Description
Roaming
Link sensitivity low
medium
high
maximum
Sensitivity level at which the linked WEG reacts to disturbed radio
link and attempts to switch to a partner device with a potentially
strong signal.
The higher this setting, the earlier the WEG attempts to
change the link.
Select higher settings for scenarios in which fast roaming is
required.
Select low settings for quasi-static links with adverse
reception conditions.
Connect to name
scheme
Strategy for searching for new link partners
Assign name or partial name of potential partner
devices for evaluation of “Connect to name
scheme”!
The settings defined here are only effective (or of
significance) when the field
Device name
in the
section “Bluetooth”> “Connection” is not blank.
Name
•
The WEG will search for exactly
one device
.
•
The device checks whether the device name contains the
search string (see “Connection”).
•
The device establishes the link when this condition is
fulfilled; otherwise it begins a new search (inquiry).
This setting is suitable for scenarios in which normally only
the device to be linked is within range.
If other active
Bluetooth
®
devices are anticipated, use a
different procedure.
First name
•
The WEG searches for a
list of devices
in the
surrounding area.
•
The device checks each entry in the list to determine
whether the specific device name contains the search
string.
•
The WEG
establishes a link with the first device
to
which this applies.
As the order of the devices in the list of search results is
random, the chosen device may not be the device with
which the best link was able to be set up.
The initially detected device may be a device with low signal
strength, which will ultimately result in increased roaming.
Best name
•
The WEG searches for a
list of devices
in the
surrounding area.
•
The device
checks each entry in the list
to determine
whether the device name contains the search string.
•
The
signal strength is determined
for each discovered
device that meets this condition.
•
The WEG then establishes the link to an acceptable
device with which a link can be set up.
Of the three strategies, “Best name” requires the longest
time to set up a link, but does, however, usually provide the
best results.
