Abstract

An example apparatus includes: a memory; instructions in the apparatus; and a Bluetooth controller to execute the instructions to: enable circuitry to receive a synchronized transmission; determine if a synchronized transmission is received during a first duration; increment the first duration to a second duration as a result of not receiving the synchronized transmission during the first duration; and determine a third duration based on a determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

First claim

What is claimed is:

1. An apparatus comprising:
memory;
instructions in the apparatus; and
a Bluetooth controller to execute the instructions to:
enable circuitry to receive a synchronized transmission;
determine if a synchronized transmission is received during a first duration;
increment the first duration to a second duration as a result of not receiving the synchronized transmission during the first duration; and
determine a third duration based on a determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

2. The apparatus of claim 1 , wherein the first duration represents a first reception window, further including a second reception window, the second reception window has a duration equal to the second duration as a result of not receiving the synchronized transmission after enabling the circuitry to receive the synchronized transmission for the first duration.

3. The apparatus of claim 1 , wherein the Bluetooth controller further includes instructions to enable the circuitry to receive the synchronized transmission after a fourth duration, the fourth duration is determined based on the determined difference in time between enabling the circuitry to receive the synchronized transmission and receiving the synchronized transmission.

4. The apparatus of claim 3 , wherein the fourth duration is decreased based on determining a synchronized transmission is not received within the first duration of the enabling the circuitry to receive the synchronized transmission.

5. The apparatus of claim 3 , wherein the fourth duration is increased based on the determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

6. The apparatus of claim 1 , wherein the Bluetooth controller further includes instructions to receive synchronized transmissions on a data channel to utilize BLE communication protocols to facilitate connectionless communications.

7. At least one non-transitory computer readable storage medium comprising instructions that, when executed, cause a Bluetooth controller to at least:
enable circuitry to receive a synchronized transmission;
determine if a synchronized transmission is received during a first duration;
increment the first duration to a second duration as a result of not receiving the synchronized transmission during the first duration; and
determine a third duration based on a determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

8. The at least one non-transitory computer readable storage medium of claim 7 , wherein the instructions, when executed, cause the Bluetooth controller to, represent a first reception window as enabling circuitry to receive the synchronized transmission for the first duration, further including a second reception window, the second reception window has a duration equal to the second duration as a result of not receiving the synchronized transmission after enabling the circuitry to receive the synchronized transmission for the first duration.

9. The at least one non-transitory computer readable storage medium of claim 7 , wherein the instructions, when executed, cause the Bluetooth controller to enable the circuitry to receive the synchronized transmission after a fourth duration, and the fourth duration is determined based on the determined difference in time between enabling the circuitry to receive the synchronized transmission and receiving the synchronized transmission.

10. The at least one non-transitory computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the Bluetooth controller to decrease the fourth duration based on determining a synchronized transmission is not received within the first duration of the enabling the circuitry to receive the synchronized transmission.

11. The at least one non-transitory computer readable storage medium of claim 9 , wherein the instructions, when executed, cause the Bluetooth controller to increase the fourth duration based on the determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

12. The at least one non-transitory computer readable storage medium of claim 7 , wherein the instructions, when executed, cause the Bluetooth controller to receive synchronized transmissions on a data channel to utilize Bluetooth Low Energy (BLE) communication protocols to facilitate connectionless communications.

13. A method comprising:
enabling circuitry to receive a synchronized transmission using Bluetooth low energy (BLE) communication protocols;
determining if a synchronized transmission is received during a first duration;
incrementing the first duration to a second duration as a result of not receiving the synchronized transmission during the first duration; and
determining a third duration based on a determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

14. The method of claim 13 , wherein the method further includes representing a first reception window as the first duration, further including a second reception window, the second reception window has a duration equal to the second duration as a result of not receiving the synchronized transmission after enabling the circuitry to receive the synchronized transmission for the first duration.

15. The method of claim 13 , wherein the method further includes enabling the circuitry to receive the synchronized transmission after a fourth duration, the fourth duration is determined based on the determined difference in time between enabling the circuitry to receive the synchronized transmission and receiving the synchronized transmission.

16. The method of claim 15 , wherein the method further includes decreasing the fourth duration based on determining a synchronized transmission is not received within the first duration of the enabling the circuitry to receive the synchronized transmission.

17. The method of claim 15 , wherein the method further includes increasing the fourth duration is based on the determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

18. The method of claim 13 , wherein the method further includes receiving synchronized transmissions on a data channel to utilize BLE communication protocols to facilitate connectionless communications.
