    To make the module as a transmitter and transmit music, you need to type the following commands:

    SET PROFILES=ON 0 1 0 1 1 1 1

    WRITE

    RESET

    This puts the module in transmit mode and resets it in transmit mode.

    Then you have to put your headset in Pairing mode and type the following command.

    INQUIRY 5 (or more if needed for example INQUIRY 10)

    The board will list the headset devices it will find.

    then you need to Pair and Open the connection.

    PAIR <Bluetotoh Address>

    OPEN <Bluetoothe Address> A2DP

    Please see the log below where I connected to a JBL headset.

    You have to connect a Line-In Audio source in the 3.5mm Jack and the Jumper as per the DISKIT diagram. You will hear the Audio in the headset.
