USB CDC OBEX (DriverCore Component)

DriverCore » 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.
