480

What is claimed is:

1 . A Bluetooth master device, comprising:

a transceiver; and

485 a processor configured to enable the Bluetooth master device to perform mixed mode communication with a Bluetooth slave device by the processor being configured to:

control the transceiver to transmit to the Bluetooth slave device a data packet based on a Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol; and 490 receive from the Bluetooth slave device via the transceiver an acknowledgement packet (ACK) based on a Bluetooth Low Energy (BLE) protocol.

2. The Bluetooth master device of claim 1 , wherein the processor is configured to: determine a time to enable the mixed mode communication; and

495 at the enable time, enable the mixed mode communication.

3. The Bluetooth master device of claim 2, wherein the processor is configured to: after the mixed mode communication is enabled, expect to receive the ACK from the Bluetooth slave device via the transceiver within a period of time which is 500 based on inter frame spacing of the BLE protocol.

4. The Bluetooth master device of any of claims 1 -3, wherein the processor is configured to:

determine whether the Bluetooth slave device supports the mixed mode 505 communication.

5. The Bluetooth master device of claim 1 , wherein the processor is configured to: receive from the Bluetooth slave device via the transceiver the ACK in accordance with an ACK aggregation scheme based on aggregating ACKs during an 510 aggregation window.

6. The Bluetooth master device of claim 6, wherein the aggregation window comprises a number of data packets that can be transmitted to the Bluetooth slave device without the Bluetooth slave device transmitting the ACK.

515

7. The Bluetooth master device of claim 6, wherein the aggregation window is maintained on the transceiver and is incremented by one each time an ACK is received up to a maximum of four.

520 8. The Bluetooth master device of claim 6, wherein the processor is configured to:

measure a quality of a communication channel between the Bluetooth master device and the Bluetooth slave device; and

if the communication channel quality exceeds a predetermined channel quality threshold, enable an ACK aggregation scheme based on aggregating ACKs over an 525 aggregation window.

9. The Bluetooth master device of claim 8, wherein the processor is configured to provide the aggregation window to the Bluetooth slave device via the transceiver.

530 10. The Bluetooth master device of claim 8, wherein the processor is configured to:

enable the ACK aggregation scheme at a selected time.

1 1. The Bluetooth master device of claim 8, wherein the processor is configured to: determine when the communication channel quality falls below the

535 predetermined channel quality threshold; and

disable the ACK aggregation scheme when the communication channel quality falls below the predetermined channel quality threshold.

12. The Bluetooth master device of claim 8, wherein the processor is configured to: 540 determine the quality of the communication channel after the communication channel has been measured for a predetermined period of time.

13. The Bluetooth master device of any of claims 1 -3, wherein a modulation rate of the Bluetooth BR/EDR protocol is higher than a modulation rate of the BLE protocol. 545

14. The Bluetooth master device of any of claims 1 -3, wherein the processor is configured to:

initiate the mixed mode communication.

550 15. The Bluetooth master device of any of claims 1 -3, wherein the mixed mode communication is initiated by the Bluetooth slave device.

16. A Bluetooth slave device, comprising:

a transceiver; and

555 a processor configured to enable the Bluetooth slave device to perform mixed mode communication with a Bluetooth master device by the processor being configured to:

receive from the Bluetooth master device via the transceiver a data packet based on a Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol; and

560 control the transceiver to transmit to the Bluetooth master device an acknowledgement packet (ACK) based on a Bluetooth Low Energy (BLE) protocol.

17. The Bluetooth slave device of claim 16, wherein the processor is configured to: determine a time to request the mixed mode communication; and

565 at the request time, request the mixed mode communication.

18. The Bluetooth slave device of any of claims 17-17, wherein the processor is configured to:

control the transceiver to transmit to the Bluetooth master device the ACK in 570 accordance with an ACK aggregation scheme based on aggregating ACKs during an aggregation window.

19. The Bluetooth slave device of claim 18, wherein the aggregation window comprises a number of data packets that can be received by the Bluetooth slave

575 device without the Bluetooth slave device transmitting the ACK.

20. The Bluetooth slave device of claim 18, wherein the aggregation window is maintained on the transceiver and is incremented when a next expected sequence number of a received data packet is different from a next expected sequence number

580 of a previously received data packet.

21. The Bluetooth slave device of any of claims 16-17, wherein the processor is configured to:

initiate the mixed mode communication by sending a request to the master 585 device requesting that the master device enable the mixed mode communication.

22. The Bluetooth slave device of any of claims 16-17, wherein the processor is configured to control the transceiver to transmit the ACK without using an external power amplifier.

590

23. A communication method, comprising:

establishing a Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) communication link between a master device and a slave device;

enabling, by either the master device or the slave device, a mixed mode 595 communication based on a combination of the Bluetooth BR/EDR protocol and a Bluetooth Low Energy (BLE) protocol;

transmitting by the master device to the slave device a data packet based on the Bluetooth BR/EDR protocol; and

transmitting by the slave device to the master device an acknowledgement 600 packet (ACK) based on the BLE protocol.

24. The communication method of claim 23, further comprising:

measuring a quality of a communication channel between the Bluetooth master device and the Bluetooth slave device; and

605 if the communication channel quality exceeds a predetermined channel quality threshold, enabling an ACK aggregation scheme based on aggregating ACKs over an aggregation window.

25. The communication method of claim 24, further comprising:
