We did some bug fix a few weeks ago on a similar issue. Is your Arduino library recent? You could try to generate it again. Also we tested the image recognition on the BLE Sense using a MobiletNet v1 0.25 model, might be worth giving it a try.
The embedded team is also investigating the issue in parallel.
Thank you again for the quick follow up, you guys are amazing.
I confirmed that I am using MobileNet v1 0.25.
I rebuilt the library, deleted the old one and installed the new one in the IDE.
I realized that I had built the old library with float32 so I used int8 this time.
I still have the same problem as above: one inference then fail.
I have found a new symptom. When I closed and opened the serial monitor in the IDE without resetting the device I got a new error message:
Starting inferencing in 2 seconds…
failed to create snapshot_mem
My project ID is 47825 if you think there might be something there. I can also try swapping the Nano for another one if you think it might be a hardware issue, but I used this hardware to capture the data for this project successfully so I think it works.
In any case, I really appreciate the effort you are putting in to help me with this. Please let me know if I can provide any further information.
