Arduino Nano 33 BLE Sense Rev2

Hello, I am very new to all of this so please have patience with me!
I am working on a project to use classification for baby noises using Arduino Nano 33 BLE Sense Rev2. I’ve created my impulse/model and have connected the board to Arduino IDE, but during deployment process, I keep receiving an error in the Arduino IDE’s serial monitor:

ERR: Failed to run DSP process (-1013)
ERR: Failed to run classifier (-5)

These repeat over and over again.

The process works fine when just choosing microphone, but when doing microphone continuous, the problem occurs. I’ve made my model smaller and more simpler incase it was a RAM issue, but it still did not work. Total data is only around 3-4mins.
I suspect that this might be because the rev2 version of the board is not supported…? Still hoping that there might be a way.

Project ID 198967

Any help is appreciated.

Thank you!

  • I am so sorry for your frustration with the EI Studio and the Arduino Nano 33 BLE Sense Rev2.
  • (Imagine my frustration with answering this for the umpteenth time.)
  • EI is working on an update with a release date of TBD.
  • In the mean time see this.

Hello @babybot,
