Hello, we are enountering problems with BMP390 sensor during a fast movements. When sensor is stationary, drift is relatively small - just meter or so during a few minutes. But when we are doing fast movements up and down periodically measurement has incremental offset with each "down" movement. Up and Down movement is same, in range for around +/- 0.5 meter. When we are moving with PCB by hand, not touching the sensor or anything from the electronics, after lets say 20 up and down movements we are + 10 meters in offset. This offset will remain indefinitively. Interestingly we have BME280 in our other device and this offset does not happen. We tried several batches of BMP390 and the problem is happening with all of them. Can you let me know what could be wrong? We tried all possible oversampling and filter settings with no improvement. There is absolutely no light that could interfere with sensor. Also when sensor is cold and we will start device, it seems that temperature compensation does not work properly, because it can drift by 30 meters once it stabilizes within 2 minutes.
