the first member device 120 through the host-side communication circuit 111 according to the selection command, and conduct a pairing procedure to generate a first cypher key Key-1.
In this situation, the first control circuit 125 may perform the operation 612 to establish a connection with the Bluetooth host device 110 through the first communication circuit 121, and conduct the pairing procedure to generate a second cypher key Key-2 corresponding to the first cypher key Key-1.
