    I used this code for data send with UDP protocol.

    its work and i recive data with host.
    But I closed Host application, and sender code result not change same read logs ("packet send")
    How can i check send status?

    Wemos board code:
    If udp.BeginPacket(sip,54321Then
    Dim x As String
    If udp.SendPacket Then
    Log("packet send")
    End If
    Log("Service Problems")
    End If

    There isn't any other information available. You never know with UDP whether the sent packet was received (it is a connectionless protocol).

    I never use UDP, TCP is better, generates more traffic, but it's a lot safer. I connect, send info and if no other activity is needed, sconnect. Protocolo takes care of anything.
