BluEpyc BLE Smart KeyBeacon

Fully configurable Bluetooth® Low Energy Beacon with 3 action push buttons.

BluEpyc BLE KeyBeacon brings together the ability of the BLE to automatically transmit data and user’s voluntary activities: the three buttons are designed to transmit different types of information such as location based services or voluntary events (automation, access control, help, safety at work…). Suitable to communicate different user status/needs (notify presence, emergency alerts sending, area access, etc.). IoT & Active RFID application. Real Time Location System & Indoor Positioning System (zone method).


  • Through the on/off button it is possible to switch on and off the KeyBeacon; in deep-sleep state a considerable energy saving is achieved.
  • KeyBeacon is able to manage the different advertising modes: standard BLE, Apple iBeacon, Google Eddystone or custom advertising.
  • When KeyBeacon works, it transmits fully configurable watch-dog advertising; when one of the three action keys is pressed, 3 different special advertisings are transmitted (each fully configurable).
  • Protection rating suitable for outdoor use (IP 65). Replaceable battery. Battery life up to 2 years.
  • Responsive to specific application: the possibility of custom on-board applications (special firmware) allows to adapt the device to specific and custom uses.
  • Some application scenarios: vehicle & people access control (also stand alone), home & building management , safety (hospital, construction site, etc…), process automation, asset & facility management, smart city (parking, leisure & tourism, etc…)

The BluEpyc BLE Smart KeyBeacon firmware exposes configuration services via BLE OTA (Android App).

  • Power on/off button (Button 1): if pressed for more than 2 seconds, the status switches from deep-sleep to operational or vice versa.
  • Commissioning phase: when the KeyBeacon is switched on, it transmits a connectable advertising frame of duration, beacon interval and preset power useful for connection and customization of operating parameters (see table below); the advertising package contains, besides other information, also the version of the installed firmware.
  • Presence or Watch Dog: when the KeyBeacon works, it transmits (if enabled) advertising frames with customizable characteristics and format specified in the parameters (see table below).
  • Button 1 to 3 (Action): they can be configured to transmit advertising packages, called “Action”, with different format, timing, power and sending parameters (see table below).
Configurable parameters for advertsing packages – for both presence type ADV (Watch Dog) and Action type ADV (3 push buttons).
