OBEX Driver:
Exposing the USB Device as a Virtual COM Port!
Overview
The CDC OBEX driver
provides a transport layer by exposing the USB device as a virtual COM port to the host operating system.
The driver can be interfaced with an OBEX stack supporting various OBEX profiles, e.g. File Transfer, Object Push.
Background
The OBEX protocol is designed to transmit data objects between devices.
This protocol was originally developed for infrared data transfers but is being commonly used for
Bluetooth and other various wireless communications.
The protocol is a message oriented but is designed to be layered above TCP-like protocols,
which are character oriented. Therefore, OBEX is implemented using a pair of bulk pipes.
CDC OBEX Driver is a DriverCore Component
The CDC OBEX Driver is a component of the DriverCore product line. DriverCore offers
standard USB Drivers, allowing device manufacturers to expose a variety of native communication interfaces via USB to different operating systems and platforms.
