i need a source code pf system fingerprint pls help me😊
hey i enroll the fingerprints but when i run the code for checking the confidence level then it shows very low confidence level like 2,10,3 . what should i do?
Great job is very helpful I want to know if we can download the finger template from the fingerprint sensor to store him in the computer and aslo send the template from the computer to the sensor

Hey, thanks! Unfortunately no it is not possible from the API. One idea you can use is to use the ID generated by the fingerprint during enrollment and save or map that number to a particular record like a database. Please subscribe to my channel if you have not done so. Thanks!

Hey, not sure what you mean by that. But I have done several web projects that uses fingerprint. I got hired to develop those projects.

@@DonskyTech I ask if you can set up a platform whose access is secured by fingerprint like a banking platform
it is showing random text in my case. Please solve
i only see a blank serial monitor for my case when i upload the code, can someone help me please. i have selected the correct baud and connected the sensor very well

Hey, are you using Arduino IDE or PlatformIO?
Is it still possible to use the fingerprint sensor if I used the GPIO 18 and 19 for the RX and TX connection? if so, how do I go about in doing that? Thansk for the help!

Unfortunately, there is nothing in the API of the library to do this. I had the same issue and I was looking for a way also but have not found any workaround.
bro i got an unknown error in checking
My fingerprint only blinked once and shut off. No fingerprint sensor detected on serial monitor. How to fix??

Hey, that is tricky but I would check the wiring first as that could be the problem. Please consider subscribing to my channel to be notified for more content. Thanks!

@@junkoscarlet6586 Well if you have an extra ESP32 then you could swap it out to check. Usually its a wiring issue unless either your ESP32 or your fingerprint sensor is toasted

@@junkoscarlet6586 hey, quite hard to figure out the problem without seeing it. If you have an extra Fingerprint sensor then try it with that one. Your sensor might have some issue as well.
