Hello
Sounds like I am having the same problem.

In the arduino IDE, have loaded up the sketch that is posted on the site. I am using a UNO board.

Have re-soldered the thin wires from the reader to the thicker wires. When I power on I get one red flash. It does not flash again. When I try to open device in SFG Demo, I select my com port. this port has been confirmed in both the ardiuno IDE and tghe windows device manager.

The error I get is:

Have been able to get the fingerprint scanner to work. Not with the windows program, that still will not connect with the error in the last post.

The change to get it to work with the scripts is this:

Each of the scripts are using SoftwareSerial and are configured to use ports 2 and 3:
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino (WHITE wire)
SoftwareSerial mySerial(2, 3);

so, attaching the green to port 2, and the white to port 3, it connects. I am able to enrole, delete, and validate using the scripts provided.

I will try to see if I can get the windows program to work, but I can continue my project with the sketch programs.

Thank-you

Strange that it works with the sketch, but not with SFG Demo. Most people have the opposite problem. Make sure that the baud-rate is correct. It should be 56700.
