Question/Issue: while uploading the code it’s showing an error on the Arduino Nano 33 BLE SENSE board.

Project ID: 182041

Context/Use case:

I am using Arduino Nano 33 BLE SENSE. I have a project to detect gunshots but it’s showing an error while uploading the code.

ERR: Failed to run DSP process (-1013)

Hello @Tarun.ece,

Can you tell me which DSP block you are using?

The error details can be found here.

If you’re using MFCC, try using MFE instead is you’re using audio. In the meantime, our core engineering team will have a look.

Also, which arduino nano 33 ble sense version are you using?

Best,

Louis

Hi @Tarun.ece,

We updated our SDK last Friday and a bug got introduced with the release.
A fix will be live in the next days on the platform, in the meantime you can either:

  • retrain your model using an MFE block instead of MFCC
  • or, update your Arduino library as shown in this commit → you can find this file usually in the Documents/Arduino/Libraries/*your_project_name*/src/edge-impulse-sdk/classifier
