Help with two fingerprints sensors

[giacomoverdi]

Hi!
is it possible to copy template from one sensor to another? Can you share an example?

Hello,
I haven't implemented and tested this. According to the datasheet it is possible to upload a template to the microcontroller/computer interfacing the sensor and to write a template stored on the microcontroller/computer back to the sensor. Look for the commands UpChar and DownChar in the datasheet of the sensor (https://github.com/hkieninger/fingerprint-R503/blob/main/R503_datasheet.pdf). Implementing this should not be too complicated and look similar to the function: R503::uploadImage. However, I don't know how well the template from one sensor will work on an other sensor. You will have to try that yourself, since I don't have a R503 around me at the moment. Let me know about your findings.

Best regards
Hans

Can you share with me an example?
