I am trying to get the fingerprint template using the library, what I did up until now is i used the enroll example to store a fingerprint then i tried to read it using the Templates code, but i am getting the "Packet too long" error as you can see here.

The issue has been solved!

@brianrho suggested to change the BUFF_SZ value from 768 to 1536, and it's now working properly!

Thanks!
