let's assume there's a mobile device which has an internal gps and an external bluetooth GPS attached to it. Certaily, the B-GPS gives much more accurate location coordinates than the internal GPS. So I'd like to use the B-GPS on my application. It seemed that choosing a positioning method is performed by Applicatoins->Location->Positioning->Positioning Methods->(Enable/Disable) to me a long time ago. However as I read acquisiton API, it seems that I have to set up which module will be used in codes manually.
which is right?
Would you let me know how to choose a positioning method so as to my application can acquire latitude and longitude which are more accurate?
