Function to send templates from your controller to the sensor about adafruit-fingerprint-sensor-library HOT 80 OPEN

Yes, but I had to touch the fingerprint sensor packet size to adapt it to the datapackets I was sending

from adafruit-fingerprint-sensor-library.

I want to download and store the template in my server datatabase, I am using NodeMCU and Php with mysql on server side. This function is not provided in the library. Can anybody please guide me on this?

from adafruit-fingerprint-sensor-library.

I was also in need of such functionalities (to read, save and write back template data to similar sensor models) and thus came up with an update to the existing library. @Dygear what you said is correct. I have a pull request pending about this. Please checkout my repository about this update. Also checkout the changes I've made.

However, keep in mind that writing template data from one model to another won't serve the purpose as different sensor models might use different template matching algorithms.

Hope I was able to help!

from adafruit-fingerprint-sensor-library.

I made the change and left everything as it is and it still doesn't work, it reads the template and uploads it without problems, but when reading the fingerprint it can't find it in the database.

It occurs to me perhaps to filter the data that is not necessary and save the template in a string, and when reading it see the percentage of coincidence, and if it is greater than 80%, for example, I would take it as good. I'm going to sleep for a while and when I wake up I'll do that test and let you know how it goes, thanks for answering :)

WORKS!!!!! Thank you very much, I have searched everywhere and your library was the best that worked for me, very simple and intuitive everything, really thank you very much, you are a genius, I enclose my code in case it helps someone

@dody3030 I left the store fucntion as it is in the original library. Seems more likely a sensor issue. Will check anyways and get back if any solution is found.

from adafruit-fingerprint-sensor-library.

@AsifKhan991 , I am using R503 capacitive fingerprint sensor and wanted to store fingerprint data from cloud to new sensor. Your update woks fine with minor modification. Thank you very much for that.

I tried to merge your get fingerprint and store fingerprint examples in one. I failed initially and got error in write_template_to_sensor() function, later I added Serial2.read() as long as Serial2.available() remains true(Serial2 is a port I am using for my sensor). After this it works fine. What I don't understand is it gave me 447 bytes extra. What are those ?? Do you have any Idea about this ??

OK so I was using 768 size but it turns out that template size is 1536 for R503 as well. I have changed the template size and it is working fine. Datasheet I was following was old so I have asked GROW directly they provided updated manual that I have attached below.

Try using larger buffer for the software serial
something like
SoftwareSerial mySerial(D7, D8, false, 1024);

default is 64bytes
packages of template are 128bytes+11bytes
maybe it got overwritten

I made this with the latest version of the code. I need to put templates back to the sensor when I free the memory. The documention of the sensor says it's allowed, but not implemented in the library. This does not work, it will be fine to improve the library.

i have written on there, how to send template fingerprint to module fingerprint

from adafruit-fingerprint-sensor-library.

I want to download and store the template in my server datatabase, I am using NodeMCU and Php with mysql on server side. This function is not provided in the library. Can anybody please guide me on this?

of course, i can help you. NodeMCU i think can use as Arduino, so it can be work with module fingerprint R307 or DY50

Hello adityadate1997,

You need to store the template into your fingerprint sensor and compare it with the fingerprint that the sensor is receiving from the user. Probably, you will need to store templates from a database to the database of the sensor to check the fingerprint that your sensor has received and compare it with the fingerprints of the database.

Good luck

from adafruit-fingerprint-sensor-library.

@rodrigotabsan Are you able to get the templates out from the sensor and store those templates into another sensor's flash memory? If so what sensor are you using ?
I'm also trying to achieve the same thing using NodeMCU and R307.

from adafruit-fingerprint-sensor-library.

@shreeramk1998 I didn't try that. I can't get the fingerprint template I have stored in an external database to match the one I put on the sensor. I'm not sure this can be done... I've been working on this for several months with no results.

please guide me
Thanks

I want to download and store the template in my server datatabase, I am using NodeMCU and Php with mysql on server side. This function is not provided in the library. Can anybody please guide me on this?

of course, i can help you. NodeMCU i think can use as Arduino, so it can be work with module fingerprint R307 or DY50

Can we connect through an email? I'll send in the required code for you to see.

