Hi. I am using zk 40 but I can´t conect to the device, someone has a solution?

[noeurphireak]

define( 'CMD_ACK_OK', 2000 );
I have a question in checkValid() function for variable $command that receive the packet which return more then 2000 that's okay or not ?
I tested with this model https://www.zkteco.com/en/product_detail/G4.html
I wonder why this $zk->connect() always return false but actually it connected and I can get the user and attendant data from that device. I did debug in checkValid() and the return packet is 2005. Because in checkValid() return true unless $command == CMD_ACK_OK.
