I have ZKTeco F-22 bio device, few weeks before i connected and getted datas from device successfully, right now i cant connect to device, when im trying to connect to device im getting an “-201” error which in documentation means (device is busy). I tried to restart/reset device, but result is 0. Im in same network with device (and i can ping the device from cmd), this is my configuration:
-
Device Network settings:
-
PC network settings:
Im using this easy to use wrapper library. My code is:
static void Main()
{
AccessPanel device = new AccessPanel();
bool conState = device.Connect("192.168.0.222", 4370, 123, 5000);
if (conState)
Console.WriteLine("Connected successfully.");
else
Console.WriteLine($"Cant connect ({device.GetLastError()}).");
device.Disconnect();
Console.ReadLine();
}