I'd be really interested to find out how you did that. Could you please reach out to me or make what you learned public by any means?

from adafruit-fingerprint-sensor-library.

After reading all the datasheets I have found. Does someone knows if the template/signature of the fingerprint format follows some kind of standard such as ISO, ANSI,...?
Thanks in advance!

from adafruit-fingerprint-sensor-library.

So, I read the datasheet, looks like this uses the DownImage function documented here on page 19. You can also upload an image to the sensor with UpImage (found on page 18.)

The images themselves and the formatting used are documented on page 8 (under the title 4.1.1 Image Buffer) says that the captured images are 256x288 pixels in size.

When uploading or downloading images though the UART port, in order to speed up the speed, only the upper four bits of the pixel byte are used that is, 16-level grayscale is used, and each byte represents two pixels (the high four bits are one pixel, and the low four bits are the same. A pixel in the next adjacent column of the row, that is to pixels are combined into one byte and transmitted). Since the image is16 grayscale levels, uploaded to PC When displaying (corresponding to BMP format), the grayscale should be expanded (expanded to 256 grayscale, i.e. 8bit bitmap format.)
Transmission though the USB port is a full 8-bit pixel, that is, 256 gray levels.

What I think is needed is for the image to tz function Img2Tz page 19 again, after capturing / sending two images with that function it stores the first image in CharBuffer1 and CharBuffer2. Then you can run the RegModel function (page 20) that takes the contents of CharBuffer1 and CharBuffer1 and tries to make a template model out of it.

On page 21 it looks like you can straight up take the template model (they are now calling it characteristics) and "upload" that to the host computer. On page 21 again it has the DownChar function that allows you to download into the characestirics buffers and then you can save them into the flash memory with the store function call.

I think the only functions you really need are the UpChar, DownChar and Store functions in order to sync a database across multiple devices and have it return the same position ID. If they became out of sync you can always delete the database and copy one fingerprint reader to another using the Empty function (documented on page 24).

Edit: I call all of these functions, but really they are called "Instructions" in the document parlance.

and it throws me the error exponent has no digits

What can be? Thanks in advance :)

These are actually hex values. You need to put '0x' before the hex values. Like this: 0xFE

@Gitare420 check this repo again after 4hrs (busy with other stuffs) , I will update the get template example to show hex values with '0x'.
I know it's hard to put '0x' before 512 values.

from adafruit-fingerprint-sensor-library.

Thanks for answering, it was easy to put the 0x using the replace tool of the notepad, I stay like this

uint8_t fingerTemplate[512] = {0x3, 0x3, 0x59, 0x16, 0x0, 0x1, 0x20, 0x1, 0x7D, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x11, 0x0, 0x3, 0x0, 0x6D, 0x0, 0xC, 0x33, 0xCC, 0xFC, 0xCF, 0xFF, 0xFF, 0xFF, 0xBB, 0xEE, 0xFE, 0xEA, 0xEA, 0xAA, 0xA9, 0xA5, 0x56, 0x56, 0x55, 0x55, 0x45, 0x54, 0x45, 0x44, 0x44, 0x40, 0x4, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x49, 0xA, 0xD8, 0x7E, 0x28, 0x13, 0x93, 0x5E, 0x52, 0x20, 0xC7, 0x1E, 0x22, 0xA1, 0x90, 0x3E, 0x25, 0x2E, 0x28, 0x1E, 0x25, 0x37, 0x4E, 0xBE, 0x48, 0x39, 0x47, 0xBE, 0x4D, 0x17, 0xC4, 0x7F, 0x5A, 0x32, 0xDE, 0xFF, 0x33, 0x43, 0x48, 0x1F, 0x3E, 0xC3, 0x48, 0xDF, 0x37, 0xB4, 0x9, 0xFC, 0x3C, 0x2C, 0xD6, 0x7D, 0x3E, 0x18, 0xC2, 0xDA, 0x30, 0x20, 0x12, 0xFA, 0x37, 0xAF, 0x8F, 0xDA, 0x34, 0xB8, 0x9, 0x1A, 0x2E, 0xBA, 0x4C, 0xBA, 0x2A, 0xBE, 0xE, 0x3A, 0x30, 0xBF, 0x9, 0x9A, 0x43, 0x19, 0xD9, 0x58, 0x2B, 0xA1, 0x69, 0x78, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x3, 0x3, 0x55, 0x14, 0x0, 0x1, 0x20, 0x1, 0x7F, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0xF, 0x0, 0x1, 0x0, 0x6D, 0x0, 0xC, 0xC, 0x33, 0xCF, 0xCC, 0xFF, 0x3F, 0xEE, 0xFF, 0xEF, 0xEE, 0xEB, 0xAE, 0xBB, 0xA6, 0x99, 0x99, 0x95, 0x95, 0x56, 0x51, 0x55, 0x15, 0x11, 0x54, 0x41, 0x4, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0};

