Bluetooth

Bluetooth is an open standard for high-performance technology and allows wire-
less communication between PCs, PDAs, and mobile telephones.
In contrast to infrared connections, Bluetooth does not require a visual contact
for communication purposes and can be used over distances of up to 10 meters.
To exchange data between Bluetooth-enabled devices, the devices need to un-
dergo a once-off discovery procedure.

Discoverability

When first enabling a connection to a Bluetooth device, this function must be
switched on
Page 233.
The OpenStage is discoverable for other Bluetooth devices by default.
To prevent unauthorised access, we recommend deactivating discoverability
once you have enabled the connection to a new Bluetooth device.
A connection is established for devices that are already connected even if
the "Discoverable" function is deactivated.

Pairing

Pairing is the process used by two Bluetooth-enabled devices to "see" one an-
other and to "recognise" that they can exchange data. It is therefore used for
checking the access authorisation of a Bluetooth device in a Bluetooth network.
To do this, a 128 bit link key is created for subsequent identification.
Pairing is only performed the first time contact is established between a
Bluetooth device and your OpenStage. If the Bluetooth device is success-
fully paired, no further access authorisation checks are necessary. In-
stead, each subsequent check uses the previously created connection
key.
