Using BMX055

[shruthi8]

I'm working on a project which needs a magnetometer to face the north direction. I'm using the BMX055 sensor to achieve the values. In order to do this, I need to determine mainly two values i.e. direction I'm facing and the angle.
I've looked at a couple of references, but could not find anything. The raw values on the magnetometer do not seem consistent and when I return to a different position, I always get similar x,y,z raw values as obtained in the previous position itself which will be varying continuously. Even if I'm trying to calibrate my sensor it is not working. Please guide me for the same.

Thanks for any input.
