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.
