SFG Demo is not working. how should it be fix?

Post by Maxwell223 »

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?
