I get an error by using the spectrogram of the mlapp function

[PReit.1]

Hi, I am using a Stwinkt1a and the datalog 1.2.0. In this funtionpack i am using the ReadSensorDataApp.mlapp for visualization. The Time diagram is not the problem but with the spectrogram an error occured, that i quite don't understand.

Thanks in advance

Hi @Philipp Reitenspieß​ ,

did you downloaded the HSDatalog.bin example form the Datalog 1.2.0 function pack on the board, before running the Matlab code?

The predefined firmware for the STWINKT is the FP-IND-PREDMNT1, but I'm not sure it allows a full compatibility with the python / matlab scripts.

Hi @Eleon BORLINI​ ,

i am currently using the HSDatalog.bin from the 1.2.0 function pack. I made a log via BLE Sensors App and then i let the mlapp show the data.

I did this according to the UserManual 2688 and, as seen in the right picture, there is no problem with the time signal. The error occured after pressing the Spectrogram in the bottom left corner.

Hello Philipp,

let me then check with internal experts, and then come back to you.

Hi Philipp,

the spectrogram function is in the Signal Processing Toolbox. Do you have the license for this?

Hi Eleon,

i hope this seems to fix the problem. Honestly it should have been obvious, I only used the toolbox via matlab web application so i need to extend my license on the pc.

Hope this will do it. Thanks for your help.
