When " response = request.GetResponse()  "  the "response.StatusCode.ToString"="BadRequest"

i found the error is raise by

 ObexWebRequest.Connect

  "s.Connect(bep);"  

----- raise SocketException 10061

 BUT the error not always.... only sometimes ...

10061 is WSAECONNREFUSED.  Which means that the service couldn't be found on the peer device.  Is the OBEX server there always running?
 

So maybe the server can only handle a small maximum number of connections?

In fact , in every thread ,   i connet to a diffrent obexserver  @_@
