This is upsetting.
Maybe you can help find the right direction.
Sorry for my English, I'm from Ukraine ...
My experience in programming arduino is not great, so many problems and questions arise. The challenge now is to clone the fingerprint database from one scanner to another. Having studied this topic, I managed to get a response from the scanner with the data packet, but they do not look like they showed here. The method of receipt as in message #24.
I use Arduino Nano + R307 fingerprint scanner. To send messages, your sketch from message # 12 and CoolTerm. The result is in the attached file. I can’t understand how to extract the data necessary for cloning from it (((

I never did use have access to the same doc as you, as highlighted above... sorry can’t help
I'm at a standstill, maybe someone will point the right direction.
I do a fingerprint scan, convert it to a template with the RegModel command. The documentation says - "generate a template which is stroed back in both CharBuffer1 and CharBuffer2". As I understand it, the contents of the buffers should be the same. Having executed the comparison command - Match, I get confirmation of this. But if I try to output the contents of the buffers to the console with the command - UpChar, I see completely different data. Moreover, if I ask several times in a row to display the contents of the buffer neither doing anything else with the scanner, I get different values ...
In the attached file, data output from buffer No. 1 and several conclusions in a row from buffer No. 2.
