Passkey
_________ Assign a passkey (max. 16 characters, no spaces,
Standard passkey: “0000”)
The passkey (commonly referred to as the “
Bluetooth
®
PIN”)
is used as the base value for calculating the actual link keys
(“Link Keys”).
The link keys, in turn, enable the use of secure authentication
and encrypted data transfer.

7.3.5.3 Bluetooth: Roaming
The WEG supports roaming between several other WEGs or PAN-compliant
Bluetooth
®
network access points. The
Bluetooth
®
device name of the other
device is used in this process to identify as many link partners as possible.
If a device name has been given under “Bluetooth > Connection > Device name”
and if a configuration has been saved using
[Set Roaming]
, the device will
always attempt to establish a link based on the specified strategy (“Connect to
name scheme”).
In addition to restart and loss of link, the trigger input can also be used to initiate a
new link setup. If a rising flank is recognized at the trigger input (see Section
“Connections”), the WEG will terminate the existing wireless link and will set up
a new link in line with the specified strategy.
