A method, apparatus, and computer program product provide applications and application developers with generic access from user mode to the L2CAP layer of Bluetooth by exposing the L2CAP layer to user mode via a socket interface. In particular, a kernel mode primary component and user mode helper component cooperate to expose a Winsock interface to user mode components, and to manage various Bluetooth-specific functions and operations, allowing a user mode user application to access Bluetooth functionality without providing Bluetooth-specific commands or actions, and without being required to use RFCOMM.

Bluetooth TDI and winsock interface

A method for providing an interface to a Bluetooth compliant device can emulate a modem such that computer software programs can communicate through the Bluetooth compliant device in the same manner in which they would communicate through a standard modem to access a dial-up, wide area network. The method also supports an interface to a Bluetooth compliant device which can emulate a network socket such that computer software programs can communicate through the Bluetooth compliant device seemingly in the same manner in which they would communicate through a standard network interface card to access a local area network. The method also allows for the interface to a Bluetooth compliant device to be dependent on the nature of the Bluetooth compliant device.

A service discovery stream is represented as an N-ary tree that provides the capability to change, add, or remove an element with only one modification to the entire tree. The number of elements in a stream are counted and each element and the element's children are converted into a node of the N-ary tree. Each node in the tree can have any number of siblings, which are linked to each other using a doubly linked list.

A system and method of Bluetooth compliant architecture and communication uses a miniport driver structure to efficiently implement the Bluetooth protocol layers, while allowing simple communication with underlying hardware.
