118 Using Bluetooth
Using Bluetooth
Bluetooth is used for wireless communication, e.g. between PCs or tablets and
smartphones or headsets. Bluetooth can be used at a distance of up to 10 me-
ters. To exchange data between Bluetooth-enabled devices, the devices need
to undergo a once-off pairing procedure.
Discoverability
When first enabling a connection to a Bluetooth device, this function must be
switched on ïƒ page 138.
The OpenScape CP700/CP700X is recognizable by default for other Bluetooth
devices once you have opened the pairing menu.
The OpenScape CP700/CP700X discoverability feature is disabled on exiting
the pairing menu in order to prevent misuse.
Pairing
Pairing is the process used by two Bluetooth-enabled devices to "see" one an-
other and to "recognize" that they can exchange data. It is therefore used for
checking the access authorization of a Bluetooth device in a Bluetooth network.
A connection key is generated for later identification.
Pairing NFC-enabled devices
If your Bluetooth device has an NFC reader (Near Field Communication), it can
be paired very easily with your OpenScape CP700/CP700X (often smartphones
have this, but not headsets).
The NFC transmitter on the OpenScape CP700/CP700X is located in the top
right area of the display, to the left of the Forwarding key and below the "N" logo.
To pair the Bluetooth device, hover over this logo and follow the instructions (see
instructions for Bluetooth device).
A connection is established for devices that are already connected even if
the "Discoverable" function is deactivated.
Pairing is only performed the first time contact is established between a
Bluetooth device and your OpenScape CP700/CP700X. If the Bluetooth
device is successfully paired, no further access authorization checks are
necessary. Instead, each subsequent check uses the previously created
link key.
