Indoor location with no internet connection

Is is possible to use indoor location with no internet connection at all. Possibility to save Location and beacons etc locally to be able to navigate/show where you are?

Yup! You can use the Location Builder to generate a floor plan entirely on the device.

Just follow this guide:

… and simply skip the last step, “uploading to Estimote Cloud”, and instead, you can use the “location” object directly to start position updates.
