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

Re: PROBLEM WITH FINGER PRINT SENSOR
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.

Re: PROBLEM WITH FINGER PRINT SENSOR
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.

Re: PROBLEM WITH FINGER PRINT SENSOR
Sir,
The sensor still doesn't work with SFG demo software. Have you found any solution for it.
Thanks

Re: PROBLEM WITH FINGER PRINT SENSOR
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

Re: PROBLEM WITH FINGER PRINT SENSOR
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.

Re: PROBLEM WITH FINGER PRINT SENSOR
We sell these for use with Arduino. Does it work with the Arduino example code?

Re: PROBLEM WITH FINGER PRINT SENSOR
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.

Re: PROBLEM WITH FINGER PRINT SENSOR
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:
