Device Discovery is not working in vb.net #26

Closed patelonline closed 7 years ago

patelonline commented 7 years ago

Hi Jeff,

I am using XBee Library in my vb.net winforms application. I am using 2 XBee devices(S2C) I have a coordinator in API mode(1). and other 2 XBEEs are in AT mode. While I use XCTU all devices are scanned properly, but while I use this .net library it triggers event randomly (nodeDiscovered)!! I have a debug info here which i am getting on console while I Discover. So everytime while discovery debug shows that devices are getting discovered but event is not triggering everytime!!

**Code*** `Imports System.IO.Ports Imports BinarySerialization Imports XBee

Public Class FrmMain Dim WithEvents controller As XBee.XBeeController

Private Sub contoller_NodeDiscovered(sender As Object, e As NodeDiscoveredEventArgs) Handles controller.NodeDiscovered
    Console.WriteLine("Discovered {0}", e.Name) 
End Sub

Private Sub contoller_SampleReceived(sender As Object, e As SourcedSampleReceivedEventArgs) Handles controller.SampleReceived
    Console.WriteLine("Sample recieved: {0}", e)
End Sub

Private Async Sub FrmMain_Load(sender As Object, e As EventArgs) Handles Me.Load
    BtnDiscover.Enabled = False
    Try
        controller = Await XBeeController.FindAndOpenAsync(SerialPort.GetPortNames(), 9600)
        If controller.IsOpen Then
            BtnDiscover.Enabled = True
        End If
    Catch ex As Exception
        Console.WriteLine(ex.Message & ex.StackTrace)
    End Try
End Sub

Private Async Sub BtnDiscover_Click(sender As Object, e As EventArgs) Handles BtnDiscover.Click
    If Not controller Is Nothing Then
        If controller.IsOpen Then
            Await controller.DiscoverNetworkAsync()
            Console.WriteLine("Node Discovery started")
        End If
    Else
        MsgBox("no Controller attached")
    End If
End Sub

Private Sub controller_FrameMemberSerializing(sender As Object, e As MemberSerializingEventArgs) Handles controller.FrameMemberSerializing
    Console.WriteLine("S-Start: {0}", e.MemberName)
End Sub

Private Sub controller_FrameMemberSerialized(sender As Object, e As MemberSerializedEventArgs) Handles controller.FrameMemberSerialized
    Dim value = If(e.Value, "null")
    Console.WriteLine("S-End: {0} ({1})", e.MemberName, value)
End Sub

Private Sub controller_FrameMemberDeserializing(sender As Object, e As MemberSerializingEventArgs) Handles controller.FrameMemberDeserializing
    Console.WriteLine("D-Start: {0}", e.MemberName)
End Sub

Private Sub controller_FrameMemberDeserialized(sender As Object, e As MemberSerializedEventArgs) Handles controller.FrameMemberDeserialized
    Dim value = If(e.Value, "null")
    Console.WriteLine("D-End: {0} ({1})", e.MemberName, value)
End Sub

End Class`

Please Help me with this issue. Thanks

Yes, there appears to be an issue with the S2C. Unfortunately I didn't have the part and have just recently ordered it. Once it gets here I will work on the bug. Thanks!

I just pushed 4.3.1. Please try it and see if you have better luck, thanks.
