FacePass problem with restore face template [BUG]

[salvsena]

Hi,
have a problem with restore face template

This work well, get and save the template:
' save face template of user 1
Dim Face As Byte() = Await device.GetFaceTemplate(1)
File.WriteAllBytes("Face-"1" & ".anv", Face)

This not work, i read file and put the template:
Dim BB As Byte() = File.ReadAllBytes("Face-"1" & ".anv")
Await device.SetFaceTemplate(1, BB)

error is: "Device is not connected."

Someone has same problem ?

With fingerprint all work well !

Thanks !!

How are you connecting to the device? The error you are seeing is not coming from SetFaceTemplate but from the underlying SendCommand, and the first check is to ensure the socket is actually connected. In fact, it should error even if you replace with any other command.

Anviz/Anviz.SDK/AnvizStream.cs

Lines 78 to 83 in 7339b34

	public async Task<Response> SendCommand(Command cmd)
	{
	if (!DeviceSocket.Connected)
	{
	throw new Exception("Device is not connected.");
	}

yes is connected because before i do:
Dim Seriale = Await device.GetDeviceSN

and i receive the seriale, afeter i do:
Dim BB As Byte() = File.ReadAllBytes("Face-1.anv")
Await device.SetFaceTemplate(1, BB)

and receive:
Device is not connected.

Can you help me ?

Can you try with a simple program that connects and only calls SetFaceTemplate, without GetDeviceSN or anything else?

yes also in this way not work:

Dim BB As Byte() = File.ReadAllBytes(Face-1.anv")

Dim rr As AnvizDevice = Await manager.Connect(item.tooltip)
Await device.SetFaceTemplate(1, BB)

But you have used this command successful ?

Not me personally as I don't have any FacePass enabled device, but other users have reported that it works.

To further debug, remove the nuget package, download this git repository, add the project to your solution, add the project reference and step debug the code to see exactly where it is failing.

i have tryed, but nothing change:

Private manager As New AnvizManager()
Private device As AnvizDevice

Private Async Sub NuovaSDK_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    manager.Listen(5010)

    device = Await manager.Connect("192.168.1.58")


   ' this work well
    'Dim Face As Byte() = Await device.GetFaceTemplate(1)
    'File.WriteAllBytes("Face-1.anv", Face)

   ' here have error --> System.Exception: 'Device connection lost.'
    Dim BB As Byte() = File.ReadAllBytes("Face-1.anv")
    Await device.SetFaceTemplate(1, BB)


    manager.StopServer()

End Sub

You need to step into that function