Then I used the write function and it uploaded without problems, but when using the fingerprint scheme to read it tells me

"Image taken
Image converted
Did not find a match"

Did I do something wrong?

from adafruit-fingerprint-sensor-library.

@Gitare420 Did you use the same sensor for reading the template from and writing to back it? What is the model pf the sensor? Also what id you enrolled against?

from adafruit-fingerprint-sensor-library.

use the same model 071405 finger to read and write, with the id 1

from adafruit-fingerprint-sensor-library.

I am attaching my codes, I am using the example ones that the library brings, sorry for my bad English, I am using google translator, greetings from Chile :)

@Gitare420 in the "write_to_sensor" example you have to comment out or delete the line "memset(fingerTemplate, 0xff, 512);" if you've manually put the template data in the array buffer before this line. (as you have done). This line was simply done to initiate the array buffer when it was previously empty. So comment out his line and let me know if it works or not.

I was also in need of such functionalities (to read, save and write back template data to similar sensor models) and thus came up with an update to the existing library. @Dygear what you said is correct. I have a pull request pending about this. Please checkout my repository about this update. Also checkout the changes I've made.

However, keep in mind that writing template data from one model to another won't serve the purpose as different sensor models might use different template matching algorithms.

Hope I was able to help!

yap, that's right

from adafruit-fingerprint-sensor-library.

@Gitare420 @hanifizzudinrahman I made some changes in the write_template_to_sensor() function. Check if it works now. Also currently I don't have access to the modules. Tomorrow I will have them and check again thoroughly.

from adafruit-fingerprint-sensor-library.

Hello, I updated the library and it's still the same, from what I've seen my model 071405 is the least used, it may be the reason why it doesn't work, these are the data that the fingerprint example gives me:

Reading sensor parameters
Status: 0x0
SysID: 0x0
Capacity: 300
Security level: 3
Device address: FFFFFFFF
Packet length: 128
Baud rate: 57600
Waiting for valid finger...
Sensor contains 1 templates

I think I'll buy the 307 model through AliExpress (it doesn't exist in Chile) and I'll keep trying there so as not to waste my time, I'll be attentive to the updates, thank you very much :)

from adafruit-fingerprint-sensor-library.

I leave the last test I did in case it helps someone :)

There were indeed some issues with template buffer size. Those are now fixed. @Gitare420 sorry to bother, but will you please let me know if the issue is now solved or not? (use the new "get_direct_template.ino" example to get the template)

Create an example to add fingerprints and get the templates at the same time. I use an esp32.

Sorry, I made an account here 4 days ago and I'm learning how this works :)

from adafruit-fingerprint-sensor-library.

