The sensor supports the FPM_NOFINGER (0x02) code but if finger.getImage() is called after finger.image2Tz the function finger.searchDatabase does not find the finger. Result from sensor: EF 01 FF FF FF FF 07 00 07 09 01 EE 00 00 01 06

Without finger.getImage() after finger.image2Tz: EF 01 FF FF FF FF 07 00 07 00 00 01 00 60 00 6F ( Found ID1 with confidence of 96 )

Interesting, haven't seen this before and from the datasheet, there's no explanation for why its happening. Can you send the serial output for both cases, starting from the startup message that shows the capacity? Also turn on debug to print everything.

Of course, I can do it next week

Huh, I imagine its because of some difference in their firmware, it would seem the template buffers are getting wiped/overwritten after each image scan. I'll merge your changes but instead move that code block after the search is complete, so the option to wait till removal is still there.

Can you share wiring ??

brianrho commented 4 years ago

Just search Google images.

No led on in r503 sir
