Sfg demo for r307 fingerprint module8/4/2023 it is always "Open Device Fail! Please check the password and device address!". 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.īut the SFG Demo is NOT working.i wonder what should i do to work it. SFG demo error: open device failed, please check the passwor Post by dkanday » Tue 1:43 pm Hi There, I am using Audrino Uno and have tried connecting R305 and AS608 fingerprint sensor. The Manual is targeted for hardware & software developing engineer, covering hardware interface, system resource, instruction system, installment information, etc. How is this even remotely an Arduino problem You have some application whose only relationship to Arduino is that it is remotely possible that there is an Arduino on the other end of the serial port that it is trying to talk to. again my com is COM8 and i even try my other arduino and usb port(COM 6) also error. Thank you for you selection of R30x series Fingerprint Identification Module (Module) of SFG. now this is where the problem comes in-there is an error that i should check the device address. but it is starting to get lag for 2-3seconds then a pop up "Open Device Fail! please check the password and device address!". 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. Scenario: According to a Udemy Lesson, i can use SFG Demo and use Arduino Uno to enroll a fingerprint with R307.
