Если потребителю нужна информация о какой бы то ни было услуге, ему для этого больше не нужно совершать никаких специальных действий — все, что нужно знать, через телефон сообщит ему незаметный BLE-датчик. Building Applications with iBeacon. A beacon transmits signals which allows another device to determine its proximity to the broadcaster. This is very new to Android phones, so expect the Beacon phenomenon to get bigger in the near term! Nearby Messages API Nearby Messages API is the API that allows different devices to publish and subscribe to messages, thus exchange data. The binary number is then written as a hexadecimal value which will be advertised. Когда местоположение определено, мобильное приложение может предпринять некоторые действия, например, показать соответствующую информацию. The only semi-useful results I've found have been that the BeaconManager app com. Другой альтернативой iBeacon является открытый протокол AltBeacon, созданный Radius Networks в 2014 году. Beacons are small bottle-cap-sized devices serving mostly for indoors navigation. IBeacon является торговой маркой компании Apple Inc.
Intro Beacons are Bluetooth-transmitters that send some information or advertising data that can be accepted by the smartphones and tablets within the range of the transmitter. For example, a smart bus stop can transmit route schedules, a shop can send discounts info, a museum can air the timetable of exhibitions, and so on. A message transmitted as a notification can contain a link to some web page. The starting point of the Beacons movement is considered to the development of iBeacons by Apple, announced in 2013. Beacons are the devices supporting the Bluetooth Low Energy technology. Their task is simple — serially send data packages advertisement packets. For example your company ID, retail store ID, etc. The GPS coordinates of a specific venue. This is a paragon of the signal strength. The paragon is the signal strength at the distance of 1 meter from the beacon. The iBeacon solution was only fit for iOS. Android had to use third-party libraries like Android beacon library. Eddystone In July of 2015, Google announced Eddystone- an open format for Bluetooth beacons. This technology is also compatible with iOS, as the packets format is similar to the iBeacon one. This is the same identifier, an analog of iBeacon UUID, Major, Minor. As for the rest, it acts similarly to the UID frame. This beacon is the base of the Physical Web technology. URL limit is 10 byte. It includes the Eddystone format, the monitoring and management system, and the APIs for beacons interaction like , , and Places API. Briefly, there is a Google cloud where all the beacons are registered by their identifiers. You can use a special Proximity Beacon API or a Beacon Tools app for this. After that you can bind data to the beacon, the so-called Attachments. With Beacon Dashboard you can not only register beacons, but also easily monitor and manage attachments via a usable interface. After this, you can interact with other beacons on the devices using Nearby Messages API and Places API. Places API is the UI, allowing binding Place ID metadata to the beacons. Nearby Nearby is the technology of network data exchange. This tool delivers content for users based on their location. Through this technology you can implement notifications connected to the place or a person. An important aspect is the interaction with the other devices. The API-UI of Nearby Connections API allows an app to easily discover other devices of the local network, connect, and exchange messages in realtime. Nearby is available starting from the Android version 4. Physical Web Physical Web is the ability to translate a regular URL from a beacon to the mobile devices with the help of Bluetooth Low Energy BLE technology. The Eddystone-URL packet is sent from a beacon and received by the devices with Bluetooth on. For example, there is a beacon in a store, sending notifications with links through bluetooth. Users within the reach of the beacon can access this notification and follow the link to the store website to see the entire catalog. Physical Web is like a QR-code, only a QR-code is passive and has to be found first, then you have to open an app with a camera, zoom in, get the URL and follow the link. Registering Beacons First, enter the Google console for developers, activate Nearby Messages API and Google Proximity Beacon API. Also, create an API key for the app working with Nearby Messages API. As a limitation for the key, select Application for Android. After that, enter the packet application name and the checksum of the SHA-1 certificate for. Has to be compatible with the representation WGS84 if not specified. The values have to be within the normalized scope. The ID value has to be base64 implementation of data. Beacons are presented as the source and can be registered by means of the beacons. A beacon can be registered simultaneously in a only one project at a time on Google Developers Console. An attempt to register a beacon the second time might lead to an error. As soon as the beacon is registered, its AdvertisedID field cannot be edited. After deactivation, the API will not be returning neither the bound data, nor the information about the beacon. In order to turn the beacon back into the working mode, invoke beacons. But you can easily assign a new ID to the beacon and re-register the beacon with a new ID. Attachments The generic data, called Attachments can be bound to the beacons. Currently, Attachments are only available for the project they were created in, with no availability for other projects. For example, aGVsbG8gd29ybGQh In order to figure out which namespaces are associated to which projects, you can invoke namespace. Attachments can up to 1024 byte long. You can use any string that matters for your application, for example, a bus stop ID, store location, structured data like JSON, or a link to an external database. You can manage beacons in Google Beacons Dashboard. The main dashboard window looks like this: You can also change the beacon configuration and add attachments here. Nearby Messages API Nearby Messages API is the API that allows different devices to publish and subscribe to messages, thus exchange data. Nearby Messages API is the part of. For message exchange, the devices must not be on the same network, but must be connected to the internet. In this case, the smartphone or tablet that is to receive messages must be connected to the internet. Nearby Messages API allows message exchange through Bluetooth, bluetooth Low Energy, Wi-Fi, and even ultrasound, but Bluetooth Low Energy allows to minimize energy consumption. Nearby Messages API is available on Android devices in the Google Play services library version 7. Setting up the project: In the build. Scanning is performed continuously until the app unsubscribes. Such a subscription is recommended to be used only when the application is active, usually as a response to some user actions. Emulating Beacons If for some reason there is no beacons available at hand, there is a way to utilize a third-party beacon emulators. Eddystone-TLM It works on top of the. The emulator device, for example a laptop must support Bluetooth v4 Bluetooth Low Energy. A app for Android. In Google Beacons Dashboard, add notification to the beacon. This notification will be distributed from the beacon to all the users within the reach of its signal with their bluetooth on and active internet connection.
