Use Arduino BLE 33, to test still angle of it

Help
#1

Question/Issue: I’m new to ML. Tried test put BLE 33 in 4 different position, 0, 45, 90, 180 degree to flat table surface. Each angle tried 20, so total 80 samples. Go through all the process to get a model. But the result is quite bad. From my side, it looks so obviously x,y,z value, but why the result is so bad? What I did wrong?

Thank you !

Hi @jy3023,

This project doesn’t seem to exist. Have you deleted it by chance?

Hi Aurel, I see the project still there and made public. Project Name: angle_ble
, Project ID 135606

@jy3023,

Found it (it was 135605 actually). I see that you are using a spectral features block but your data is constant, no specific frequency can be extracted from your samples.
I would suggest using a Raw or Flatten block instead.

Thank you Aurel, seems my project is lost, I can not see it anymore in my dashboard, please help. thank you!

#6

Strange, it is still in your list of projects. Can you try this direct link?

#7

Thank you Aurel, everything works well now.

Hi Aurel, I tried Flatten block, but the result is still not nice, could you help to check, thanks

Hi Aurel, is there you see anything I did wrong, or this type of application is not good for machine learning? Thanks

I still see the spectral features in your project. Can you point me out to your project with the Flatten block? Also can you try with the Raw block as well?
