Overview

The wrapper implements OS dependent services for libweave

Building

  • prepare environment examples/prerequisites.sh
  • build daemon examples/build.sh
  • binaries for daemon are in the directory out/Debug/

Prepare Host OS

enable user-service-publishing in avahi daemon file: /etc/avahi/avahi-daemon.conf check: disable-user-service-publishing=no restart: sudo service avahi-daemon restart

Acquire Registration Ticket

Goto https://developers.google.com/oauthplayground/

  • “Step 1”, paste to “Authorize APIs” with https://www.googleapis.com/auth/clouddevices click “Authorize APIs”, then “Allow” to get an “authorization code”
  • “Step 2”, “Exchange authorization code for tokens”
  • “Step 3”, obtain a registration ticket for your new weave device HTTP Method: POST Request URI: https://www.googleapis.com/weave/v1/registrationTickets Enter request body: { “userEmail”: “me” } then “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

you should 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 you should see ... “device_id”: 0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d ...

    this device_id shall be used for future communication with your device. it does not expire and no need to register.

  • verify device is up with Weave Device Manager at android: https://play.google.com/apps/testing/com.google.android.apps.weave.management chrome: https://chrome.google.com/webstore/detail/weave-device-manager/pcdgflbjckpjmlofgopidgdfonmnodfm [need your whitelisted EAP account]

Send Command to the Daemon

  • go to the oauthplayground used for registration ticket command in “Step 3”, send command with 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 history with oauthplayground Similar to “Acquire Registration Ticket” section in this document, except in “step 3”, do:

    HTTP Method: GET [not POST anymore] Request URI: https://www.googleapis.com/weave/v1/commands?deviceId=0f8a5ff5-1ef0-ec39-f9d8-66d1caeb9e3d

    “Send the request”, you get all of the commands executed on your device, find something like “kind”: “weave#command”, “name”: “_sample.hello”, ...
