DIY GPS data format?

I'm starting a project to build in a GPS onto my bike so I don't have to mess with a GLO anyone. What GPS message format does RaceChrono expect? I saw there is a great thread with RC3 format information, but I haven't seen equivalent for GPS




    RaceChrono needs either combination of $GPGGA/$GPRMC or $GPRMC/$GPZDA/$GPVTG
  • Perfect, thank you!
  • Most of the GPS chips will output in NMEA format, so it might be that all you need to do is to re-route the data over Wi-Fi or Bluetooth.
  • That's the plan...

    I've managed to get some GPS data to pass through to serial. I'm debugging a bad string though. And I've managed to get a bluetooth connection... so debugging then put it all together! It sounds so easy
  • Just to verify, RaceChrono only logs RC3 acceleration data, correct? It isn't used for any GPS augmentation or correction?
  • @ManMan, that's correct
