Abstract

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.

Claims

1. A method applied into a wireless Bluetooth device, comprising:

receiving a particular packet from an audio gateway through a first piconet;

transmitting a particular acknowledgement to the audio gateway through the first piconet when the particular packet is received and an acknowledgement corresponding to the particular packet is received through a second piconet.

2. The method of claim 1, wherein the particular packet from the audio gateway through the first piconet is received at a first time slot, and the acknowledgement corresponding to the particular packet received through the second piconet is at a second time slot which is different from the first time slot.

3. The method of claim 1, wherein the second time slot is later than the first time slot, and the particular acknowledgement is transmitted to the audio gateway through the first piconet at a specific time slot next to the second time slot.

4. The method of claim 1, wherein the first time slot is later than the second time slot, and the particular acknowledgement is transmitted to the audio gateway through the first piconet at a specific time slot next to the first time slot.
