[51] fingerprint - acknowledgement packet

shanthi rani · Nov 2, 2013

hi..
can any body help me in my project.
I have SFG r305 finger print module, and i want to know whether i have to write code for acknowledge packet in order to get acknowledgement status...

Provide datasheet of fingerprint module.

Pls do find find the attached data sheet

Module acks. PC or micro doesn't have to ack.

PHP:

Upon receipt of commands, Module will report the commands execution status and results to upper 
computer  through  acknowledge  packet.  Acknowledge  packet  has  parameters  and  may  also  have 
following  data  packet.  Upper  computer  can’t  ascertain  Module’s  package  receiving  status  or 
command execution results unless through acknowledge packet sent from Module. Acknowledge 
packet includes 1 byte confirmation code and maybe also the returned parameter.

k can u pls give me the sample code for sending commands to finger print.

jayanth.devarayanadurga · Nov 2, 2013

I don't have any sample code.

This is an example command for verifying password. Change password bytes accordingly. Send the hex values in sequence from UART to finger print module through Half-Duplex Asynch Serial communication. It should ack the verify password command. Send me the ack data which it gives. If possible send me Team Viewer 8 ID and pass. I will connect to your system.

thnk u..
so aftr sending these commands to fingerprint,
how to know its acknowledgement status...., do i need to write commands to receiv its status r by default it generates the result...?
please give me some idea

jayanth.devarayanadurga · Nov 2, 2013

The previous code had errors. You have to write code like this... There are still many functions to be written. Module sends ACK. You have to use UART receive interrupt to receive ACK data and then extract confirmation code from ACK packet. Depending upon it you have to take decisions.

thank u v much sir...

There is a mistake in Checksum calculation. Remove header and address from the findChecksum() function.

This is incomplete code. The code inside ISR has to be completed yet. Only the values used in the if() condition change according to the length of ACK packet.
