Hi, Tony White!
Thanks for the reply! Yeah, I know the Navigator is top-tier, but I was thinking of a Pixhawk-style board.
So on the temperature issue: SCALED_PRESSURE/temperature shows 64°C, and SCALED_PRESSURE2/temperature shows 48°C. Pretty sure those are the internal controller temps.
The physical baro sensor is actually at room temp (~23°C). I tested it directly with the Arduino library and it was fine.
I should note, the baro info wasn’t even showing up until I tweaked some parameters from their default values.
