Eddystone
Eddystone is an open Bluetooth Low Energy (BLE) beacon protocol developed by Google for broadcasting small packets of data to nearby devices. It enables proximity-based interactions by transmitting URLs, telemetry data, or unique identifiers that can trigger actions in compatible apps. Unlike other beacon technologies, it supports multiple frame types for different use cases, such as Eddystone-URL for web links and Eddystone-TLM for sensor data.
Developers should learn Eddystone when building location-aware applications, such as retail experiences, museums, or smart environments, where devices need to detect and respond to physical proximity. It's particularly useful for scenarios requiring low-power, cross-platform beacon communication, as it works with both Android and iOS via Google's Physical Web or dedicated apps. Use cases include sending promotional offers in stores, providing exhibit information in museums, or tracking asset locations with telemetry data.
