Hello everybody,

i have a problem with my fingerprint sensor:

" Power Adapter-5V 4A WIKI - DFRobot "

I've read lots of things, and I did not find the solution!

my sensor fingerprint is properly connected to the arduino uno, and it works, recognize the finger in the "enroll" and the "fingerprint", the problem is when I want to save several fingers. If i want to save 3 fingers, (ID1, ID2, ID3) it only saves me the last, and as ID0. The "fingerprint" only works with the last finger that I keep.

Attached is the ID1 image in the monitor series

Does anyone know how to solve this problem? I'm working with IDE 1.6.5 and have tried almost every other one and it does not work either.

but only know that both these modules have same frequency band and data rate.

It's OBVIOUSLY your code that is wrong. It's equally obvious that you didn't bother posting it.

Do NOT post pictures of text ever again.
