NMEA-0183 Stromovka

stromovka-060615-2015.nmea (123kB) — NMEA file of one potential route. The route corresponds to the attached picture:

bool isChecksumValid(char *ptr)
{
  if(*ptr++ != '$')
    return false;

  char sum = 0;
  for( ; *ptr != '*' && *ptr != '\0'; ptr)
    sum ^= *ptr;

  if(*ptr != '*')
    return false;

  if(strlen(ptr) < 2)
    return false;

  int check;
  if(sscanf(ptr, "%02X", &check) != 1)
    return false;

  return ((unsigned char)sum == check);
}
