Hi Ian,

Thanks for the reply. Actually at the end of my post I mention that I am currently using HTTPWebRequest, but the result is the same i.e. I only see the header info in the buffer received. So as a workaround I am using the UserAgent property and setting that value to the degrees I want my servo to turn to since I can see that property in the heading.

The code using WebRequest came directly from here:

https://msdn.microso...(v=vs.110).aspx

In that example a long string value is put in a field called postData and sent to the web server. It is that string that I would like to Debug.Print on the Netduino 3 end.

I read through the post you referenced. I also downloaded the XivelyClient you mentioned, put it in a quick console app, and altered it to send to my Netduino 3. The result is also the same. All versions, WebRequest, HttpWebRequest, and XivelyClient's HttpWebRequest, successfully enter the Netduino 3 code listening for requests (ListenForRequest above) . I just don't seem to be able to tweeze out the data value I purposefully put in the byte array. The buffer received only prints:

POST / HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: 10.0.1.240
Content-Length: 3
Expect: 100-continue
Connection: Keep-Alive

Thanks again,

Brian

 public ActionResult PostDegrees(string degree)
        {
            WebRequest request = WebRequest.Create("http://10.0.1.240"); // my N3 static IP
            request.Method = "POST";
            string postData = degree; //Degree to turn servo.
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = byteArray.Length;
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();
            return null; //Probably should be something else.
        }

                    int bytesReceived = clientSocket.Available;
                    if (bytesReceived > 0)

                        byte[] buffer = new byte[bytesReceived];
                        int byteCount = clientSocket.Receive(buffer);
                        string request = new string(Encoding.UTF8.GetChars(buffer));

            }

I'm moving a slider on a web page with a numeric range of 0-180, which is the range of motion of my servo connected to my Netduino 3. I just seem to be missing some important concept in reading the degree value that I believe I'm sending. At the moment my workaround is changing the sending code from WebRequest to HTTPWebRequest and stashing the degrees in the user agent property. This works great but just feels oh so wrong. Any insight/suggestions would really be appreciated.
