This app intelligently reads the output from a GPS module. The GPS is connected to the Android device via a TTL/USB converter and an OTG cable.
The app parses the NMEA sentences outputted by the GPS and displays:
. the raw data
. the parameters of interest (lat,lon,speed...)
. the full NMEA sentences
. a map showing current location
The data display is static, unlike when using a USB serial terminal app which will show a scrolling display of the sentences.
Am looking forward to comments and suggestions.
