I purchased a Finger Print Scanner (FPM10A) from AliExpress.
FPM10A Fingerprint Reader
Unfortunately I am not able to use it.
It has 6 pin connector with no datasheet, so I searched Google and found the connection diagram.
I cut this cable and connected the header so that I can use it with Arduino Mega Board.
But when I connect this sensor with Arduino, I did't see the Red Led blinking, not even for a single time.
I thought it will blink, whenever supply is connected, from the link given above, it is mentioned that it can also work on 5V, even i provided 5V supply (External Supply also).
I also cross-checked my connections, with a multi-meter and marking on the bottom of this PCB and it looks everything is connected properly.
There are some test pads like T(tx), R(rx), 3v3(VCC) and GND, and i checked with multimeter, everything looks fine to me.
I tried to run the enroll example present inside Adafruit Fingerprint scanner library but nothing works.
There is a Windows PC application used with this sensor, SFGDemov2.0, even with this application I am not able to connect.
I received the following error.
I used a serial sniffer tool and found that PC application is sending data, but this module is not responding at all.
Can anyone please confirm, If I received a faulty module or still there is any hope to get it working.
The reason I am saying that this sensor is faulty is because, I assume, that whenever someone supply power to this sensor, the red led will start blinking and I haven't seen this.
Those who have used this module can suggest me.
