Hi guys

Recently I'm trying to code something special in android for Bluetooth connection.
But from what I found in Internet, it seems that there no simple answer to this question.
So I thought to ask it here, maybe someone knows something that I couldn't find in Internet.

Here is my problem:
I want to send data broadcasts via Bluetooth, so people near my device receive that data if they are listening for such broadcast(exactly like wired network broadcasting, but with Bluetooth).
I don't want to search for nearby devices and connect them one by one if possible, but specially I don't want pairing(will not be funny that everone need to pair with a local area messaging device)
Do you think is it possible to this?

On another question, will similar thing be possible via wireless?

Regards

It will be up to the people who want to receive the broadcast to link to the device id.
As far as I know there is no way to initiate a bluetooth connection any other way.
I suppose you could hijack an active connection. I have no idea how.

Do I understand you correctly ?

I just wanted that sender does not need to create a p2p connection to other devices to send data 1 by 1.
But if there is no way for it, at least I don't like that receiver need to pair with sender to receive that data.

Maybe you could "push" the data ?

haha..
do you mean OBEX?
I thought myself too. I didn't see any limitation for pairing in OBEX, but it seems android has applied its own limitations for obex.
I may try to go through OBEX too.
btw, any idea that this approach is possible for wifi?

Regards

I dont see any reason why obex over wifi wont work.
It may not be simple but you dont need to be paired.
