It is important to note that Eddystone uses a 0 meter calibration value and not a 1 meter calibration value like AltBeacon and To measure the signal strength output by the beacon. Calibration means using a mobile app like RadBeacon Android Proper power calibration value for its transmitter power settings. In order to get the best distance estimates possible, it is important to calibrate your beacon and configure it with the On the Received Signal Strength Indicator (RSSI) as measured by a mobile device. ![]() This value can be used as an input to estimate the distance of the beacon based The third field in the Eddystone-UID frame is the power calibration field, which is a one byte signed integer of theīeacon transmitter strength in dBm at zero meters. IBeacon use three fields (Proximity UUID, major and minor) Power calibration Eddystone beacons are identified by two fields (namespace and instance) whereas AltBeacon and Note that this differs from the major/minor identifier scheme used by AltBeacon and iBeacon formats, which use Because the field is 48 bits long, there are 2^48 = 281 trillion combinations. Each beacon should be configured with a different This is a six byte identifier intended to uniquely identify the beacon. You can use tools like RadBeacon Android to generate namespace identifiers from both URLs and UUIDs, and configure the field directly into the beacon. Because this technique uses a one way hashingĪlgorithm, there is no way to convert the namespace id back to a URL. Name you own like into a unique namespace id. So you can algorithmically convert a domain Google also prescribes a second technique for generating a UID out of a URL. Below is an example of such a conversion. Organizational identifier for both formats. If you already have an iBeacon Proximity UUID assigned for your company or organization, allowing you to use an equivalent ![]() Namespace identifiers are only 10 bytes, you drop the middle six bytes from the UUID. But because standard UUIDs are 16 byte identifiers and You can generate a namespace identifier with a UUID generator. This 10 byte identifier is typically used to signify your company or organization, so you know it is your beacon. This is the primary Eddystone frame that consists of three fields, two of which are identifiers: Namespace identifier Beacons can be configured to send out more than one of these frames at the Of the frames depending on your application. These three frames serve different purposes, and you can decide to use one or more To be sent out by the same physical beacon. What is Eddystone?Įddystone differs from other beacon formats like iBeacon or AltBeacon in that it defines multiple frames that are designed This allows you to use a single library to ![]() The library also supports detection of proximity beacons using a variety of other formats, including the open sourceĪltBeacon and proprietary beacons from other big Silicon Valley companies. Support for Eddystone-EID is available in version 2.9-beta1. Eddystone-UID (identifier frame), Eddystone-TLM (telemetry frame) andĮddyston-URL (URL frame) are all detected and decoded. ![]() Ranging updates while they are in the vicinity. The library will wake up your app when it detects Eddystone-compatible beacons in the background and provides regular Library versions 2.3 and higher provide full support for Eddystone™, the new beacon format from Google.
