nobody is not know anything about that :S
If you keep saying that, people aren't going to bother answering you in future. If people had ideas, they would say so. People have already given you answers, but you rejected them.
You can't just 'send a file to any device'. At the very least, assuming you find a phone willing to accept your attempt to connect, you need *something* on the other phone that is capable of accepting a file. Do you know what application on the target phone you are hoping to use, if not yours? You need to know its protocol, so that you can use it to correctly transmit the file. Why *can't* your app be on the target phone? It would probably make it a lot easier.
What you are asking sounds dangerously like you want to spam people's phones (any within range) with unwanted files, so a quick explanation of *why* you want to do this might get a better response. Describe the application you have in mind - people might be able to suggest alternative ways.
