I made a couple to changes to the app today.
Race uses GGA NMEA messages so I turn off all other NMEA messages. The app now turns all the NMEA messages back on when exiting.
I noticed that the GPS chip has potential for using SBAS satellites for improved position accuracy. I don't know if the Bangle has the capability or not but the app now issues a $PCAS15,4,FFFF*31 command to turn these satellites on.
