make all-examples

...or one at a time.

make out/Debug/weave_daemon_light

Prepare Host OS

sudo service avahi-daemon restart

Control device with the cloud

Generate registration ticket

• Go to OAuth 2.0 Playground
• "Step 1": Paste https://www.googleapis.com/auth/clouddevices and click to "Authorize APIs"
• "Step 2": Click "Exchange authorization code for tokens"
• "Step 3": Fill the form:
  • HTTP Method: POST
  • Request URI: https://www.googleapis.com/weave/v1/registrationTickets
  • Enter request body: {"userEmail": "me"}
  • Click "Send the request", a ticket id will be returned in

            {
              "userEmail": "user@google.com",
              "kind": "weave#registrationTicket",
              "expirationTimeMs": "1443204934855",
              "deviceId": "0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d",
              "creationTimeMs": "1443204694855",
              "id": "93019287-6b26-04a0-22ee-d55ad23a4226"
            }

• Note: the ticket "id" is not used within 240 sec, it will be expired.

Register device to cloud

• Copy the ticket "id" generated above: 93019287-6b26-04a0-22ee-d55ad23a4226
• Go to terminal, register and start the daemon with

        sudo out/Debug/weave_daemon_sample --registration_ticket=93019287-6b26-04a0-22ee-d55ad23a4226

• See something like:

        Publishing service
        Saving settings to /var/lib/weave/weave_settings.json

• Note: in second and future runs, --registration_ticket options is not necessary anymore
• Get your device id with

        sudo cat /var/lib/weave/weave_settings.json

• See something like:

        ...
        "device_id": 0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d
        ...

• Use this device_id for future communication with your device. It does not expire.
• Verify device is up with Weave Device Managers on Android, Chrome or Weave Developpers Console
