    Abstract: An auxiliary Bluetooth circuit for use in a multi-member Bluetooth device is disclosed including: a second Bluetooth communication circuit, a second packet parsing circuit, and a second control circuit. In a period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device, while the second control circuit utilizes the second Bluetooth communication circuit to sniff packets issued from the remote Bluetooth device. In a situation of that a throughput of packets sniffed by the auxiliary Bluetooth circuit is lower than a predetermined threshold, the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode. In a period during which the auxiliary Bluetooth circuit operates at the relay mode, the second control circuit utilizes the second Bluetooth communication circuit to receive packets forwarded from the main Bluetooth circuit.

    Abstract: A main Bluetooth circuit for use in a multi-member Bluetooth device is disclosed including: a first Bluetooth communication circuit, a first packet parsing circuit, and a first control circuit. In a period during which the auxiliary Bluetooth circuit operates at the sniffing mode, the first control circuit utilizes the first Bluetooth communication circuit to receive packets transmitted from the remote Bluetooth device. In a situation of that a throughput of packets sniffed from the remote Bluetooth device by the auxiliary Bluetooth circuit is lower than a predetermined threshold, the auxiliary Bluetooth circuit switches from the sniffing mode to the relay mode. In a period during which the auxiliary Bluetooth circuit operates at the relay mode, the first control circuit utilizes the first Bluetooth communication circuit to receive the packets transmitted from the remote Bluetooth device and to forward received packets to the auxiliary Bluetooth circuit.

    Abstract: A multi-member Bluetooth device includes: a main Bluetooth circuit capable of bidirectionally communicating with a remote Bluetooth device through a first Bluetooth communication circuit; and an auxiliary Bluetooth circuit capable of communicating with the main Bluetooth circuit through a data transmission circuit. While the main Bluetooth circuit utilizes the first Bluetooth communication circuit to communicate with the remote Bluetooth device, the auxiliary Bluetooth circuit utilizes a second Bluetooth communication circuit to sniff packets transmitted from the remote Bluetooth device. When detected that the auxiliary Bluetooth circuit has missed packets transmitted from the remote Bluetooth device, the main Bluetooth circuit transmits missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.

    Abstract: A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the auxiliary Bluetooth circuit sniffs packets transmitted from the remote Bluetooth device while the main Bluetooth circuit receives packets issued from the remote Bluetooth device, and the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the throughput of packets sniffed by the auxiliary Bluetooth circuit is lower than a predetermined threshold. In the period during which the auxiliary Bluetooth circuit operates at the relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit, and the auxiliary Bluetooth circuit does not sniff packets issued from the remote Bluetooth device.

    Abstract: A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device, and the auxiliary Bluetooth circuit does not sniff packets transmitted from the remote Bluetooth device. But the auxiliary Bluetooth circuit switches from the relay mode to a sniffing mode if the data type of packets transmitted from the remote Bluetooth device changes. In the period during which the auxiliary Bluetooth circuit operates at the sniffing mode, the auxiliary Bluetooth circuit sniffs packets issued from the remote Bluetooth device while the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device.

    Abstract: A main Bluetooth circuit of a multi-member Bluetooth device includes: a Bluetooth communication circuit; a data transmission circuit; and a control circuit arranged to operably conduct bidirectional packet transmission with a remote Bluetooth device through the Bluetooth communication circuit by utilizing a Bluetooth wireless transmission approach, and arranged to operably communicate data with other devices through the data transmission circuit. During the period in which the Bluetooth communication circuit conducts packet transmission with the remote Bluetooth device, an auxiliary Bluetooth circuit of the multi-member Bluetooth device sniffs packets transmitted from the remote Bluetooth device. When the control circuit has detected that the auxiliary Bluetooth circuit missed packets transmitted from the remote Bluetooth device, the control circuit is further arranged to operably transmit missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.
