Hi, i am using the ST BLE App with a STWIN Starter Kit. The video on the homepage shows the possibility to see the live data and fft analysis. I don't get this in the usage of the app. Can someone please give me a short introduction or show me the manual?

Hi, in this video (https://www.youtube.com/watch?v=J3M0_9EdOqU) they use the FFT amplitude window by clicking on the top left of the page and selecting FFT Amplitude from the menu.

Is this what you are looking for?

Hi, this is exactly the video i was talking about. I made a screenshot, to show you my screen. I just can't find this option.

Maybe it is the usage of the wrong binary. With the BLE_sanpleapp binary i only got temprature, pressure etc.

Which one is the right one for this application?

uhm the app is changed meanwhile.

Try with the example bin in the FP-IND-PREDMNT1 (https://www.st.com/en/embedded-software/fp-ind-predmnt1.html), it is the default firmware and should activate the FFT .

Thanks for putting it beside. I only got the actual version v2.4.0 from the website, which doesn't seem to support the STM32L4R9ZI or at least i cannot get aconnection via bluetooth.

At the beginning i got a few refreshing graphs, but than it seems to stop ot of a sudden. The plot function also seems to show no graph. Is it the version, the app or even me?
