Are you using prefix mode? You can only use it if both sides of the connection are using the "prefix" protocol.

You can use AsyncStreamsText class for text based streams (you can also use AsyncStreams in regular mode).

Hello Erel,
I too am playing with the example from flyingbag to send Hex data over TCP to a device that then passes it along to a serial port. I can send plain Ascii text successfully. Looking around I have found other using a byte array to send hex over serial and so on. I am not sure I understand how I can do that using what user enters into the textbox no matter the length of hex in the textbox. If a user enters "00 08 EF D4 01" or "02 7B 00 C8 00 03 EA" I would like it to be passed on as Hex no matter the number of bytes. If you could point me in the right direction I would appreciate it.

Thank

Ok I found a partial answer:

Sub txt_out_EnterPressed
      If Astreams.IsInitialized = False Then Return
    If txt_out.Text.Length > 0 Then

        Astreams.Write(Array As Byte(txt_out.Text))
     
          ToastMessageShow("Sending:" & txt_out.Text,False)
    End If
End Sub

This will work if am using bytes consisting of only digits such as "00 08 02" but I am using Hex that uses letters A-F and if I use any of those I get this error:

Any help would be great.

Thanks

I got it to work with the
ByteConverter library

Thanks
