I kind of ruined the module from being returned because I've glued it in place. still I woulI would like to see if there are an options. I have the library loaded up and running
connected @ 9600
using digital pins 2 and 3 (also in reverse)
when i powers up the red led flashes once then stops.
While connected to the SFG demo It gets a connection error or wrong password error attempted changing from COM port 9 to COM port 2
while loading the enroll example from the added library
any suggestion? would I be able to get a full or partial refund with the residue now on it?

Re: Fingerpritn reader
Are the wires coming from the reader (the green ones) stranded or solid? If they are solid just plug them directly into the Arduino without using the breadboard. If they are stranded solder on a piece of solid 22 ga wire.

Re: Fingerprint reader
the green wires where strained. I replaced them with cat 6 solid strand wire getting same error.
any other ideas?- adafruit_support_rick

Does the error come back instantly, or does it take 3-4 seconds to appear?slydoug12 wrote:While connected to the SFG demo It gets a connection error or wrong password error attempted changing from COM port 9 to COM port 2

Re: Fingerprint reader
error takes a few seconds.. right after selecting the COM port that the uno is using

Re: Fingerprint reader
That is a communication error between the Arduino and the fingerprint sensor. If it came back right away, it would have been a bug in SFGDemo. So you probably have a bad connection on the data lines.
Cat6 wire is probably too light to make a good connection inside the Arduino's pin headers. You should use 22AWG wire.

Re: Fingerprint reader
So I did one better. I hope I haven't ruined any ability to return the module.
Soldering thicker gauge wire to crappy connecting wires didn't make any sense to me. So I soldered solid strand jumpers directly to the board.
it powers ups( verified via the red flash) getting the same issue.
wire order from right to left looking at picture as is: black, white, green, red. anything else 4 me to try?

Re: Fingerprint reader
Let's replace it. But next time, just solder some 22awg to the ends of the wires.
Please email [email protected] with a link to this thread for a replacement fingerprint sensor

Re: Fingerprint reader
Ok so new fingerprint reader has arrived and I bought some 22gauge solid stand wire.
and did as you asked.
What did I screw up now!?

Re: Fingerprint reader
Does it work with SFGDemo? What symptoms are you seeing?

Re: Fingerprint reader
You are running SFGDemo with the reader attached to Digital 0 and 1, and the blank sketch running on the Arduino? Have you tried reversing the green and white wires in D0 and D1?

Re: Fingerprint reader
no i was not running blank program I did have the wiring correct.
OK!!!!! progress it connects but gives no hardware info attempted to set buadrate, package size, and secure level but selecting any of the 3 i get .....
(yes program is ran as admin) ...... why!!!
its like this thing is BANNED me!
what else you got?

Re: Fingerprint reader
I don't think you want to mess with those. Can you enroll a finger? See an image?slydoug12 wrote:attempted to set buadrate, package size, and secure level

Re: Fingerprint reader
no... I cant when selected it does nothing..
the reader doesn't light up nor does it scan a finger
