2.3 Bluetooth: Pairing and Connecting, Defined

We often encounter customers who use the terms pairing and
connecting, believing them to mean the same thing. They are different,
and it's important to understand why.
1) When you first get a VarioUltra, it is neither paired or connected with
your devices.
2) Pairing is the process of introducing VarioUltra to your device
(smartphone, computer, etc.), and vice versa. This process is
required so that Bluetooth devices grant permission to each other to
connect.
3) Connecting is the process of taking two paired devices – e.g.
VarioUltra and your smartphone – and connecting over Bluetooth. It is
not possible to connect via Bluetooth with a device that has not been
paired.
Once pairing and connected have been done, you can think of it this
way:
1) When VarioUltra and your device are in range, they are paired and
connected.
2) If you take your device and walk away from VarioUltra, the connection
will eventually brake. In this situation, you are paired but not
connected.
3) When your device is once again in range of VarioUltra, it should
connect again automatically, so long as VarioUltra is switched on.

2.4 Is Bluetooth Off or On?

Bluetooth is off by default when switching on VarioUltra for the first time.
Additionally, if you switch off VarioUltra or put it in to suspend mode,
Bluetooth will be turned off.
With VarioUltra v1.33 and older versions of VarioUltra software,
switching off the device results in Bluetooth being switched off. Bluetooth
remains off until you switch it on again, which can be achieved in Braille
Display mode by simply selecting a Bluetooth channel (S2+B4, for
example), and in Braille Notetaker mode by checking the box in Settings
> Bluetooth.
