Hi, in the ST BLE App, how to choose the right acquisition time in the FFT setting for ism330dhcx vibration sensor? Please advise. Thanks!

Hi, it depends on your application, but it seems that the ST BLE App is limited to 1024 samples, so you can configure the 6667Hz ODR but you have a limitation on the sample rate. SO maybe 3333Hz are enough to exploit all the FFT band.

Hi @JTam.1 ,
you might refer to this white paper, that explains a bit how to choose FFT parameters in general.
