R558 Fingerprint not picked

• Arduino IDE version (found in Arduino -> About Arduino menu): 2.3.2

Fingerprint sensor is not picked

AoA, it will not work look into data sheet of R558 quite a range of instruction codes are different you can make a new copy of adafruit liberary file and make changes there in both CPP and H, because no specific R558 liberay is available yet.
Also wiring of R558 is very ugly and not sequenced well. I found that Black is TX, Yellow is RX, Red is GND, White is VCC_3V3, Green is VCC_WAKEUP and Blue is TOUCH_OUT.

[faizannazir]

It works with adfruit library without modification

white, pin1-VCC
blue, pin2- TOUCH, we didn't connect it
green,pin3-VCC, we connect it with white cable.
yellow,black, pin 4,5, tx rx.
red, pin6 GND.

what about its aura led did worked as well?

No

[zshlomi]

thank for this thread - pin layout seems to work.
however, I could not enroll a fingerprint , failed to store with error 53 , any idea?
tried all the examples and AI help

[Gior80]

hi, got exact same response from sensor, when registering template the sensor return error 53 ! can some example be made?

[Gior80]

Working on it I found error, standing at r558s manual, is 0x35 = illegal data.
command are same between 503 and 558s. has anybody figured out ?

[carloswbarros]

The only thing that it doesn't seem to work is the storeModel, it's returning 53 (0x35, Illegal Data)
Did someone found a solution?

R558 & R557 requires minimum 4 times enroll so adjust your enroll part like just copy and rename this part 2 more times or you can do with for loop as well simple way to understand...
p = finger.image2Tz(3);
switch (p) {
case FINGERPRINT_OK:
Serial.println("Image converted");
break;
case FINGERPRINT_IMAGEMESS:
Serial.println("Image too messy");
return p;
case FINGERPRINT_PACKETRECIEVEERR:
Serial.println("Communication error");
return p;
case FINGERPRINT_FEATUREFAIL:
Serial.println("Could not find fingerprint features");
return p;
case FINGERPRINT_INVALIDIMAGE:
Serial.println("Could not find fingerprint features");
return p;
default:
Serial.println("Unknown error");
return p;
}

Serial.println("Remove finger");
delay(2000);
p = 0;
while (p != FINGERPRINT_NOFINGER) {
p = finger.getImage();
}
Serial.print("ID "); Serial.println(id);
p = -1;
Serial.println("Place same finger again");
while (p != FINGERPRINT_OK) {
p = finger.getImage();
switch (p) {
case FINGERPRINT_OK:
Serial.println("Image taken");
break;
case FINGERPRINT_NOFINGER:
Serial.print(".");
break;
case FINGERPRINT_PACKETRECIEVEERR:
Serial.println("Communication error");
break;
case FINGERPRINT_IMAGEFAIL:
Serial.println("Imaging error");
break;
default:
Serial.println("Unknown error");
break;
}
}

p = finger.image2Tz(4);
switch (p) {
case FINGERPRINT_OK:
Serial.println("Image converted");
break;
case FINGERPRINT_IMAGEMESS:
Serial.println("Image too messy");
return p;
case FINGERPRINT_PACKETRECIEVEERR:
Serial.println("Communication error");
return p;
case FINGERPRINT_FEATUREFAIL:
Serial.println("Could not find fingerprint features");
return p;
case FINGERPRINT_INVALIDIMAGE:
Serial.println("Could not find fingerprint features");
return p;
default:
Serial.println("Unknown error");
return p;
}

Serial.println("Remove finger");
delay(2000);
p = 0;
while (p != FINGERPRINT_NOFINGER) {
p = finger.getImage();
}
Serial.print("ID "); Serial.println(id);
p = -1;
Serial.println("Place same finger again");
while (p != FINGERPRINT_OK) {
p = finger.getImage();
switch (p) {
case FINGERPRINT_OK:
Serial.println("Image taken");
break;
case FINGERPRINT_NOFINGER:
Serial.print(".");
break;
case FINGERPRINT_PACKETRECIEVEERR:
Serial.println("Communication error");
break;
case FINGERPRINT_IMAGEFAIL:
Serial.println("Imaging error");
break;
default:
Serial.println("Unknown error");
break;
}
}
where you already have p = finger.image2Tz(1); and p = finger.image2Tz(2);

[Irfanislam]

Using for loop will make your code robust, shoter and decrease size as well because repeating "p = finger.image2Tz(uint16_t location);" 4 time is not professional.

I can't believe that worked! It was exactly that!
Thank you so much!

[zshlomi]

thanks for the info, looped 4 times and it works
success !!!!

Hope you got the solution as mentioned here.

Hi guys, I got a R558 fingeprint sensor some days ago and only now I found this thread.

I couldn't find the pinout and I used the one for R557 thinking that was similar but probably it is not.

Now I used the pinout specified here but nothing happens.
Maybe I burned the sensor :( could be?

I cannot see the led turning on and, moreover, I cannot receive any data from the sensor.

I connect the sensor to a PC via an FT232RL usb converter, using 3.3V.
Can you tell me what you think about this?
Ohh, another question. Do you have the datasheet for R558? I found the R558-S and I don't know if it works anyway.

Thanks a lot

[Irfanislam]

I found that Black is TX, Yellow is RX, Red is GND, White is VCC_3V3, Green is VCC_WAKEUP and Blue is TOUCH_OUT. If still its not working after above changes in adafruit enroll code maybe yiu R558 has malfunctioned due to wrong wiring as case you have connected it to PC where current is higher, not sure, I have done the same but still after my R558 was fine. You can search and find R557 data sheet its same R558 is not avaliable I think.
