FFT compare function on SensorTile.Box PRO

[francus76]

Good Morning,

I own both a SensorTile.box and a SensorTile.Box PRO. I used the SensorTile.box to identify anomaly vibrations on a device, using the prebuilt app, with slight modifications, that performs the FFT of data coming from the accelerometer and then the FFT Compare with the reference FFT captured when no anomaly is present on the device. Now, due to some limitations of the SensorTile.box, I want to replicate it on the SensorTile.box PRO, but among the available functions offered to manipulate data, there is only FFT (DFT - Discrete Fourier Transform), but not the FFT Compare which is available on the base board. 

The question is: how can I recreate the app developed on SensorTile.box to operate also on the SensorTile.Box PRO? Do I need any firmware upgrade and if yes, where I can download it? It seems to me very strange a so important function is not present and I don't think it could be difficult to insert it also on this device.

Could someone share with me the firmware upgrade that could enable such functionality?

Thanks,

Francesco

Hi @francus76 ,

The FFT comparison feature is not yet available on Sensortile.Box PRO, even as a flow example. 

Sorry about that, we are working on reintroducing the feature in Sensortile.box PRO.

Thanks Federica.

Is there a planned date for the reintroduction of this functionality in SensorTile.Box PRO?

Hi @francus76,

We don't have a definite date but I will update you as soon as it is released.

Hello @Federica Bossi ,

we should schedule a deploy session with a client and, due to the problems found with SensorTile.Box when connected to a Raspberry via USB (at every power down or electricity disconnection any expert mode app needs to be manually re-uploaded), we would like to switch to SensorTile.Box PRO, which doesn't have this limitation.

However, as previously mentioned, we need to use on the SensorTile.Box PRO the same "FFT compare" function that is present on the the SensorTile.box. 

Can I ask if I can expect, in a relatively short timeframe, that a new SensorTile.Box PRO firmware will be released with this function in the Expert Flow mode? 

If any update will not be released in the current/start of next month, is it possible to have a previous firmware version where the FFT compare was present? (since you talked about "reintroducing the feature" I assumed that it was present in a previous firmware version).

Thanks,

Francesco
