Beacon The Google Way

  1. 1. Beacon The Google Way www.letsnurture.com
  2. 2. Just like lighthouses have helped sailors navigate the world for thousands of years, electronic beacons can be used to provide precise location and contextual cues within apps to help you navigate the world. For instance, a beacon can label a bus stop so your phone knows to have your ticket ready, or a museum app can provide background on the exhibit you’re standing in front of. Today, we’re beginning to roll out a new set of features to help developers build apps using this technology. This includes a new open format for Bluetooth low energy (BLE) beacons to communicate with people’s devices, a way for you to add this meaningful data to your apps and to Google services, as well as a way to manage your fleet of beacons efficiently.
  3. 3. Beacons are taking over the world
  4. 4. Eddystone: an open BLE beacon format Working closely with partners in the BLE beacon industry, we’ve learned a lot about the needs and the limitations of existing beacon technology. So we set out to build a new class of beacons that addresses real-life use- cases, cross-platform support, and security. At the core of what it means to be a BLE beacon is the frame format—i.e., a language—that a beacon sends out into the world. Today, we’re expanding the range of use cases for beacon technology by publishing a new and open format for BLE beacons that anyone can use: Eddystone. Eddystone is robust and extensible: It supports multiple frame types for different use cases, and it supports versioning to make introducing new functionality easier. It’s cross-platform, capable of supporting Android, iOS or any platform that supports BLE beacons. And it’s available on GitHub under the open-source Apache v2.0 license, for everyone to use and help improve.
  5. 5. By design, a beacon is meant to be discoverable by any nearby Bluetooth Smart device, via its identifier which is a public signal. At the same time, privacy and security are really important, so we built in a feature called Ephemeral Identifiers (EIDs) which change frequently, and allow only authorized clients to decode them. EIDs will enable you to securely do things like find your luggage once you get off the plane or find your lost keys. We’ll publish the technical specs of this design soon.
  6. 6. Eddystone for developers: Better context for your apps Eddystone offers two key developer benefits: better semantic context and precise location. To support these, we’re launching two new APIs. The Nearby API for Android and iOS makes it easier for apps to find and communicate with nearby devices and beacons, such as a specific bus stop or a particular art exhibit in a museum, providing better context. And theProximity Beacon API lets developers associate semantic location (i.e., a place associated with a lat/long) and related data with beacons, stored in the cloud. This API will also be used in existing location APIs, such as the next version of the Places API.
  7. 7. www.letsnurture.com Eddystone for beacon manufacturers: Single hardware for multiple platforms Eddystone’s extensible frame formats allow hardware manufacturers to support multiple mobile platforms and application scenarios with a single piece of hardware. An existing BLE beacon can be made Eddystone compliant with a simple firmware update. At the core, we built Eddystone as an open and extensible protocol that’s also interoperable, so we’ll also introduce an Eddystone certification process in the near future by closely working with hardware manufacturing partners. We already have a number of partners that have built Eddystone-compliant beacons.
  8. 8. www.letsnurture.com Eddystone for businesses: Secure and manage your beacon fleet with ease As businesses move from validating their beacon-assisted apps to deploying beacons at scale in places like stadiums and transit stations, hardware installation and maintenance can be challenging: which beacons are working, broken, missing or displaced? So starting today, beacons that implement Eddystone’s telemetry frame (Eddystone-TLM) in combination with the Proximity Beacon API’s diagnostic endpoint can help deployers monitor their beacons’ battery health and displacement—common logistical challenges with low-cost beacon hardware.
  9. 9. www.letsnurture.com Eddystone for Google products: New, improved user experiences We’re also starting to improve Google’s own products and services with beacons. Google Maps launched beacon-based transit notifications in Portland earlier this year, to help people get faster access to real-time transit schedules for specific stations. And soon, Google Now will also be able to use this contextual information to help prioritize the most relevant cards, like showing you menu items when you’re inside a restaurant.
  10. 10. We all want to make beacons useful even when a mobile app is not available; to that end, the Physical Web project will be using Eddystone beacons that broadcast URLs to help people interact with their surroundings. Beacons are an important way to deliver better experiences for users of your apps, whether you choose to use Eddystone with your own products and services or as part of a broader Google solution like the Places API or Nearby API. The ecosystem of app developers and beacon manufacturers is important in pushing these technologies forward and the best ideas won’t come from just one company, so we encourage you to get some Eddystone-supported beacons today from our partners and begin building!
  11. 11. Receiving the message After the message is sent, the system receives the message throughonMessageReceived(). Based on the requirements of your game, you can override this method to update game information such as player scores, on-screen drawings, or the current player's turn. The following code snippet shows how to override this method to handle received messages: @Override public void onMessageReceived(String endpointId, byte[] payload, boolean isReliable) { // Implement parsing logic to process message }
  12. 12. Coming Soon The Nearby Messages API will be available in Google Play services 7.8. This site will be updated with the complete API documentation when the new version is available. https://developers.google.com/nearby/
