Why home icon is flickering, not locked?

Thanks, I have checked GPS_GNSS_MODE, which is using default parameters in module (Maybe altered). It will get around 16 satellites.

@xfacta Do you mean the above log shows hdop is not low or precise enough for Home position lock? I thought HDOP < 1.5(The log shows it’s lower than 1.4 always) is acceptable.

So what might be the key issue here for HOME not locked, I suspect compass, but the mag.health = 1. I don’t understand its behavior right now.
