I rewrite the file Adafruit_Fingerprint.h

I have a problem showing loadchar and enroll upchar in sketch ..
What exactly did you change and what problems did it cause?

Have you tried the code posted earlier in this thread?

BANNED, thank you for posting the library file! You say you rewrote the arduino_fingerprint code to call the function of the library. What exactly did you change in the code to get it working? And do I have to change something inside Adafruit_Fingerprint.h file as well? The problem is when I only replace the Adafruit_Fingerprint.cpp file with yours I get this error from arduino when calling loadChar(): 'class Adafruit_Fingerprint' has no member named 'loadChar'. Thank you in advance!

Thank you @BANNED for sharing the code, it is very useful.

Below are the 2 sets of output characteristic value (that i used @BANNED) that i obtain when i enroll and matching my fingerprint with ID=4

Please, can anyone tell me what is the code about so that it is easy for to write my own matching algorithm on the central server
