摘要

A Bluetooth communication system includes: a Bluetooth host device; and a Bluetooth device set which including a first member device and a second member device. The first member device transmits a device information of the first member device to the Bluetooth host device. The Bluetooth host device controls a display device to display a candidate device list, and to display a single device item in the candidate device list to represent the Bluetooth device set, but does not simultaneously display two device items in the candidate device list to represent the first member device and the second member device. The Bluetooth host device further establishes a connection with the first member device to conduct pairing procedure to generate a first cypher key after receiving a selection command. The first member device further establishes a connection with the Bluetooth host device to conduct pairing procedure to generate a second cypher key.

說明書

For another example, in FIG. 3 and FIG. 5, the operation 310 and the operation 304 may be performed in a reverse order, or may be performed at the same time.

For another example, in FIG. 3 and FIG. 5, the operation 318 may be performed at the same time with the operation 314, or may be performed before transmitting the second privileged pairing notice, the second parameter P2, and/or a second field indication related to the second parameter P2.

For another example, in FIG. 4, the operation 408 may be performed at the same time with the operation 410 or the operation 412, or may be performed between the operation 410 and the operation 412, or may be performed between the operation 412 and the operation 210.

For another example, in FIG. 7, the operation 708 and the operation 616 may be performed in a reverse order, or may be performed at the same time.

For another example, in FIG. 8, the operation 806 and the operation 804 may be performed in a reverse order, or may be performed at the same time.

For another example, in FIG. 9, the operation 806 and the operation 904 may be performed in a reverse order, or may be performed at the same time.
