With a DLPF of 62.5 Hz, the sampling rate is apperently not 1 kHz anymore, because the driver got duplicate samples and published only at 128 Hz. We have to increase the filter back to 500 Hz so that we get 1 kHz sampling rate, with 250 Hz publications.

FYI - this will be one of the first IMUs updated to disable the DLPF, grab all raw data using the FIFO and SPI DMA, then filter entirely PX4 side. At this point simply waiting for #11570 (which is waiting for v1.9.0 to go out). |

#11434 wasn't quite right.
With a DLPF of 62.5 Hz, the sampling rate is apparently not 1 kHz anymore,
because the driver got duplicate samples and published only at 128 Hz.
We have to increase the filter back to 500 Hz so that we get 1 kHz sampling
rate, with 250 Hz publications.
