[gpsd-users] Gps application stops transmitting data after some time

[lokesh kumar Nijalinge]

Hi All,

I am trying to write the gps application code using gpsd library. The below code i got after searching internet. This works fine, but after some time the data stops coming.

Can anyone let me know if something is missed in this part of code.

Below is the code

if ((rc = gps_open("localhost", "2947", &gpsdata)) == -1) {
    printf("code: %d, reason: %s\n", rc, gps_errstr(rc));
    return EXIT_FAILURE;
}
gps_stream(&gpsdata, WATCH_ENABLE | WATCH_JSON, NULL);

while (1) {
    /* wait for 2 seconds to receive data */
    if (gps_waiting (&gpsdata, 2000)) {
        /* read data */
        if ((rc = gps_read(&gpsdata)) == -1) {
            printf("error occured reading gps data. code: %d, reason: %s\n", rc, gps_errstr(rc));
        } else {
            /* Display data from the GPS receiver. */
            if ((gpsdata.fix.mode >= MODE_2D) && !isnan(gpsdata.fix.latitude) && !isnan(gpsdata.fix.longitude)) {
                if(!isnan(gpsdata.fix.time))
                        (void)unix_to_iso8601(gpsdata.fix.time, scr, sizeof(scr));
                    printf("latitude: %f, longitude: %f, speed: %.1f %s, timestamp: %s altitude: %f climb %.1f %s/min \n", gpsdata.fix.latitude, gpsdata.fix.longitude, gpsdata.fix.speed * speedfactor, speedunits, scr, gpsdata.fix.altitude, gpsdata.fix.climb * altfactor * 60, altunits);
            } else {
                printf("no GPS data available\n");
            }
        }
        printf(" Wait ");
    }
    sleep(1);
        printf("status %d \n",gpsdata.status);
}

Thanks,
