NMEA sentences can be retrieved from GPS receivers and parsed into a series of coordinates with additional information. Devices without a built-in GPS receiver can retrieve NMEA sentences by using a separate GPS dongle, commonly connected Bluetooth or through a serial port.
1. Find an application such as AT Command Tester that can parse data from the NMEA port.
2. Connect the GPS device over the interface that is supported by the device.
3. Display NMEA GPS data read from the NMEA port.
