Function to send templates from your controller to the sensor #36

ricarduscat · 2017-12-16T17:08:42Z

uint8_t Adafruit_Fingerprint::downloadModel(uint16_t id, uint8_t packet_1[], uint8_t packet_2[], uint8_t slot) {
  uint8_t packet[] = {FINGERPRINT_DOWNLOAD, slot};
  writePacket(theAddress, FINGERPRINT_COMMANDPACKET, sizeof(packet)+2, packet);
  uint8_t len = getReply(recvPacket);
  
  if ((len != 1) && (recvPacket[0] != FINGERPRINT_ACKPACKET))
   return -1;
  if (recvPacket[1] == 0x00) {
    writePacket(theAddress, FINGERPRINT_DATAPACKET, 130, packet_1);
    writePacket(theAddress, FINGERPRINT_DATAPACKET, 130, packet_2);
    return recvPacket[1];
  } else {
    return recvPacket[1];
  }
}

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.

The text was updated successfully, but these errors were encountered:

This function worked for you? Did you find another solution?

ricarduscat · 2018-03-26T14:44:59Z

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

marianodato · 2018-03-26T18:20:24Z

@ricarduscat could you explain how to do that?

milindrc · 2018-09-27T05:12:23Z

@ricarduscat please explain the parameter you need to pass to this function.

sand007man · 2018-09-28T09:37:07Z

i am able to enroll ,search fingerprint but when i load show_fingperprint _template it is showing some "??" values in the serial monitor . even small help will be greatly appreciated . I am using this fingerprint with node_mcu esp 12e...i feel its something related to memory buffer !!

hanifizzudinrahman · 2019-02-21T04:54:48Z

recvPacket

what is "recvPacket"? the last packet, or what?

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

@ricarduscat If possible can you please expand on this code ?(What are the parameters..etc). Is there any other way where I can load the templates from one sensor to other sensor. BTW I am using R307.

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

adityadate1997 · 2020-03-13T10:49:52Z

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?

yes, you can see my profile to get my new phone number or email

adityadate1997 · 2020-03-18T05:14:36Z

Sir, we have downloaded the fingerprint template data from the module r305 using the show_finger_template library. It gives us an array of size 512....we want to compare this stored array on server side. What exactly do we need to do? We tried comparing the array byte by byte but it does not give proper output. Can you guide us on how to match these templates sir. Thank you.

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

shreeramkulkarni · 2020-06-11T16:11:29Z

@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.

rodrigotabsan · 2020-07-01T08:40:53Z

@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.

Hello
This is the 3-finger pattern output stored in the module
I have saved these templates in the server database. Can I restore these templates to another module (fingerprint) and be usable?

Do it with example code "Upload", so the template will move to another module fingerprint

mlinaje · 2021-09-29T11:38:41Z

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!

Dygear · 2022-06-20T01:33:45Z

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.

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!

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.

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

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?

AsifKhan991 · 2022-09-06T11:53:34Z

@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?

Gitare420 · 2022-09-06T12:00:31Z

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

@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.

@AsifKhan991 returns Storing error. I changed all 512 to 768.

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

dody3030 · 2022-09-14T11:28:23Z

@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.

Output:
Found fingerprint sensor!

@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.

dody3030 · 2022-09-14T16:46:04Z

@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.

dody3030 · 2022-09-25T07:29:08Z

@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. Thanks in advance.

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

@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.

AsifKhan991 · 2022-09-25T09:03:23Z

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.

dody3030 · 2022-09-25T09:05:13Z

  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.

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();
}

Output from file after loading to uint8_t:

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 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?

Gitare420 · 2022-10-17T06:40:45Z

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

AsifKhan991 · 2023-02-10T17:46:41Z

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

cheotrix · 2023-02-10T22:59:31Z

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.

AsifKhan991 · 2023-02-11T06:10:29Z

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

cheotrix · 2023-02-13T10:16:01Z

@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

DharmikEC · 2023-03-13T10:25:24Z

@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.

R503 fingerprint module user manual-V1.2.2.pdf

Thank you.

Hi, i am trying to use the "get_direct_template" and the "show_saved_templates" but i have a problem with "get_template_buffer" function " if (finger.get_template_buffer(512, f_buf) == FINGERPRINT_OK) { //read the template data from sensor and save it to buffer f_buf". Can someone help me? Im using DY50 sensor with 256 packet len. and the template size is 512
