looking for help to get the Arduino Simblee work with pulse sensor!

Projects Programming
1

Hi! I am currently working on an Arduino Simblee Lilypad and a pulse sensor. With a mobile app SimbleeForMobile, I can show the data on my phone, because the Simblee Lilypad supports Bluetooth.
The trouble is the data showed on my phone is not transferred and I don't know how to transfer that! The normal heartbeat should be some number like 90, 80, etc.. But the raw data is like 700+, 600+, etc..
Does anyone have an idea about this? Thanks!

Here is the code:
/*
The sketch demonstrates how to do accept a Bluetooth Low Energy 4
Advertisement connection with the Simblee, then send CPU temperature
updates once a second.

This sketch works with SimbleeForMobile.

Where, exactly, did you stick the probe that is connected to analog pin 3? What kind of device is connected to pin 3? What do those comments have to do with whatever is connected to pin 3? Why is the reading, apparently a temperature, called pulseValue?

  heartbeat = SimbleeForMobile.drawRect(80, 120, 20, 20, rgb(252,135,0), rgb(252,30,0));

I can not, for the life of me, imagine what drawRect() would return, or how that could possibly relate to a heartbeat.
