The wrapper implements OS dependent services for libweave


Build daemon examples

The example binaries land in the out/Debug/ directory build all of them at once:

make all-examples

...or one at a time.

make out/Debug/weave_daemon_light

Prepare Host OS

Enable user-service-publishing in avahi daemon

Set disable-user-service-publishing=no in /etc/avahi/avahi-daemon.conf

restart avahi

sudo service avahi-daemon restart

Control device with the cloud

Generate registration ticket

              "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_[XXXXX]_config.json
  • Note: in second and future runs, --registration_ticket options is not necessary anymore
  • Get your device id with
        sudo grep "cloud_id" /var/lib/weave/weave_settings_[XXXXX]_config.json
  • See a field called cloud_id like:
        "cloud_id": 0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d
  • Use this cloud_id for future communication with your device as its deviceId. It does not expire.
  • Verify device is up with Weave Device Managers on Android, Chrome or Weave Developpers Console, where you see this id listed right below the device name in device details section.
