Project Description

BluEpyc BLE Sensor Beacon Wake-up

Ultra-low power & fully configurable multi-function Sensor Beacon Wake-up. Sensors: LF 3D wake sensor, push button allarm , accelerometer, free fall, accurate position detection.

  • Special BluEpyc Sensor Beacon Wake-up (attached to person/item) usually in deep-sleep (battery life up to 4/5 years).
  • BluEpyc Beacon Activator generates an accurate “Wake-up area” (encoded LF field) of the Sensor Beacon Wake-Up. Activation area (3D bubble): 0.6-3.5 mtr. radius.
  • When the BluEpyc Sensor Beacon Wake-up enters the activation zone (accuracy 5/10 cm.), it transmits an Advertising with the code of the Beacon Activator that woke it up.
  • RFID mobile device C4050 Chainway by RFID Global
  • RFID mobile device C6000 Chainway by RFID Global
  • Beacon Activator Wake-Up System Function
  • BluEpyc Beacon Activator Wake-up Security System
  • Beacon Activator Wake-up Stand-Alone for safety

The new BluEpyc Beacon Activator Wake-up System is an evolutionary step aimed to improve the capability of Bluetooth in the indoor localization of people and assets.

Highlight

  • Special BluEpyc Sensor Beacon Wake-up (attached to person/item) usually in deep-sleep, is switched on by the BluEpyc Beacon Activator (accuracy 5/15 cm).
  • On board: Wake-Up LF, accelerometer, temperature, push button. Status LEDs (bi-color).
  • Multifunction Sensor Beacon Advertising: Presence (Watch Dog), Wake-up (with Area Code), Action/Allarm (push button), accelerometer (transmission on movement or free fall). All the functions can be activated and fully customized separately.
  • Responsive to specific application: custom on-board applications (special firmware) allows to adapt the device to specific and custom uses.
  • Protection rating suitable for outdoor use. Replaceable battery CR2032 3V Li; life up to 5 years (depending on use).
  • IoT & Active RFID application. Real Time Location System (zone method). Location Based Services.
  • Some application scenarios: Location Based Services, safety of warehouse operators, production management and traceability, precision access control, application in the health sector, etc…

The BluEpyc BLE Sensor Beacon Wake-up firmware exposes configuration services via BLE OTA (Android App).

  • Power on/off button: if pressed for more than 2 seconds, the status switches from deep-sleep to operational or vice versa.
  • Commissioning phase: when the Beacon 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 Beacon works, it transmits (if enabled) advertising frames with customizable characteristics and format specified in the parameters (see table below).
  • Button (Action): can be configured to transmit advertising packages, called “Action”, with different format, timing, power and sending parameters (see table below).
Configurable parameters for both presence type ADV (Watch Dog) and Action (push button)

Parameter Options / Range
Advertising status Active or inactive
Advertising Type Standard, Apple iBeacon, Google Eddystone UID/URL, Custom
Connettibile ADV Yes or Not
Frame interval From 100 ms to 100 min. (only presence type)
Frame Number From 1 to 65535
Beacon interval From 100 ms to 10000 ms (10 secs)
ADV Power From -10 dBm to +8 dBm

If activated, the BluEpyc Beacon Wake-up transmits advertising packages following specific events: Beacon Wake-up on movement

  • When the Beacon acceleration exceeds a certain configurable threshold, a ‘Movement’ type of Advertising packet is sent, containing the acceleration data on 3 axes (X, Y, Z).
  • The threshold sensitivity can be set on a scale from 1 to 10 (1 = high sensitivity)

Beacon ADV on Free Fall

  • When the Beacon is in free fall, the ‘Free Fall’ type advertising package is transmitted, containing acceleration data on 3 axes (X, Y, Z).
  • The activation sensitivity can be configured on a scale of values from 1 to 10 (1 = high sensitivity)
When the BluEpyc Beacon Wake-up enters the electromagnetic field produced by the Beacon Activator, an advertising package in BluEpyc format is generated containing the following information:

  • Current ID Beacon Activator: contains the identification code (0-4095) of the Beacon Activator in whose monitoring area the Beacon Wake-up has entered and activated
  • Previous Beacon Activator ID: contains the identification code (0-4095) of the Beacon Activator in which area has previously entered the Beacon Wake-up, if any, otherwise this field contains the value “0”
  • Counter: contains a packet counter, designed to prevent the host from processing redundant data
  • Beacon Wake-up Data: This 11-byte field is fully user-configurable and can be used to send additional information in the Wake-up package.

For the configuration of the Wake-up the standard parameters are provided among which:

  • Activating/deactivating Wake-up
  • Packages sent Connectable/Non-connectable
  • Number of packages to send
  • Transmitting Power & Beacon Interval
Special parameters related to the functional behavior of the Beacon in Wake-up mode:

  • Valid Time: validity time for sending new advertising packages (0 – 65535 sec.)
  • Mode: Preemptive/non Preemptive (refer to the table below)
  • Out Time: time spent outside the area (0 – 65535 sec.)

Valid Time Mode

Mode of Operation

Disabled Beacon broadcasts advertising every time it enters a Beacon Activator field.
Enabled/Non-Preemptive Beacon transmits advertising when it enters a Beacon Activator field and simultaneously activates the Valid Time count. As long as the Valid Time has not expired, the Beacon does NOT broadcast new Wake-up advertising packages whether it remains in the current Beacon Activator field or enters a new Beacon Activator field.
Enabled/Pre-emptive Beacon transmits advertising when it enters a Beacon Activator field and simultaneously activates the Valid Time count. If the Beacon remains in the current Beacon Activator field, it will NOT send new advertising packages until the Valid Time has expired. If the Beacon enters a new Beacon Activator field, regardless of the Valid Time (expired/not expired), it sends advertising packs for the new Beacon Activator field. If the Beacon leaves the current Beacon Activator field and re-enters the current Beacon Activator field, the advertising packet is broadcast:

  • if Valid Time has expired or
  • if Valid Time has NOT expired, but the Beacon has remained outside the current Beacon Activator field for a time greater than or equal to out time
