Adafruit Fingerprint Scanner not taking enroll image

Post by ojhar »

Hi,

I am running into an issue with the Adafruit Fingerprint sensor. It is correctly wired to an Arduino Uno (it is lighting up and is being detected just fine). This is the serial output.

Code: Select all

Found fingerprint sensor!
Reading sensor parameters
Status: 0x0
Sys ID: 0x0
Capacity: 240
Security level: 3
Device address: FFFFFFFF
Packet len: 128
Baud rate: 57600
Ready to enroll a fingerprint!
Please type in the ID # (from 1 to 127) you want to save this finger as...
After entering 1 at this point:

Code: Select all

Enrolling ID #1
Waiting for valid finger to enroll as #
.
.
.
.., and the dots continue indefinitely, the sensor never recognizes my finger placed on it. It never takes the image.

I am using the enroll code on the Adafruit Fingerprint Sensor Library v2.1.0 on Arduino IDE 2.0.1. How can I fix this issue?

- Thanks

Check your wiring and the continuities of the jumper wires. If there is no fault found in any of them, maybe the sensor itself is faulty.
