Object Exchange Protocol (Windows Embedded CE 6.0)


The Object Exchange Protocol (OBEX) technology for Windows Embedded CE provides an efficient, compact binary protocol that enables a wide range of devices to exchange data spontaneously in a simple, efficient manner.This technology works over Bluetooth and Infrared Data Association (IrDA) protocols.

OBEX is primarily used as a push or pull application.

It performs a function that is similar to Hypertext Transfer Protocol (HTTP) but it does not require the resources that an HTTP server requires. This makes OBEX perfect for low-end devices with limited resources.
