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.

Abstract: A radio-frequency transceiver device includes a transmission circuit generating a transmission signal at a transmission pad connected to a transmission antenna by modulating a radio frequency signal as a function of a control signal. First and second reception circuits receive first and second signals at first and second reception pads connected to first and second reception antennas.

A reception error signal indicating a reception error is generated when the test indicates that the received first and second reception signals do not correspond.
