I want to greet you and congratulate you for this libery and for the great contribution to the community, I hope that you and your whole family are doing well and that success follows you. I politely request your help, when starting the tests it worked very well, but over time the following error is displayed:

[2022-10-29 11:51:01] production.ERROR: array ( 'Archivo: ' => 'C:\xampp\htdocs\project\vendor\rats\zkteco\src\Lib\ZKTeco.php', 'Linea: ' => 63, 'Codigo: ' => 0, 'Mensaje: ' => 'unpack(): Type H: not enough input, need 1, have 0',

Your help, with this particular and I am ready to give you all my help or possibly I am wrong about something.

As a background, I can tell you that I have it deployed in XAMPP and that I am using PHP 7.4 as the Windows 10 operating system and previously I had it in Linux Ubuntu 20 where it kept the same error.

Stay tuned.

God bless us and prosper the fruit of our work, always.

Dear Raihan,

Dios te bendiga, grandemente..!

I did what you told me, but without result, for this in my business model I have 2 zkteco devices, one for input and one for output so you can check that both responded to the ping, but when I tried to do $zk->connect() the output only responded true and the input false, I also eliminated the scheduled task that updates the markings every 1 min and I also did not realize that it did not do $zk->disconnect(); So I turned off the computers and there it answered $zk->connect() true, there are three possibilities:

1.- The device is frozen by receiving every 60 seconds a udp request to port 4370 making it always busy. 2.- The device has too many attendance that it is impossible to download it and resolve another request. 3.- That within my code I was not closing the connection after downloading attendance. 4.- I found a computer on the machine that was a server that uses port 4370, so I eliminated this service. 5.- All the previous alternatives.

So I did all these things, and it finally worked. I am very happy and thank you very much for quicky response.

Thanks You.!
