issue with sunlight

[irpcpro]

hi . i use ZFM60 for my project and i use from your library for this module. everything is Ok but i have a issue ... when module is under the sunlight , the module want to try read finger and return error .. without put finger on it . it means the Ghost try to put his finger :))) but system cannot recognized and return error (not found in database) . but into building everything is ok .

how can i fix the sunlight issue ? is this for security level ? how can i change the security level on this line of library ? is this line for change security ?

src/FPM.h:134 /* security levels */ enum { FPM_FRR_1 = 1, FPM_FRR_2, FPM_FRR_3, FPM_FRR_4, FPM_FRR_5 };

In order to know if security levels is even relevant to your issue, you need to first provide your sketch and also the Serial Monitor output. I think you're likely not using the getImage()/Image2Tz() API properly.

its true, all code works good on the building for days .... i try again and it seems this part : p = finger.getImage(); detect the sunlight as a fingerprint shadow ...

how can i change security ZFM60 by set parameter ???? on the examples just is setting for changing baud rate ..
