GNSS Example

This example, at fixed intervals, will attempt to acquire a GNSS fix to retrieve the current location and time, and print it on the debug console.

 
#include <stdio.h>
#include "flex.h"
 
#define APPLICATION_NAME "GNSS Example"
 
// GNSS FIX Interval
#define GNSS_FIX_INTERVAL_HOURS 6
 
static time_t LocationAndTime(void) {
  time_t time;
  int32_t lat, lon;
 
  if (FLEX_GNSSFix(&lat, &lon, &time) < 0) {
    printf("Failed to get a valid GNSS sync!\n");
 
  } else {
    printf("Lat: %f, Lon: %f, Time: %u.\n", lat * 1e-7, lon * 1e-7, (unsigned int)time);
  }
 
  return FLEX_HoursFromNow(GNSS_FIX_INTERVAL_HOURS);
}
 
void FLEX_AppInit() {
  printf("%s\n", APPLICATION_NAME);
  FLEX_JobSchedule(LocationAndTime, FLEX_ASAP());
}
