The probe read also covers direct pressure reads. > I'm a bit lost. So how stale can it be in the direct pressure read case? One temperature period, so 1 s at the default 1 Hz. A direct pressure read takes new temperature result whenever TMP_RDY is set. Probe read is for a pressure read that comes before first temperature result after probe. That one would use temp_raw = 0.
