http://code.google.com/p/amarino/downloads/detail?name=SensorGraph_02.zip must work the problem there was this. We should've done this-

int sensor=A5 //pin name for Bluetooth TX to the ARDUINO RX
in the loop
void loop()
{
Serial.begin(9600);
}

 Never realized that this was to send the data value from arduino to android. Sry.
Tomorrow, am writing and understanding the code of the amarino app from the thesis for six hours 6:30 to 12:30. By 1:00 will leave for home. By 3:30 will start unit 3.

to configure your bt module you have to connect rx to rx and tx to tx, then you can use the serial monitor to turn your bt into command mode ($$$).

in normal operation mode pins must be rx to tx and tx to rx.
