A method applied into a controller of a wireless Bluetooth device includes: providing a first flag and a second flag; asserting the first flag when the controller successfully receives the particular packet transmitted from the audio gateway; asserting the second flag when the controller successfully receives an acknowledgement from a secondary device wherein a reception of the acknowledgement indicates that the secondary device successfully receives the particular packet; and transmitting an acknowledgement of a particular packet to an audio gateway when the first flag and the second flag are asserted.

Wireless Bluetooth communication mechanism capable of effectively reducing number of audio packet retransmission

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.

Bluetooth audio communication system and method for acknowledging reception of packets of audio streams at a slave and master devices

A method applied into a wireless Bluetooth device includes: receiving a particular packet from an audio gateway through a first piconet; receiving a first acknowledgement from a secondary device through a second piconet, the first acknowledgement corresponding to a retransmission of the particular packet; and transmitting a second acknowledgement corresponding to the particular packet to the audio gateway through the first piconet when the particular packet is received through the first piconet and the first acknowledgement corresponding to the retransmission of the particular packet is received through the second piconet.
