Hi Brian, you can close this I have worked it out and have it operational :) Big thanks Dans

Hi Dan, glad to hear you've got it working. Just in case, move_template()
in the templates
example will probably help here if you need to confirm steps. Good luck :-)

move_template() has all the answers :) Ty

Out of curiosity 1536 bytes is the template payload it seems. Are there any pointers on how I can display to an actual tft the fingerprint images based on the array data. Would be a really nice addition. I am using the tft_eSPI library. Have you experimented with images recreation on tft displays before?
from fpm.
Yeah, I did this once, some years back. Once you have a way to read the image from the sensor (from the examples), you can potentially write said image to a display simultaneously.
As usual, It will take a few seconds though, to read the image from the sensor since the UART transport isn't the fastest. Keep in mind, what you have there is the template size, not the image size which is usually much greater at ~37 kB for 256x288 "4-bit" grayscale, depending on your sensor. You can't get any sort of image from the template data alone, since that would require interpreting it -- completely infeasible without info from the manufacturer who won't be telling you anything. And I'm not sure even they can get a useful image from the template, being a condensed record of your fingerprint's relevant characteristics.

Just to update this issue -- finally added an example for this (image_to_tft
).
