I see that it's possible to use an external GPS connected via Bluetooth to gather more accurate GPS coordinates.
But I don't know how to program my XLSform or Xform to do this.
Can someone please help me?
Thank you in advance!!!
There is nothing to program in the form. If you have an external GPS connected via Bluetooth and Android can see it as the primary GPS, ODK Collect will use it.
