Re: PROBLEM WITH FINGER PRINT SENSOR

Post by niks912 »

Sir,
I received my replaced sensors but i regret to inform you that even the new ones are behaving the same way as the older sensors. It can search only the last enrolled finger and that too returns an id 0 irrespective of id assigned to it.

I tried with a different arduino and also a fresh copy of software and library but it fails to work.

Kindly give an appropriate solution.

Thanks

We have tested some of these in-house and have reproduced the problem. It appears that there has been a design change that affects our most recent shipment. We are checking with the manufacturer to find a solution.

You can set up a second SoftwareSerial port for the other one. Just be aware that you can only listen on one port at a time. You have to call the "Listen()" command to switch between them. http://arduino.cc/en/Reference/SoftwareSerialListen

The other option is to use a Mega which has multiple hardware serial ports.

Sir,
The sensor still doesn't work with SFG demo software. Have you found any solution for it.

Thanks

The SFG Demo software is buggy. I can't get my own copy to work. It works on some machines and not on others. I've tried a lot of things, but I never found a way to make it work

So what is the solution now.
I bought this product paying a lot more than local available product and now it doesn't serve the purpose.

We sell these for use with Arduino. Does it work with the Arduino example code?

Depends on machine. It works on some machine and doesn't on others.
And in your product description page you have clearly mentioned the windows software where it works.
Expecting a better solution from you.

Thanks

Well, I just tried something I never tried before, and it actually works with SFGDemo. I tried connecting the fingerprint sensor through one of these:

You can buy one of those cables.

Or, if you're not satisfied with this solution, please email [email protected] for a refund.
