 ## Overview
-The DR_NMEA application is engineered to improve GPS data accuracy by using dead reckoning techniques. It processes and refines NMEA sentences to deliver reliable latitude and longitude readings, even in environments with weak or absent GPS signals.

 4. **SDK Appdata Group-Level Editing:**
-   - If you are editing SDK Appdata at the group level, it is advised to create an entry in SDK Appdata named `"DR_NMEA"` at the group level *before* deploying the app to devices. This ensures that the app does not write default settings to the device configuration, which would override the group settings.
