Project type

Console App (.Net framework)

Code, where is happening

var response = request.GetResponse();

Where request is ObexWebRequest.

Error

System.Net.WebException
  HResult=0x80131509
  Message=GET failed with code: NotFound, Final
  Source=InTheHand.Net.Obex
  StackTrace:
   at InTheHand.Net.ObexWebRequest.DoGet(MemoryStream ms, WebHeaderCollection headers)
   at InTheHand.Net.ObexWebRequest.GetResponse()
   at // MY CODE HERE

Note

About two years ago we also used ObexWebRequest from InTheHand.Net.Personal. The code from this library now works successfully.

Assumption

Our device issues a status code to Obex requests: 0x20 | 0x80 That is Ok + Final Perhaps this is related to the error.
