Tools used in Hackathon

CoAP clients

CoAP shell

Interactive, command line interface for interacting with CoAP enabled servers: https://github.com/tzolov/coap-shell

Copper CoAP client

This requires old version (55) of Firefox.

For Mac or for windows

Steps:

1. Ensure to start offline (no Internet connection!) and disable auto updates
2. Open about:config
3. Search browser.tabs.remote.autostart and browser.tabs.remote.autostart.2
4. Set both to false
5. Open preferences
6. Go to advanced -> update
7. Check "never check for updates (not recommended: security risk)"
8. Go back on-line
9. Go to tools->add-ons
10. Search for "Copper"
11. Install, restart
12. Done

And do not use this version of Firefox for anything else than Copper since it is likely to have security risks!

Proto setups

Lights

Philips Hue light (as seen in the remote participation Jitsi): http://31.130.239.203/

Username: 14NaBIsEyoNSdU21KnsQHZzTUToNVWYQWhmj4xIG

For example, to turn the light on: curl -X PUT http://31.130.239.203/api/14NaBIsEyoNSdU21KnsQHZzTUToNVWYQWhmj4xIG/lights/1/state -d '{"on": true}'

For details, see Hue API

Debug web app: http://31.130.239.203/debug/clip.html

LwM2M WoT TD mapping proto

Idea: Make WoT servient interact with standard LwM2M client by generating WoT TD(s) out of LwM2M clients registered to LwM2M server. Annotate the TD with iotschema.org semantics.

See resources above for TDir and LwM2M MS addresses.

Leshan Client: TBD

Some Exposed Things

These are reachable over the internet except for the hue light, which is an example of a TD that can be used by node-wot
