Abstract

Aspects of a method and system for multiple HCI transport for Bluetooth® Host controllers may include communicating between a plurality of Bluetooth® hosts and a single Bluetooth® host controller by using one or more Bluetooth® host controller interfaces. Control of the Bluetooth® host controller interfaces may be assigned to one or more of the Bluetooth® hosts. Control of the Bluetooth® host controller interfaces may be switched among different Bluetooth® hosts using various protocol commands may be used to communicate between Bluetooth® hosts to control switching. Communications between Bluetooth® hosts may occur over interfaces different from the Bluetooth® host controller interfaces. Switching may occur without resetting the Bluetooth® hosts and Bluetooth® host controller.

Claims

1. A method for processing signals in a Bluetooth®

system, the method comprising;

communicating between a plurality of Bluetooth®

hosts and a single Bluetooth®

host controller via one or more Bluetooth®

host controller interfaces.

2. The method according to claim 1, comprising assigning control of said one or more Bluetooth®

host controller interfaces to one or more of said plurality of Bluetooth®

hosts.

3. The method according to claim 2, comprising switching control of said one or more Bluetooth®

host controller interfaces among different ones of said plurality of Bluetooth®

hosts.

4. The method according to claim 3, comprising controlling said switching via one or more protocol commands.

5. The method according to claim 4, comprising communicating by said one or more protocol commands between said plurality of Bluetooth®

hosts.

6. The method according to claim 5, wherein said controlling of said switching occurs over one or more interfaces that are different from said one or more Bluetooth®

host controller interfaces.

7. The method according to claim 3, wherein said switching occurs without resetting of said plurality of Bluetooth®

hosts and said Bluetooth®

host controller.

8. A system for processing signals in a Bluetooth®

system, the system comprising;

one or more Bluetooth®

host controller interfaces that enable communication between a plurality of Bluetooth®

hosts and a single Bluetooth®

host controller.

9. The system according to claim 8, wherein said plurality of Bluetooth®

hosts assigns control of said one or more Bluetooth®

host controller interfaces to one or more of said plurality of Bluetooth®

hosts.

10. The system according to claim 9, wherein said one or more of said plurality of Bluetooth®

hosts switches control of said one or more Bluetooth®

host controller interfaces among different ones of said plurality of Bluetooth®

hosts.

11. The system according to claim 10, wherein said one or more of said plurality of Bluetooth®

hosts controls said switching via one or more protocol commands.

12. The system according to claim 11, wherein said plurality of Bluetooth®

hosts communicates by said one or more protocol commands among said plurality of Bluetooth®

hosts.

13. The system according to claim 12, wherein said one or more of said plurality of Bluetooth®

hosts controls said switching via one or more interfaces that are different from said one or more Bluetooth®

host controller interfaces.

14. The system according to claim 10, wherein said plurality of Bluetooth®

hosts enables said switching without resetting said Bluetooth®

host controller or any of said plurality of Bluetooth®

hosts.

15. A machine-readable storage having stored thereon, a computer program having at least one code section for processing signals in a Bluetooth®

system, the at least one code section being executable by a machine for causing the machine to perform steps comprising;

communicating between a plurality of Bluetooth®

hosts and a single Bluetooth®

host controller using one or more Bluetooth®

host controller interfaces.

16. The machine-readable storage according to claim 15, comprising assigning control of said one or more Bluetooth®

host controller interfaces to one or more of said plurality of Bluetooth®

hosts.

17. The machine-readable storage according to claim 16, comprising switching control of said one or more Bluetooth®

host controller interfaces among different ones of said plurality of Bluetooth®

hosts.

18. The machine-readable storage according to claim 17, comprising controlling said switching via one or more protocol commands.

19. The machine-readable storage according to claim 18, comprising communicating by said one or more protocol commands between said plurality of Bluetooth®

hosts.

20. The machine-readable storage according to claim 19, wherein said controlling of said switching occurs over one or more interfaces that are different from said one or more Bluetooth®

host controller interfaces.

21. The machine-readable storage according to claim 17, wherein said switching occurs without resetting of said plurality of Bluetooth®

hosts and said Bluetooth®

host controller.
