Capacitative Fingerprint on Arduino not working

Products & Technology Grove
#1

Followed the wiki manual to get this device hooked up with your example code to an Arduino UNO. It receives continuous fingerprints (always the same). Can’t get it to work at all. Please assist.
Continuous stream on serial (without any finger on the sensor):
17:03:32.645 -> EF.1.FF.FF.FF.FF.1.0.8.32.0.FF.FF.0.7.2.40.
17:03:32.645 -> Uart===> : EF.1.FF.FF.FF.FF.1.0.8.32.0.FF.FF.0.7.2.40.
17:03:32.645 ->
17:03:32.645 ->
17:03:32.645 -> Please put your finger on the touchpad.
17:03:32.645 -> To verify your finger print.
17:03:32.645 ->
17:03:32.645 ->
17:03:32.645 ->
17:03:32.645 -> Uart<=== : EF.1.FF.FF.FF.FF.7.0.8.0.0.0.0.0.0.0.F.
17:03:32.679 ->
17:03:32.679 -> Verify ok!
17:03:32.679 -> Your finger temp id = 0

Can you provide a video? Let’s confirm if there are any defective products. @Gert_Nelen

I have the same issue. I got the sensor yesterday

Same issues here. Had problem to even compile original library, but after solving that, everything is just verified ok …
