Hi,

Is it possible to store finger image locally to upload it to the cloud server?

Hi Chris,
I have some strange problem, seems that whenever i try to enroll the finger i get error that fingers do not match.
I use example from Bastian from file example_enroll.py as you suggest with no luck.
All test of sensor are passing and I use R503 sensor on ESP32.
Also if I skip condition compareCharacteristics then enrollment succeeds and when i try to search he found the template but i get error on downloading characteristics downloadCharacteristics(FINGERPRINT_CHARBUFFER1).
Do you have any idea what can be wrong, thanks in advance?

I ran the pyfingerprint.py code on my esp8266 and recieved this error below. Please how do i get to solve this problem.

MemoryError:

Hello when i'm using zip file from git to add this package into my esp32 program then its showing error.
N.B: I'm new to thonny ide.

I want to want to develop a fingerprint attandence project that could store fingerprint data on mysql. When a student register his/her fingerprint, the fingerprint should be stored on mysql database.
