Bluetooth - in general

Bluetooth is a wireless technology for communicating over short distances (15m) between two devices. The devices can communicate with each other after they are paired and the communication is secure.

Functionality

Bluetooth identification is based on the unique code of the end device. Communication between the 2N IP Intercom (or 2N Access Unit) and the smartphone is secure and based on the principle of public and private keys, which are exchanged between the devices during pairing (the RSA 1028 asymmetric encryption mechanism and AES-128 symmetric encryption are used). 

Requirements

• 2N OS Firmware version 2.44 or later.
• IP Style, IP Verso 2.0/IP Verso/LTE Verso/Access unit 2.0/Access unit M.
• My2N App version 3.1.3 for Android or later/3.1.1 for iOS or later
• Bluetooth enabled on the phone
• Location Services Enabled (iOS)

How to set up a connection between the My2N App and the 2N Device (offline pairing)

• First, you must open the 2N device configuration web interface in the Hardware -> Extenders -> Bluetooth Module section. The default mode here is "in-app".  "On device" or "via motion detection" can also be selected. It is also possible to change the signal range here (5 options):
  • 1 Shortest range 
  • 2 
  • 3 
  • 4 
  • 5 Longest range 

• The default signal range is 0 - 2m (shortest range), which is the best option in terms of safety, as the Bluetooth reader will only communicate with a mobile phone in the immediate vicinity. The value can be changed depending on the need and desired functionality. It is important to keep in mind that each mobile phone may have a slightly different Bluetooth antenna sensitivity, which means that the distance of detectable signal may vary between phone types. The effective signal range depends on these parameters:
  • Transmitter signal output power
  • Receiver sensitivity
  • Physical obstacles in the signal path
  • Antenna parameters

You will then be able to open the door in the app by clicking on the door icon after successful pairing.

• The second step is to install the My2N App from the Apple Store or Google Play on the phone that will be used for access.
• The next step is to generate a pairing code on the 2N device side in the Directory -> Users section for the user who will have access via Bluetooth. 

• It is necessary to fill in the user name and then open the WaveKey section. Then click on the Bluetooth symbol and a matching code will be generated. This code must then be entered into the phone.

The default code validity is 1 hour - you must pair the phone with the 2N device until the code expires. 

• For pairing it is necessary to be close to the 2N device (1-2 meters).
• On the My2N app, go to the "home" screen. click on the + symbol and choose the option "Pairing PIN".

• Enter the PIN generated in the 2N device and click on the button "next".

• Click on the button "Start pairing" when you are close to the 2N device.

• Next screen will appear saying "paired successfully". Click on "OK" to confirm.

How to open the door (in app mode) using the My2N App 

• If the My2N application is already paired with the 2N device, it is necessary to be in the vicinity of the intercom/access unit.
• Open the My2N app, on the "home" screen, you should see all paired 2N devices with mobile phone.
• All you need to do is to click on the unlock button of the  device on which you want to open the door.

• If the user is allowed to enter, the door is opened and signalled in the application.
