Using this:
https://www.adafruit.com/product/4750

Intentionally placing wrong finger on second scan but not getting mismatch error.

** EDIT ** adding Serial Monitor output from running enroll sketch and intentionally using two different fingers:

I second this, using this fingerprint sensor:
https://www.adafruit.com/product/4651

When purposely using different fingers during enrolling, a mismatched error is expected but it does not occur.

I also have this problem.

I can reliably recreate this behavior with PID 4750 mentioned in initial post above.

But it's working OK testing with PID 4651.

Here's with the same finger, just to prove it does match as expected:

And here's with using different fingers. Tried four times but it never saw them as same.

Issue #120 is a repeat for PID 4651 behavior.

Is there any progress on this? :)
I'm in the same boat than the initial author...
