Socket not connected error about go-coap

[gh0st42]

Oh, the successful connections were made using this: https://github.com/eclipse/californium.tools/tree/master/cf-browser

I created branch https://github.com/go-ocf/go-coap/tree/californium where I added tests for californium: californium_test.go.

For TCP:
go-coap has disabled blockwise by default for tcp connection - to enable it, you need to set client.BlockWiseTransfer to true.

example code:

  californiumServer = "californium.eclipse.org:5683"
  enable := true
  client := &Client{Net: "tcp", BlockWiseTransfer: &enable}`
  co, err := client.Dial(californiumServer)
  if err != nil {
	t.Fatalf("Error dialing: %v", err)
  }

  resp, err := co.Get("")
  if err != nil {
    t.Fatalf("Cannot post exchange")
  }

For UDP:
On Windows/Linux it is works. I dont' have MacOS to solve issue - it seems problem is in udp.go:WriteToSessionUDP -> If you replace line 62 in udp.go:
n, _, err := conn.WriteMsgUDP(b, correctSource(session.context), nil)
by
return conn.WriteToUDP(b, session.raddr)
is it helps you?
