How can we get user thumb from finger print machine?

[SnguonTheara]

I see that we can get user information and attendant. How about user thumb? Can we set user information with thumb? Please help me.

I would like to know that too. Currently I have developed a microsoft vb.net system that is using the zk sdk, but I would like to migrate it to node.js. Can I listen to real time events (like the user fingerprint) using this package?

@SnguonTheara, @windgaucho

Unfortunately I couldn't find enough information regarding to transfer or query the fingerprint/face info from/to devices on the web.

[windgaucho]

What operations I am allowed to do using this package?

add/delete users to/from the device?

[bulentv]

No, unfortunately it is limited to read operations. Contributions are welcomed.

@bulentv This issue can be closed as the current pr #6 does this. Attn: @SnguonTheara

Thanks.

[windgaucho]

Thank you @shubhamoy !!!!!!!!!!!!!!!!!!

[windgaucho]

There is any docs about this new methods? :)

[shubhamoy]

@windgaucho You can check this commit. Apart from that feel free to post your query.

Last night I was trying to connect to F8 zk fingerprint. I tried to do a simple test with the code that you have in the readme.md and I was able to connect to my reader device, but I was getting an error that says that the gettime function does not exist, can you advice me about this error?

[shubhamoy]

Preliminary it appears that it's quite possible that the device's firmware might not be supporting the said method. Try checking the official documentation and codebase.

[windgaucho]

ok, I will do that and let you know, thanks for this library !!

@shubhamoy I can confirm that the method gettime works perfect in my device. I was doing ZK.getTime() instead of ZK.gettime(). Note that is not camel case, that was the error.

Now I am getting the following error when I execute the sample code that is in the readme:

var ZKLib = require("zklib");
    ZK = new ZKLib({
      ip : "192.168.5.11", 
      port : 4370,
      inport : 5200
    });
    ZK.connect( function() {
      ZK.getTime( function(err, t) {
        console.log("Device clock's time is " + t.toString());
        ZK.disconnect();
      });
    });

the error message is:

W20180301-19:21:20.112(-3)? (STDERR) TypeError: cb is not a function
W20180301-19:21:20.113(-3)? (STDERR)     at Socket.<anonymous> (/home/test-zklib/node_modules/zklib/zklib/zklib.js:39:7)

the error is fired when call the ZK.disconnect(). What I am doing wrong?
