"Un-Matched incoming response message" for /obs and Exception for /.well-known/core #6

Open expliotlabs opened 6 years ago

expliotlabs commented 6 years ago

Hi,

I have a very simple script to query californium.eclipse.org. Im querying two URIs

  1. /obs - This gives the Un-Matched incoming message log and keeps on retrying
  2. /.well-known/core - This throws an exception.

Is there anything Im doing wrong? I have tried with a different library (in ruby) and it works so it doesnt look like it is a server or connection issue.

Below are the details:

  1. script:

    !/usr/bin/python3

    from coapthon.client.helperclient import HelperClient

c = HelperClient(server=("californium.eclipse.org", 5683)) r = c.get("/.well-known/core") # The other query is for /obs print("r class {}".format(r.class.name))
