Thread: Bluetooth, Android, and nothing more!

    Bluetooth, Android, and nothing more!

    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
    I should look out my posts,Or JMI will get mad at me! ;)

    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?

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