Default example for Asset Tracker GPS prints erratic NMEA sentences to serial

I suspect the problem is that reading from Serial1 isn’t happening in a tight loop while characters are available. I have an example here that demonstrates a better read loop that should handle the extra data better:

github.com

dmiddlecamp/fancy-asset-tracker/blob/master/gps-clock/main.ino#L51-L63


while (mySerial.available()) {
    char c = GPS.read();


    // lets echo the GPS output until we get a good clock reading, then lets calm things down.
    if (!hasGPSTime) {
        Serial.print(c);
    }




    if (GPS.newNMEAreceived()) {
        GPS.parse(GPS.lastNMEA());
    }
}

Thanks,
David
