B4A Library [B4X] SP IFStatus - Check if interface status (WiFi, cell network data or LAN) has enabled or disabled

  • IFStatus
    • Events
      • SocketStarted (Port As Int)
        Triggers when the socket starts
      • SocketClosed
        Triggers when socket closes
      • ConnectionStatusChanged (IPStatus As tpeIPs)
        Triggers when there is a change in the connection. Returns a tpeIPs type variable. See details below
      • Error (Msg As String)
        Trigger when an error occurs, they can be the following:
        • Socket not initialized.
        • The IP format is not valid. Includes IPv4 or IPv6
        • Can't initialize socket.
        • Can't initialize socket on port NUM_OF_PORT
        • Socket is already initialized on port NUM_OF_PORT
    • Types
      • tpeIPs (IsConnected As Boolean, ConnType As String, IP As String)
        • IsConnected: True or False
        • ConnType: NONE (B4X), WIFI (B4A/B4I), CELL (B4A/B4I) or LAN (B4J)
        • IP: Valid IPv4 or IPv6
    • Fields
      • Tag As Object
        Default: Null (It is always valuable to have a Tag field ;))
      • IPs As tpeIPs
        Default: IsConnected = False, ConnType = "NONE", IP: "127.0.0.1"
      • blnIPv4IsValid As Boolean
        Default: false
      • blnIPv6IsValid As Boolean
        Default: false
    • Methods
      • Initialize (CallBack As Object, EventName As String)
        Initializes the object. Add parameters to this method.
      • Start (Port As Int)
        Start the socket on the desired port
        IMPORTANT: The number can be 0 or one greater than or equal to 1025 up to 65535.
        Search on         this list of ports for one that is available and does not conflict with another service
      • GetIfChanged (ForceRaiseStatus As Boolean)
        Update IPs variable
        Default: False. If ForceRaiseStatus is True, raise event ConnectionStatusChanged whether the IP has changed or not
      • Close
        Close socket
Change log:
  • 1.00
    • Release

In release mode, it works as long as wifi or cellular connection is there . However, once there is no connection, it shows :
Connection:NONE
Local IP:127.0.0.1
Click to expand...
After that, even if I connect to wifi or cellular, the status does not change. It still shows "NONE"
I use the following routine to see the connection. What should I modify to see the connections again?:
B4X: 
Private Sub btnCheck_Click
    If Not (ifSts.IPs.IsIfConnected) Then
        ifSts.Start(0)
    Else
        ifSts.GetIfChanged(True)
        lbl_type.Text = "Connection: " & ifSts.IPs.ConnType & CRLF & "Local IP: " & ifSts.IPs.IP
    End If
End Sub
