Password verification fails

I'm using a GROW R311. Checking the default password never passes, but nevertheless, the functions work further: for example, enrolling new fingers you can do.

Command string = verpwd
First param = ffffffff

Sent packet = EF-1-FF-FF-FF-FF-1-0-7-13-FF-FF-FF-FF-4-17
txInstructionCode = 13
txDataBufferLength = 4
txPacketLengthL = 7

Reading response.
Checksums match success.
Received = 0-1D
Received L = 1D
Calculated = 0-1D
Calculated L = 1D
Received packet = EF-1-FF-FF-FF-FF-7-0-3-13-0-1D
Data stream = none
rxConfirmationCode = 13
rxDataBufferLength = 0
rxPacketLengthL = 3
rxPacketLength[] = 0-3
Password is not correct.
Current Password = FFFFFFFF
rxConfirmationCode = 13
response == 19

Export fingerprint data

Hi,
Thanks for the great work you are doing writing this library.
Could you please advise how to export templates to some external database in order to have a backup in case of sensor module fault ?
Thanks in advance.
