Overview

The wrapper implements OS dependent services for libweave

Building

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

• 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_[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.

Send Command to the Daemon

• 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/commands
  • Enter request body:

        {
          "deviceId": "0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d",
          "name": "_sample.hello",
          "component": "sample",
          "parameters": { "name": "cloud user" }
        }

• “Send the request”, you command will be “queued” as its “state”
• Verify the command execution observing daemon console logs
• Verify the command usign Weave Developpers Console
• Verify the command history with 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: GET
  • Request URI: https://www.googleapis.com/weave/v1/commands?deviceId=0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d
  • Click “Send the request”, you get all of the commands executed on your device.
