Hi Alex, t looks like it QNmeaPositionInfoSource reads NMEA strings. I want to output NMEA strings that look like this: $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47 Maybe QNmeaPositionInfoSource has some way to output the raw source strings that it reads? -Ed On Jul

Hi, I am not sure whether this is what you are after but there is a class called QNmeaPositionInfoSource which can take NMEA input from a QIODevice. The QIODevice is supposed to provide the NMEA strings which the API turns into a QGeoPositionInfoSource-like behavior. There is an example for
