Step by Step

Bluetooth

Bluetooth is an open standard for high-performance
technology and allows wireless communication be-
tween PCs, PDAs, mobile telephones, etc.
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 undergo a once-off discovery pro-
cedure.

for connection to a Bluetooth device

Discoverability

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

Linking

Linking is the process used by two Bluetooth-enabled
devices to "see" one another and to "recognize" that they
can exchange data. It is therefore used for checking the
access authorization of a Bluetooth device in a Blue-
tooth network. To do this, a 128 Bit linking key is creat-
ed for subsequent identification.
Linking is only performed the first time contact is
established between a Bluetooth device and your
OpenStage. If the Bluetooth device is successful-
ly linked, no further access authorization checks
are necessary. Instead, each subsequent check
uses the previously created connection key.
