Problem using SDP31 differential pressure sensor

Other
1

I have connected a SDP31 differential sensor to my IoT 9DoF logger board which does detect the sensor OK. The logger is connected via USB to my PC running Teraterm.

Initially the readings from the sensor are a scrolling list of:

-9999.000
-9999.00
etc

After configuring the sensor to output pressure Pa and no temperature correction the sensor provides meaningful differential pressures. However, after saving these settings and then re-starting the loT 9DoF the readings revert to -9999.00, etc.

I have tried everything but the problem remains. Any suggestions?
