Data Streamer usable with Bluethooth

Hey,

I'm using an Arduino to send my Sensor Data through the serial connection via USB cable.

Now I'm trying to get a Bluethooth connection from my Aduino Uno (with a HC-05- Module) to Excel Data Streamer instead.

But the Dropdown list for connecting a new Device does not contain something a serial bluetooth connection.

Is anyone willed to help with some suggestions ?

 

Is it even possible ?

 

I would really appreciate your help .

    The BT module is attached to TX and RX on an arduino. it respond to serial.print command just as the monitor and a cable. The setup is straight forward.

    char Incoming_value = 0; //Variable for storing Incoming_value
    void setup()
    {
    Serial.begin(9600); //Sets the data rate in bits per second (baud) for serial data transmission
    pinMode(13, OUTPUT); //Sets digital pin 13 as output pin
    }
    void loop()
    {
    if(Serial.available() > 0)
    {
    Incoming_value = Serial.read(); //Read the incoming data and store it into variable Incoming_value
    Serial.print(Incoming_value); //Print Value of Incoming_value in Serial monitor
    Serial.print("\n"); //New line
    if(Incoming_value == '1') //Checks whether value of Incoming_value is equal to 1
    digitalWrite(13, HIGH); //If value is 1 then LED turns ON
    else if(Incoming_value == '0') //Checks whether value of Incoming_value is equal to 0
    digitalWrite(13, LOW); //If value is 0 then LED turns OFF
    }

    }