Hello, sorry for so many doubts, this is the last one hahaha, how can I write the templates from an sd card? I use an esp32 and the libraries:

#include "FS.h"
#include "SD.h"
#include "SPI.h"

I have a txt that stores only 1 template:

0x3, 0x3, 0x5B, 0x16, 0x14, 0x1, 0x3C, 0x1, 0x84, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x12, 0x0, 0x4, 0x0, 0x85, 0x0, 0x3C, 0x0, 0xC0, 0x3C, 0xCC, 0xCF, 0xFF, 0xF3, 0xFE, 0xFF, 0xFF, 0xBE, 0xEB, 0xAA, 0xBA, 0xAA, 0xAA, 0xAA, 0xBA, 0xA9, 0x95, 0x65, 0x55, 0x55, 0x55, 0x55, 0x51, 0x15, 0x54, 0x0, 0x0, 0x0, 0x44, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x1, 0x57, 0x12, 0x5A, 0x5E, 0x1C, 0x99, 0x53, 0x5E, 0x56, 0x98, 0x4, 0x3E, 0x35, 0x1A, 0xD5, 0xBE, 0x67, 0x9A, 0x84, 0x3E, 0x26, 0x29, 0x53, 0xDE, 0x20, 0xAD, 0xD2, 0x1E, 0x33, 0x2E, 0x14, 0x7E, 0x76, 0xBE, 0x8, 0x1E, 0x51, 0xC0, 0xD9, 0xFE, 0x64, 0x23, 0xD9, 0xBF, 0x14, 0x26, 0xE9, 0x7F, 0x73, 0x38, 0x47, 0x7F, 0x47, 0xC0, 0x97, 0x3F, 0x27, 0xC2, 0x4E, 0x9F, 0x39, 0x3C, 0xD1, 0xFC, 0x3B, 0x3F, 0xC0, 0x98, 0x6C, 0xC4, 0xCA, 0xB8, 0x68, 0x40, 0x9C, 0xB9, 0x68, 0x43, 0x1E, 0x39, 0x68, 0xC5, 0x9E, 0x19, 0x7C, 0x21, 0x1A, 0x5E, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x3, 0x3, 0x57, 0x15, 0x0, 0x1, 0x20, 0x1, 0x85, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x5, 0x0, 0x4, 0x0, 0x7D, 0x0, 0x0, 0x0, 0x0, 0xC, 0x0, 0xCC, 0xC, 0xF3, 0xF3, 0xFF, 0xFF, 0xEF, 0xFF, 0xBF, 0xBE, 0xBA, 0xAA, 0xAA, 0xAA, 0xAA, 0xAA, 0xA9, 0x95, 0x55, 0x55, 0x55, 0x54, 0x55, 0x54, 0x11, 0x54, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0,

How can I write all that in the function

uint8_t fingerTemplate[512]={0x03,0x0E,....your template data.....};

As I understand
memset(fingerTemplate, 0xff, 512);
has something to do with it.

Thank you very much in advance :)

from adafruit-fingerprint-sensor-library.

Hello everybody, I'm confused about the template size, I got R503 fingerprint when I read the datasheet I noticed that the template size is 768 bytes not 512, is there is anything I need to change in AssifKhan991's libraries. Thanks in advance

from adafruit-fingerprint-sensor-library.

@dody3030 just change the array buffer size to 768. I.e : finger.get_template_buffer(768,your_arr_buff) to get the template data and finger.write_template_to_sensor(768, your_arr_buff) to write template back to sensor.

from adafruit-fingerprint-sensor-library.

write_template_to_sensor

@AsifKhan991 what about the memset(ref_buf, 0xff, 512) in Adafruit_Fingerprint.cpp

from adafruit-fingerprint-sensor-library.

write_template_to_sensor

@AsifKhan991 what about the memset(ref_buf, 0xff, 512) in Adafruit_Fingerprint.cpp

Updated this to take value from 'bufsize' variable

@dody3030 issues with your code:

1. You are using f_buf[512] when you mentioned your template size is 768 bytes. So replace all 512 to 768 in your code

2. Did not call the finger.loadModel(id) before calling finger.getModel(). Refer to "show_saved_template.ino" example.

Actually am trying to get the hex values during the enrollment, so do I need to loadModel() before I getModel?? I checked your previous code examples trying to understand in which stage exactly I have to get the hex, taking into account the template size is different, I will use your example get_direct_template. thank you for your replies really appreciated.

