I don't see a huge problem here.
Why not just parse whatever message with interesting info we get?
if (!strcmp("$GPGLL") { // extract coordinates and update buffer } else if(!strcmp("$GPGGA)) { // extract coordinates and update buffer } else if(!strcmp("$GPRMC)) { // extract coordinates and update buffer } else if(!strcmp("$GPSuperProprietaryMessageWithAwesomePrecisionData")) { // extract coordinates and update buffer } else { // no luck with this message return; }
I agree with this approach. I think that is scales well if a new device (even not nmea) wants to be supported.
how about a proper gpsd-integration? I've some spare time in the end of this month to try it. I would parse only one least common NMEA-sentence. As Mad said the "GPRMC"-sentence should be a good candidate for this. All other GPS-input-messages could be read via libgpsd from gpsd (which seems to be able to read even most obscure GPS-binary formats).
