Abstract

A method applied to a wireless Bluetooth audio communication system includes: providing an audio gateway of a first piconet to communicate with a master device in the first piconet and to transmit at least one packet of audio stream to the master device and a slave device; employing a first transceiver as the master device to receive the at least one packet of the audio stream from the audio gateway; and, employing a second transceiver as the slave device to receive the at least one packet of the audio stream from the audio gateway and to acknowledge the first transceiver whether the second transceiver has successfully received the at least one packet of the audio stream from the audio gateway.

Claims10

Dependent claims

A wireless Bluetooth audio communication system, comprising:

an audio gateway of a piconet, configured to communicate with a master device in the piconet and to transmit at least one packet of audio stream to the master device and a slave device;
a first transceiver used as the master device, configured to receive the at least one packet of the audio stream;
and
a second transceiver used as the slave device, configured to receive the at least one packet of the audio stream transmitted from the audio gateway and configured to acknowledge to the first transceiver whether the second transceiver has successfully received the at least one packet of the audio stream;
wherein the first transceiver is further arranged to transmit a packet having a negotiation configuration command to the second transceiver, and the second transceiver is arranged to send a corresponding acknowledgement packet to the first transceiver if the packet having the negotiation configuration command has been successfully accepted by the second transceiver;
and a different packet of the audio stream is to be discarded by the first transceiver if the first transceiver is transmitting the packet having the negotiation configuration command to the second transceiver to negotiate with the second transceiver.

A transceiver of a wireless Bluetooth audio communication system in which an audio gateway of a piconet is arranged to communicate with a master device in the piconet and to transmit at least one packet of audio stream to the master device and a slave device, the transceiver being used as the master device and comprising:

a communication circuit, configured to receive the at least one packet of the audio stream from the audio gateway;
and
a processing circuit, coupled to the communication circuit, configured to control the communication circuit to acknowledge to the audio gateway whether the transceiver has successfully received the at least one packet of the audio stream and the slave device has successfully received the at least one packet of the audio stream from the audio gateway;
wherein the transceiver is further arranged to transmit a packet having a negotiation configuration command to the slave device;
and, a different packet of the audio stream from the audio gateway is to be discarded by the transceiver if the transceiver is transmitting the packet having the negotiation configuration command to the slave device to negotiate with the slave device.
