Hi!
I am trying to connect my finger print scanner with arduino using logic level converter. My sensor is working fine with SDK_DEMO.exe software when I connect with my PC port. But not working with arduino. I am only receivng this:
FPS - Open
FPS - SEND: "55 AA 01 00 00 00 00 00 01 00 01 01"
#include "FPS_GT511C3.h"
#include "SoftwareSerial.h"
FPS_GT511C3 fps(4, 5);
void setup()
{
Serial.begin(9600); //set up Arduino's hardware serial UART
fps.UseSerialDebug = true; // so you can see the messages in the serial debug screen
fps.Open(); //send serial command to initialize fps
}
void loop()
{
// FPS Blink LED Test
fps.SetLED(true); // turn on the LED inside the fps
delay(1000);
fps.SetLED(false);// turn off the LED inside the fps
delay(1000);
}

I am following this example:
Just to clarify last 2 lines:
I connected PIN4 to HV and then connect from HV to 5V pin of arduino.
I connected directly LV of converter to 3.3V pin of arduino
