Abstract
A main Bluetooth circuit and an auxiliary Bluetooth circuit of a multi-member Bluetooth device for communicating data with a remote Bluetooth device are disclosed. 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.
