Transferring files using Bluetooth

[Banupriya]

Hi All,

Is it possible to transfer files from PC to Mobile(BT faciliated Mobile) vice versa without using Bluetooth Dongles/adapter?

Is it possible through Programming?

Is any programming needed, While using Bluetooth adapter?

Thanks

hi,
if u want to send file b/w two devices they should ve bluetooth enabled.
A pc may ve bluetooth usb adapter or some other bluetooth device.
And every bluetooth device has some profiles(services) like file transfer,obex(object exchange) etc..
so u need not write any code for sending the files.the manufacturers ll provide those with driver.

Then can any one temme Why this program is for?

ragesh, could you ask your question in more detail? Which programming language and device do you want to use?
