Abstract

The present invention relates to the field of wireless audio streaming. The invention can be used to manage dynamically the configuration of a link between a Bluetooth audio source and a Bluetooth audio sink, or between a master and slave device. The invention relates to method for operating a Bluetooth device, the method comprising: transporting audio information over a Bluetooth communication link established with a second device; determining, upon a change of value of an operational parameter in either the Bluetooth device or the second device, a new operating mode for said Bluetooth communication link; modifying a configuration parameter of said Bluetooth communication link based on the new operating mode; transporting audio information on said Bluetooth communication link according to the modified configuration parameter.

Claims (56)

1 . A method for operating a Bluetooth device, the method comprising:

transporting audio information over a Bluetooth communication link established with a second device;

determining, upon a change of value of an operational parameter in either the Bluetooth device or the second device, a new operating mode for said Bluetooth communication link, wherein the operational parameter is a launch of a gaming application;

modifying a configuration parameter of said Bluetooth communication link based on the new operating mode; and

transporting audio information on said Bluetooth communication link according to the modified configuration parameter.

2 . The method of claim 1 , wherein the operational parameter is associated with an operating system running on the Bluetooth device or the second device.

3 . The method of claim 1 , wherein the operational parameter is associated with an application running on the Bluetooth device or the second device.

4 . The method of claim 1 , wherein the modifying of the configuration parameter is performed by a Bluetooth Host.

5 . The method of claim 1 , wherein the modifying of the configuration parameter is performed by a Bluetooth Controller.

6 . The method of claim 1 , wherein the configuration parameter is one of:

an audio configuration parameter, or

a Bluetooth connection parameter.

7 . The method of claim 6 , wherein the configuration parameter is one audio configuration parameter among:

a type of codec,

a parameter relative to a codec,

a type of data,

an audio channel selection parameter, or

a sampling rate parameter.

8 . The method of claim 6 , wherein the configuration parameter is one Bluetooth connection parameter among:

a Flush Timeout parameter,

a channel type parameter,

a quality of service parameter,

a number of retransmission parameter,

a parameter among BLE link parameters,

a packet type parameter, or

a Maximum Transmission Unit (MTU) parameter.

9 . A Bluetooth device comprising a Bluetooth chip, a processor and a memory configured to:

transport audio information over a Bluetooth communication link established with a second device;

determine, upon a change of value of an operational parameter in either the Bluetooth device or the second device, a new operating mode for said Bluetooth communication link, wherein the operational parameter is a launch of a gaming application;

modify a configuration parameter of said Bluetooth communication link based on the new operating mode; and

transport audio information on said Bluetooth communication link according to the modified configuration parameter.

10 . The Bluetooth device of claim 9 , wherein the operational parameter is associated with an operating system of the Bluetooth device or the second device.

11 . The Bluetooth device of claim 9 , wherein the operational parameter is associated with an application running on the Bluetooth device or the second device.

12 . The Bluetooth device of claim 9 , further comprising a Bluetooth Controller and wherein the modifying of the configuration parameter is performed by the Bluetooth Controller.

13 . The Bluetooth device of claim 9 , wherein the configuration parameter is one of:

an audio configuration parameter, or

a Bluetooth connection parameter.

14 . The Bluetooth device of claim 13 , wherein the operational parameter is one audio configuration parameter among:

a type of codec,

a parameter relative to a codec,

a type of data,

an audio channel selection parameter, or

a sampling rate parameter.

15 . The Bluetooth device as set forth in claim 13 , wherein the operational parameter is one Bluetooth connection parameter among:

a Flush Timeout parameter,

a channel type parameter,

a quality of service parameter,

a number of retransmission parameter,

a parameter among BLE link parameters,

a packet type parameter, or

a Maximum Transmission Unit (MTU) parameter.

16 . A non-transitory, computer-readable storage medium, having stored there on a computer program comprising program instructions, the computer program being loadable into a data-processing unit of a first device and adapted to cause the data-processing unit to carry out a method comprising:

transporting audio information over a Bluetooth communication link established with a second device;

determining, upon a change of value of an operational parameter in either the first device or the second device, a new operating mode for said Bluetooth communication link, wherein the operational parameter is a launch of a gaming application;

modifying a configuration parameter of said Bluetooth communication link based on the new operating mode; and

transporting audio information on said Bluetooth communication link according to the modified configuration parameter.
