I’m working on a project using the GT-521F32 fingerprint scanner, i want to store the templates in a database in my computer rather than have them stay in the fingerprint scanner’s memory. While I am able to get the templates from the fingerprint scanner and store it in my computer, I am unable to set the templates back to the fingerprint scanner. I am currently using RealTerm to send commands to the fingerprint scanner.
First, I would get the template from ID 1
Send command (Get template from ID 1):
0x55 0xAA 0x01 0x00 0x01 0x00 0x00 0x00 0x70 0x00 0x71 0x01
Output:
55 AA 01 00 00 00 00 00 30 00 30 01 (Acknowledge)
5A A5 01 00 …(498 bytes of template data)… FD DF (Data Packet)
I would then delete the template in ID 1, and set the template that I got from ID 1 in ID 2
Send Command (Set template to ID 2):
0x55 0xAA 0x01 0x00 0x02 0x00 0x00 0x00 0x71 0x00 0x73 0x01
Output:
55 AA 01 00 00 00 00 00 30 00 30 01 (Acknowledge)
Send Command (Data packet):
0x5A 0xA5 0x01 0x00 …(former ID 1 template data)… 0xFD 0xDF
Doing this doesn’t result in an acknowledgement packet
Even when using the demo program provided, when I use the setTemplate option, it just results with “Communication error”. How do I set templates from my computer to the fingerprint scanner’s memory?
