Some issues with Arduino Nano 33 BLE Sense

Hey all! I’m a real newbie to the whole scene, and currently working on a project to detect crying infants.


My issue is that after uploading the sketch to the Arduino, I get the following errors 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.

I’m not sure if it’s relevant, but when I run the edge-impulse-daemon, I see the following errors repeated over and over as well:

[SER] Serial is connected, trying to read config…
[SER] Failed to get info off device Timeout when waiting for > (timeout: 5000) onConnected

Project ID:

Project ID 194801

Context/Use case:

Not sure what to put for Context/Use case

If anyone can offer any help, I’d appreciate greatly.


Are you using a Rev 2 Arduino Nano board?

Yes, it’s the Rev2 board, which I recently noticed is not yet supported by Edge Impulse.

I did however get it to work when I used the bootloader, so still not sure what’s causing the issue.

how dd you use the bootloader? i am also trying to get this board to work with microphone
