Hi friend
Buf id refers to 1 or 2 it depends on us where we generate the character file for the finger image.
Start page refers to the starting id where id starts from 0 hence it should be given as 0x00 0x00.
Page num refers to the starting page normally starts from 1. And single page consist of four template and there are 16 pages totally available.
But i’m not sure the definition for start page and the page num are correct it’s our assumption while working with our project and the search command provides the acknowledgement and returns the matched id.
