摘要： 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.

摘要： 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.

摘要： A method applied into a controller of a Bluetooth device includes: providing a first flag and a second flag which are configured as a default value respectively; changing the first flag from the default value when the controller successfully receives the particular packet transmitted from the audio gateway; changing the second flag from the default value 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 detecting that either the first flag or the second flag changes and becomes different from the default value.

摘要： There is provided a fast paging procedure in which a master device repeatedly sends the paging message to a slave device using predetermined channel frequencies, wherein a selection of the predetermined channel frequencies is not calculated or predicted from the slave's Bluetooth device address. When the master device receives a slave page response message at one frequency among the predetermined channel frequencies, the master device transmits an FHS packet to the slave device at the same frequency in which the slave page response message was received.

摘要： There is provided a Bluetooth audio system including a gateway, a primary device and at least one slave device. The gateway and the primary device communicate Bluetooth packets therebetween based on the standard Bluetooth communication protocol. The at least one slave device accomplishes synchronization with the primary device using a user-defined Bluetooth communication protocol so as to listen or snoop the Bluetooth packets exchanged between the gateway and the primary device.
