3.4 – Bluetooth® Pairing/Connect Modes
3.4.1– Manual Mode
This usage model is intended for applications where casual users of a public venue (sports bar, spa, stadium luxury box, fitness center)
have access to connect their devices to the audio system but headaches are minimized by eliminating automatic reconnect and pairing
history features.
In this mode, users connect their Bluetooth® audio enabled smart device by simply pressing the front panel “PAIR” button. The blue
Bluetooth® status LED will begin flashing to indicate that the DBU is now visible to other Bluetooth® devices and accepting pairings. This
pairing period lasts 60 seconds after which the status LED will stop flashing and turn off and the DBU will disable its Bluetooth® interface.
*Note:
The default Bluetooth friendly name visible to other devices is “
DBU-XXXXXX
” where “XXXXXX” is the DBU’s primary Ethernet MAC
address. This name can be customized by the installer using the unIFY Control Panel software.
If a successful pairing is made during the pairing period, the status LED will stop flashing and turn constantly on.
To disconnect a Bluetooth device from the DBU, press and hold the PAIR button for 5 seconds and then release it. The status LED will turn
off, and the connection will be reset. Another device may now be connected by repeating the pairing process.
3.4.2– Reconnect Mode
In this mode, the DBU maintains a pool of the last 8 paired devices and any previously paired device on that list will be permitted to reconnect
when in range of the DBU without requiring the front panel button to be pressed. The user simply selects the DBU friendly name on their
smart device.
Any new devices that are paired are added to the paired device list. If the list already full, a device from the list will be removed and the new
device added in its place.
3.4.3– Exclusive Mode
This mode is intended for restricted/personal use and works similarly in operation to reconnect mode. However, rather than allow any known
device from the pairing list to reconnect, only a specific device can be used with that particular DBU.
To setup a device as the exclusive device, set the DBU to “Exclusive” mode, clear the pairing list, and then pair the desired exclusive device
to the unit. The DBU makes a note of this device and from that point on, only that exclusive device will be allowed to reconnect to that
particular DBU when in range. As with the reconnect mode, reconnection is done without requiring the front panel button to be pressed by
simply selecting that particular DBU on their smart device.
Once the DBU has been associated with a device, both the front panel pair button and the remote “pair” command sent via the network are
disabled and will have no effect.
In order to attach a different device, either pairing list has to be cleared or the device mode needs to be changed.
*
Note:
In all modes once paired/connected, the Bluetooth® friendly name is able to be detected by other devices. However, while another
device may be able to pair and save to its Bluetooth® device list when in this state, breaking the connection of the currently active device
will not be possible.
