Remote Connection

Technical Requirements

  • In order to allow ticket validation at different entry points, multiple devices can be connected using the multi-peer feature.
  • A single device acts as "master" by sharing its database with other devices which operate as "clients".
    • The connection will be established using Bluetooth and also WLAN if the devices are part of the same network.
    • The range and quality of the wireless connection depends on the environmental conditions and the individual configuration of the infrastructure being used.
    • A maximum of 7 clients can join one master.
    • Each client can only be attached to one master at a time.
    • The app must be installed an all participating devices and remain opened on both the master and the client to keep the connection active.

Configuration

  • The remote connection can be configured in the app's settings (see section "Settings").
  • The user chooses whether his device should operate as master or client.
  • The client uses the "Join" button to signal that it is ready to connect to a master.
    • The client can detach itself later if it does not wish to be reconnected automatically to this particular master anymore.
  • The master can add clients if they are visible and ready to join.
    • The client must confirm the procedure once when the master tries to establish a connection for the first time.
    • The master can remove joined clients if they should not be able to connect automatically anymore or if one of the available spots is supposed to be assigned to another client.

Functionality

  • When scanning a ticket on a client device, it will send the identification number (validation ID) to its master and request the ticket's status and details.
    • A client may also maintain a local database with its own events and tickets. However, these will not be considered as long as the remote connection remains enabled in the app's settings.
  • The master itself can also be used for ticket validation, but must stay in the reception area of its clients or the network.
    • If the connection is interrupted, an attempt will be made to automatically re-establish the connection as soon as the master or client comes back into range or becomes visible again.
  • While the connection to the master is active, the client will show the mode switch in the upper right corner in greenish color. If the connection has been lost, the switch is displayed in a reddish color.
