Resolved! For the IIS3dWB ODR and sampling rate...

I need to confirm what the ODR represents - the default ODR is 26667Hz. But what is the actual internal sample rate pre anti-aliasing filter (which must be implemented internally)?Assuming the actual Fsample is at least 26667, then ODR simply represe...

Hello, I'm working with STEVAL-STWINKT1B kit and the latest version of FP-SNS-DATALOG1 sw package. I'm trying to set the ISM330DHCX 's ODR to 208 samples/s but in this case the acquisitions are corrputed. Is there any known bug?

The ODR is set by modifying the DeviceConfig.json file.Only the ISM330DHCX acquisition is corrupted.By debugging the code seems that the problem could be about the calculation of parameter "sdwritebuffersize" in function "SDM_CalculateSdWriteBufferSi...
