Waiting for valid finger to enroll - finger not detected

[alve89]

Hi @brianrho,

I just wanted to try your library to test my new FMP10 sensor with an Arduino Nano. Connection and the detection of the sensor module itself is working properly (pin 2+3).

ENROLL test
Found fingerprint sensor!
Capacity: 150
Packet length: 128
Handshake command is supported.
Send any character to enroll a finger...
Searching for a free slot to store the template...

From here I only receive dots, nothing else. So it seems to me my finger is not being detected. Can you support me with that?

Thank you and best regards!

Weirdly it's working now, when I remove the finger and put it onto the sensor again.... sorry!
