Devices im using:
Arduino Uno R3 (x2)
R307 Fingerprint Module
Software im using:
Arduino IDE
SFG Demo V2.0
(Pin Connections:
Arduino - R307 Fingerprint
5V - 5V
GND - GND
TX(pin1) - TXD
RX(pin0) - RXD
scenario: According to a Udemy Lesson, i can use SFG Demo and use Arduino Uno to enroll a fingerprint with R307. in the first tutorial, i should first upload a Blank Sketch, then open SFG Demo software, then click Open Device and find the correct COM....which in my case is COM8. but it is starting to get lag for 2-3seconds then a pop up "Open Device Fail! please check the password and device address!". now this is where the problem comes in---there is an error that i should check the device address. again my com is COM8 and i even try my other arduino and usb port(COM 6) also error. now after that i also tried a simple "enroll" sample code from Adafruit Github Fingerprint Library, i uploaded it to my both Arduino Uno, and it works, i can enroll and match.
but the SFG Demo is NOT working...i wonder what should i do to work it. it is always "Open Device Fail! Please check the password and device address!". anyone can help me to solve this?
SFG Demo is not working. how should it be fix?
