Eddystone-UID
An open Bluetooth Low Energy beacon protocol specification from Google for proximity messaging.
What is Eddystone-UID?
Eddystone is an open protocol specification from Google that defines a Bluetooth Low Energy (BLE) message format for proximity beacon messages. It enables devices to broadcast structured data frames that can be detected by nearby smartphones, supporting applications like location-based notifications, asset tracking, and contextual interactions. The specification includes multiple frame types, such as UID, URL, TLM, and the secure Eddystone-EID, allowing for flexible and interoperable beacon implementations.
Hardware manufacturers building BLE beacon devices, mobile application developers creating proximity-based experiences, and IoT engineers implementing location-aware systems.
Developers choose Eddystone because it is an open, cross-platform specification that ensures interoperability between beacons and apps, supports secure broadcasting with Eddystone-EID, and is designed for straightforward implementation on a wide range of BLE devices.
