Software Usage

  • Use serial to read raw data, tutorial here: RPI UART, please make sure login shell on uart is turned off
  • Data output example:
$GPTXT,01,01,01,NMEA unknown msg*58
$GPTXT,01,01,01,NMEA unknown msg*58
$GPTXT,01,01,01,NMEA unknown msg*58
$GPRMC,,V,,,,,,,,,,N*53
$GPVTG,,,,,,,,,N*30
$GPGGA,,,,,,0,00,99.99,,,,,,*48
$GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30
  • recommanded GPS parsing application GPSD
