In the operation 1010, 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 transmit a device information of the Bluetooth host device 110 (e.g., a Bluetooth device address of the Bluetooth host device 110) to the first member device 120.
In this situation, the first communication circuit 121 may perform the operation 1012 to receive the device information of the Bluetooth host device 110, and may establish a connection with the Bluetooth host device 110 under control of the first control circuit 125. In addition, the first control circuit 125 further generate an indication value required for conducting the Bluetooth pairing between the Bluetooth host device 110 and the first member device 120 in the operation 1012.
In one embodiment, the aforementioned indication value is a predetermined value, a random value, a predetermined address, a random address, a predetermined string, a random string, a predetermined token, a random token, or the like for use in a predetermined cypher key algorithm. In another embodiment, the aforementioned indication value is an algorithm identifier corresponding to a predetermined cypher key algorithm.
After generating the indication value, the first member device 120 may perform the operation 1014, the operation 1016, and the operation 1018.
