Computer system and method thereof for bluetooth data sharing between UEFI firmware and OS

1. A computer implemented method comprising:

initiating power on mode in order to execute UEFI firmware for OS boot up procedure;

initiating, by utilizing the UEFI firmware, pairing with a Bluetooth device;

saving, by utilizing the UEFI firmware, a pairing connection data of the Bluetooth device to memory in an operating system readable form; and

retrieving, by utilizing an operating system, the pairing connection data saved in the operating system readable form by the UEFI firmware during a period that the operating system initiates hardware detection and proceeds to install and/or execute corresponding drivers, to allow the operating system determine which drivers to match to the Bluetooth device according to the pairing connection data and automatically re-pair the Bluetooth device to the computer system according to the pairing connection data.

retrieving the ACPI table from the memory via a OS Bluetooth driver under the Operating System environment; and

initiating connection to the Bluetooth device with the OS Bluetooth driver based on the connection information in the ACPI table.

5. The method of claim 1 , further comprising:

generating a SMBIOS table as the pairing connection data; and

saving the SMBIOS table to memory.

6. The method of claim 5 , further comprising:

building the SMBIOS table via UEFI Bluetooth driver by transforming connection information of the Bluetooth device into the SMBIOS table.

7. The method of claim 6 , further comprising:

retrieving the SMBIOS table form the memory via a OS Bluetooth driver under the Operating System environment; and

initiating connection to the Bluetooth device with the OS Bluetooth driver based on the connection information in the SMBIOS table.

8. The method of claim 1 , further comprising:

generating a UEFI variable as the pairing connection data; and

saving the UEFI variable to memory.

9. The method of claim 8 , further comprising:

creating the UEFI variable via UEFI Bluetooth driver by transforming connection information of the Bluetooth device into the UEFI variable.

10. The method of claim 9 , further comprising:

retrieving the UEFI variable from the memory via a OS Bluetooth driver under the Operating System environment; and

initiating connection to the Bluetooth device with the OS Bluetooth driver based on the connection information in the UEFI variable.

11. A Computer System comprising:

a memory; and

computer-readable instructions stored at the memory and executable by a microprocessor to:

initiating power on mode in order to execute a UEFI firmware for OS boot up procedure;

initiating, by utilizing the UEFI firmware, pairing with a Bluetooth device;

saving, by utilizing the UEFI firmware, a pairing connection data of the Bluetooth device to memory in an operating system readable form; and

retrieving, by utilizing an operating system, the pairing connection data saved in the operating system readable form by the UEFI firmware during a period that the operating system initiates hardware detection and proceeds to install and/or execute corresponding drivers, to allow the operating system determine which drivers to match to the Bluetooth device according to the pairing connection data and automatically re-pair the Bluetooth device to the computer system according to the pairing connection data.

12. The computer system of claim 11 , wherein the instructions are further to:

generating an ACPI table as the pairing connection data; and

saving the ACPI table to memory.

13. The computer system of claim 12 , wherein the instructions are further to:

building the ACPI table via UEFI Bluetooth driver by transforming connection information of the Bluetooth device into the ACPI table.

14. The computer system of claim 13 , wherein the instructions are further to:

retrieving the ACPI table from the memory via a OS Bluetooth driver under the Operating System environment; and

initiating connection to the Bluetooth device with the OS Bluetooth driver based on the connection information in the ACPI table.

15. The computer system of claim 11 , wherein the instructions are further to:

generating a SMBIOS table as the pairing connection data; and

saving the SMBIOS table to memory.

16. The computer system of claim 15 , wherein the instructions are further to:

generating a UEFI variable as the pairing connection data; and

saving the UEFI variable to memory.

17. The computer system of claim 16 , wherein the instructions are further to:

building the SMBIOS table via UEFI Bluetooth driver by transforming connection information of the Bluetooth device into the SMBIOS table.

18. The computer system of claim 17 , wherein the instructions are further to:

retrieving the SMBIOS table form the memory via a OS Bluetooth driver under the Operating System environment; and

initiating connection to the Bluetooth device with the OS Bluetooth driver based on the connection information in the SMBIOS table.

19. The computer system of claim 11 , wherein the instructions are further to:

generating a UEFI variable as the pairing connection data; and

saving the UEFI variable to memory.

20. The computer system of claim 19 , wherein the instructions are further to:
