I'm testing the LPS22HH on the MKI192-V1 eval board. At normal atmospheric pressure it reports about 1013 hPa, which is what I expect, and it fluctuates over time by a few hPa. It also reports a reasonable temperature value, so I know the I2C interface is working ok. But when I put it in a pressure chamber and adjust the pressure over the sensor's operating range, it still reports about the same pressure within a few hPa even though the actual pressure has changed by several hundred hPa. So it's not responding to pressure changes. I tried this on two samples and got similar results. Has anyone had a similar problem ? Are these sensors damaged or am I missing something ?
