Connecting Eb500 to bx24

I have a breaking head problem. I need to connect my bx24 to Parallax bluetooth eb500, but I've search all over the web and it seems that no one has ever tried that.
I know how to make the physical connection, but I have no idea how to program the bx so it will send data (midi data) to a computer via bluetooth.

PLEASE HELP!!!!!!!!!!

    Pardon my ignorance, but what is BX24? I have sucesfully connected my eb500 to scribbler robot.

    The bx-24 is a microcontroller that works with BasicX, a program very similar to Basic Stamp

    You need max232 level shifter or solder eb500 pin 3 & 4 DIRECTLY to chip, as I did in my recent project

    Yeah, I know how to conect them, but I'm having problems programming the controller in order to send data out using the eb500

    Can you be more specific about your problems?
    • What's exactly not working as you expect it to work?
    • What experiments have you performed already and what are outcomes?
    • What is your code no bx-24, pos it too.

    Regards

    Here is the basicx page with links to most of the files you need www.basicx.com/
    There is also a yahoo group that discusses this chip.

    The BasicX is another 24-pin module made by another company. It is programmed in a Visual Basic looking variant of Basic -- quite different from PBasic. I suggest you ask for this support over there -- very few people on this board will know the Basic variant the BX-24 uses. They can give you LOTS of help connecting the EB500 to a BS2, though.

    You'll have to do the code porting to BasicX yourself.

    Hello Pacits

    I think what you need is http://www.parallax.com/dl/docs/prod/comm/eb500UserManual.pdf
    It is manual about EB500. The fact that EB500 is marketed by Parallax, it is not Parallax specific.
    All you have to do is send to it RX pin specific text (eq "CON" etc.). I have been able to
    user EB500 from PC, Microchip PIC processor and Basic Stamp.

    Good luck
