Confirmation code =57H, The second acquisition was successful
Confirmation code =24H, repeat to enroll( the template is exist)
6.3.7 Auto search
Description: Send the instruction, the module will complete a serial of operation. include: capture fingerprint,
generate features, and search
Input Parameter: wait time for press+ start ID+ search numbers
Return Parameter: Confirmation code (1 byte)

Wait time for press finger is the max wait time for waiting . if no finger press inside the wait time, it will
return no finger. The value range from 1 to 255, The higher the value, the more time, for 70serials Usually
use 54
（
0x36
）
The corresponding time is 3.5seconds, the other time is below:
Value Wait time(seconds) Value Wait time(seconds)
31(0x1f) 2 62(0x3e) 4

Note: Confirmation code =00H, success to search
Confirmation code =09H, No search
Confirmation code =02H, no finger on sensor
Confirmation code =06H,fail to generate character file due to the over-disorderly fingerprint image;
Confirmation code =07H,fail to generate character file due to lackness of character point or over-smallness of
fingerprint image
Confirmation code = 0x22 , residual finger
Confirmation code = 0x23 , there is not valid template
6.3.8 Search (with residual judge
）
Description: use the feature of CharBuffer1 or CharBuffer2 to search. If searched, then return the id matched.
The difference between the command and Search
（
instruction code is 04H
）
is that the return code is different.