Usually the template remains on the char buffer if no other operation's done after enrollment. But it might be otherwise due to model variation. So yeah, safe to do so.

@AsifKhan991 from the example you have shared before, store_template_to_buf ,, I added only else statement to check if the function is executed successfully or not, I changed all 512 to 768 but not working.

There was another issue with the function. Fixed it, can you check?

@AsifKhan991 now I will try your example write_to_sensor and I will change the buffer size or all 512 to 768, you really saved my day .. you are really helpful genius guy thanks again and again. i was trying with the code for long time ago , eventually I start reading the datasheet, and I found that most of the capacitive fingerprint template size 768.

You are supposed to comment the line memset(fingerTemplate,0xff,768). Also use a valid Id to store the print (1-127)

from adafruit-fingerprint-sensor-library.

@AsifKhan991
1- I added two users.
2- I got the hex for the id 2.
2- I ran the example that delete all users. now the sensor db is clear.
3- I added the admin id =1 , now only one user is registered.
4- I opened write_to_sensor example and I commented out the memset line, and I added the hex to the variable uint8_t fingerTemplate[768] = {0x2,0x0,0xDD,0x2
5- Compiled, run
6- Added 2 as id for the required id. but got Storing error. I don't know why.

@AsifKhan991 Writing to the sensor work... I just added a delay for 10 seconds after writing the template and before storing to the sensor. everything is working fine now. your library is fine don't waste your time to check it. my sensor is R503 capacitive fingerprint and I think there is slowness while writing to the sensor. thanks for your code.

from adafruit-fingerprint-sensor-library.

@AsifKhan991 . I changed the text file content to store the template id and '%' as separator between the template id and template data I collect from fingerprint Sensor (1). The following is an example of the text file content stored in SD.

As you can see the file contain three different IDs and percentage sign as separator in addition to the template data. the problem is that am able to collect the data successfully but not able to send it to the write_template_data_to_sensor function, that accept two parameters one is int and the other is uint8_t.

Not a good idea to use seperator. What if the template contains a hex value that refers to the seperator in char?

from adafruit-fingerprint-sensor-library.

@AsifKhan991

Not a good idea to use seperator. What if the template contains a hex value that refers to the seperator in char?

but the template stored in non-hex , and the data passed to buf array is filtered by readBytesUntil from the position after the '%' sign till '#' sign, so it will be the same data that is collected from the sensor before. and I didn't change it to hex, because what I understand from your example the same data can be passed to uint8_t without changing to hex to be written back to different sensor of the same type.

from adafruit-fingerprint-sensor-library.

I see that your template data contains only decimal numbers. If you stored in decimal format and read directly as hex using readBytesUntil() then it's not gonna work. This is no issue with the library, mere the use of wrong data type. Please have a thorough look at the Arduino data types.

from adafruit-fingerprint-sensor-library.

  int read_len = myFile.readBytesUntil('#', buf, max_len);

Here's the issue, you are reading from the beginning of line. Also I see that you template contains decimal numbers. Did you write template to the file as integers? If yes, then please thoroughly go through Arduino data types documentation to see how yo reconvert them. This is not an issue with the library, mere wrong data types and indexing.

before that line there are two lines to get the template id

t_pkt = myFile.readStringUntil('%');
t_pid = t_pkt.toInt();

the first line put the next reading after the % sign int read_len = myFile.readBytesUntil('#', buf, max_len); and when I print the buf it showing exactly the data is collected for that template. but the issue is how to pass that buf to uint8_t as argument for the write_template_to_sensor function. the following is an example of buf output for each line.

2110618139205590132229162293621661562201332819724586572............ till the end of the output. I verified this and I found it is same as the data collected from the sensor for template 1

from adafruit-fingerprint-sensor-library.

Please read my most recent comment. Anyways there's an easy solution, just create seperate files for seperate templates and name the file with id number. Then just read the directory and save by the name.
Write the template data as byte/hex on the file.

