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 and the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device. But the auxiliary Bluetooth circuit switches from the sniffing mode to a relay 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 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 transmitted from the remote Bluetooth device.
