I have been using your Edge Impulse platform so far. It has been awesome. I recently built an audio recognition system with two classes which worked well. However, when I increased my data class to 4, I got the following error:
Failed to load
Classification failed(err code: -3)
Hey @George_i, I just did a quick test on your project and I can classify data… How long is the sample that you’re uploading? And does it show up afterwards in the list of samples under ‘Live classification’? If so, could you leave it there and not remove the sample? That would let me check what might be going on.
I have the same issue. My code works really fine with 3000ms window size, however even though I tried to reduce it 1000 ms I have same classification error both in my phone and in Arduino BLE 33 Sense. What should I do?
Thanks in advance.
Arduino Ble 33 Sense also gives this error: Classification error (-5) as my mobile phone gives for my project named CoughDet2. Its window size is 3000 ms. When I try for my Selinay-Project1 named project with a window size 2000ms it is working.
