Binary output for Nordic nRF9161 DK + IKS02A1 is not working as expected

Hi All,

I am trying to build a fire alarm detection system by analysing the sound.
For this, I am using the Nordic nRF9161 DK with IKS02A.
I created a public project (585872), used Audio (MFE) as a processing block, and Classification as a learning block.

When I tried to run the model in a web browser, it worked fine. But when I try to deploy the impulse to Nordic nRF9161 DK + IKS02A1 (binary output), its not working. Always showing the same result.

Starting inferencing in 2 seconds…

Timing: DSP 140.000000 ms, inference 16.000000 ms, anomaly 0 ms
#Classification results:
FireAlarm: 0.000000
Noise: 0.996094

Any suggestions/input would be of great help.

Thanks in advance.
