Bluetooth - in general

It's a technology for wireless communication between two devices for a short distance in the 2,4GHz radiofrequency band.

Functions

It is possible to use Bluetooth technology instead of RFID cards. This identification is provided by a code which is unique to the end-devices equipped with this technology ie; most modern smartphones. Communication is secure and based on public and private keys that are exchanged (we use RSA-1028 asymmetric encryption and AES-128 symmetric encryption).

Variants of HW installation

There are three installation possibilities for the 2N® Access Unit equipped with a Bluetooth module :

  1. Stand-alone Access Unit  factory equipped internally  with a BT module - Access Unit Bluetooth  (916013)
  2. Stand-alone Access Unit factory equipped with combo BT + RFID module - Access Unit  13,56MHz & Bluetooth (9160335 or 9160335-S)
  3. Access Units (916009, 916010, 916019) expanded by external BT module (9155046 or combo modules 9155082, 9155084) connected to the internal bus

Requirements

2N® IP Access Unit with firmware version 2.25 or higher

2N® Mobile Key app version 1.0.4 for iOS or version 2.0 for Android

    In case that 2N® IP Access Units are managed using 2N® Access Commander, you do not need to pair with each door device.

    When the app on a mobile device detects a new 2N Bluetooth-equipped device, it will connect to it and check if the user is authorized for access.

    Icon

    In case that 2N® IP Acces Units are not managed using 2N® Access Commander, an administrator can export a Bluetooth pairing settings backup and distribute it (import) to other door units. This procedure is described in the following article:

    Bluetooth, Administration - How to configure Bluetooth settings directly in device and how to distribute configuration ( export / import ) between devices

    When the app on a mobile device detects a new 2N Bluetooth-equipped device, it will connect to it and check if the user is authorized for access.

    Icon

    In case that 2N® IP Access Units are not managed using 2N® Access Commander and Administrator cannot distribute settings using export / import feature, a user needs to pair his mobile device with the app with each door unit.