Hello, were you able to solve your problem? i'm stuck on the same

me too, waiting Asifkhan to reply, beside I have encountered one more issue, I have to add the first ID "Admin" or ID 1 using Adafruit example, I can not upload the first template to the sensor directly using Asifkhan code, beside at least one finger of five templates is not recognized by the sensor. I don't know why, I checked the template length, the library, but still stuck.

from adafruit-fingerprint-sensor-library.

Please read my most recent comment. Anyways there's an easy solution, just create seperate files for seperate templates and name the file with id number. Then just read the directory and save by the name. Write the template data as byte/hex on the file.

@AsifKhan991 I changed the function to load the template from the file that contain only hex stored from the sensor for only one template.

void loeadTempFromFile(){
  File myFile;
  myFile = SD.open("fprint.fdb");
  uint8_t t_buf[768] = {};
  int t_data = myFile.readBytesUntil('\n', t_buf, sizeof(t_buf));
  for (int i = 0; i < 768; i++){
     Serial.print(t_buf[i]);
  }
  myFile.close();
}

From what it looks like you are facing data type or file format issue. Please share the code you used to write to the file. Also, how about using ".txt" as the file format?

from adafruit-fingerprint-sensor-library.

Hi, has anyone found a solution? The truth is I don't have much to contribute, I've tried everything and I can't load the fingerprints from the txt file to the fingerprint reader, what most complicates me is adding the 0x to the templates, I don't understand very well what they do or how to put it before prefix in the uint8_t. Thank you very much in advance. @dody3030 @AsifKhan991

Good evening everyone, did anyone manage to solve the problem?
I have the 502-f and I have tried several ways but I can not write the template in the FP, I have changed the buffer size to 768, I put a delay as the companion said and nothing, the error Storing Error still appears. @AsifKhan991 plss help us

from adafruit-fingerprint-sensor-library.

Are u getting error msg in serial console? If yes share the error msg please.

from adafruit-fingerprint-sensor-library.

Hi, thanks for your answer, I explain: when I try to send a template using your library I get error storing, doing debug I managed to see that the FP sends a code 18H that corresponds to error to save in flash. Looking at the datasheet of the R502-F I noticed that the template must have 1536 bytes of data, so I modified the buffer and still with your library gives me error.

With the help of Grow support people I did a test directly using a serial debug software, I finally got the sensor to save the template. Here is the file they sent me and it helped me.

R建议将503上传的模板文件不做拆包合并处理,直接进行存储,发送的时候直接按循序发送即可,大部分人是在这一步出错.
It is suggested that the 503 uploaded template files should be stored directly instead of unpacking and merging. When you send it, just send it in order. Most people make mistakes in this step.

@AsifKhan991 I still can't send template using your library, I think it has to do with the buffer size, it seems that being so big it generates some kind of error and the data is not sent complete.

from adafruit-fingerprint-sensor-library.

Could be. Or may be the Hex commands are different for your module. Cross check your sensor's datasheet with standard adafruit one.

from adafruit-fingerprint-sensor-library.

@AsifKhan991 uses exactly the same commands, the error occurred because for some reason this module does not accept a template with all the values in FF.

in conclusion to use your library with the R502-F you just have to change the buffer and send real templates, not use the memcpy.

Thanks for your help

from adafruit-fingerprint-sensor-library.

@AsifKhan991 , I am using R503 capacitive fingerprint sensor and wanted to store fingerprint data from cloud to new sensor. Your update woks fine with minor modification. Thank you very much for that.

I tried to merge your get fingerprint and store fingerprint examples in one. I failed initially and got error in write_template_to_sensor() function, later I added Serial2.read() as long as Serial2.available() remains true(Serial2 is a port I am using for my sensor). After this it works fine. What I don't understand is it gave me 447 bytes extra. What are those ?? Do you have any Idea about this ??

from adafruit-fingerprint-sensor-library.

@DharmikEC Hey! That's awesome thanks for attaching the sheet as well!

from adafruit-fingerprint-sensor-library.

@AsifKhan991 WORKING.!!!!, Thank you too much, I ready don't know how to thank you,, Im sorry it's working, I forgot to copy the updated ccp. thanks alot
