Transfering data from a sensor to the iphone
<p>I have an external device (some kind of sensor) that can do a measurment. This sensor can be connected to a PC via Bluetooth or USB cable, and it also comes with its own software.
I want to develop an app for iphone that will analyze the data that this sensor is measuring (for example creating a graph, calculating some equations etc.).
How can i make my iphone to "recognize" this sensor, so the app will get the data that has benn measured from the sensor? 
is there any manual which explain how to code this? our preffered way of transfering the data is via Bluetooth, so there will be no need of using cables.</p>

<p>Thanks a lot,
Or.</p>
