File Transferring via BlueTooth Based on the Obex Protocol

In this paper, any type of files could be transferred via Bluetooth between Windows Mobile-based devices which should have Obex support. The Microsoft supplies COM interfaces for developer to use the obex protocol, so the paper primarily uses the obex interface to implement the file transferring. The OBEX protocols enable synchronous and asynchronous device discovery for Windows Mobile-based devices. This article takes use of asynchronous device discovery, so that application uses fewer system resources than synchronous device discovery. In order to send the file, it needs the path of files stored in the device.
