9. For
Wi-Fi Radio
, select the appropriate Wi-Fi radio.
10. (Optional) Set parameters that allow you to filter what devices appear in the output log:
a. Click to expand
Output log filtering
.
b. For
Minimum RSSI level to report
, type the minimum RSSI signal strength that a device
must have to be logged by the Wi-Fi scanner. This allows more distant devices to be
filtered out of the report.
The minimum allowed value is
-200
, and the maxium is
0
. The default is
-200
.
c. (Optional) For
File of blocklisted OUIs or MAC addresses
, specify the path and filename
to a file that contains a list of Organizationally Unique Identifiers (OUIs) and/or MAC
addresses that should be excluded from the output log. The OUI is the first three bits of
the MAC address. The file should take the format of one MAC address or OUI per line.
For example, the following example file,
/etc/config/scripts/blocklist.txt
, will blocklist all
devices with the OUI of 00.00.00, and also blocklist the three listed MAC addresses:
00:00:00
11:09:44:61:41:62
D0:40:FA:03:3A:92
3E:0F:20:CF:82:40
See
for information about uploading a file to the LR54 device's
filesystem.
d. For
Wi-Fi device type to report
, select either
Access points
,
Clients
, or
All
. The default is
All
.
e. (Optional) Configure the device to automatically determine what Wi-Fi signal transmitters
are stationary, and to exclude stationary devices from the output log:
i. Click to expand
Static transmitter filtering
.
ii. Click
Enable
.
iii. For
Observation period
, type the amount of time to observe devices before
determining if they are stationary.
Allowed values are any number of hours, minutes, or seconds, and take the format
number
{
h|m|s
}.
For example, to set
Observation period
to ten minutes, enter
10m
or
600s
.
The minimum allowed value is one second, and the maximum is one hour. The default
is 15 minutes.
iv. For
Maximum allowed RSSI variance
, type the maximum allowed variance of the
RSSI signal strength. Devices whose RSSI over the observation period varies more
than the maximum allowed variance will be considered to be mobile.
v. For
Minimum percentage of observation period
, type the percentage of times that a
device must be observed during the observation period. Devices that are observed
less that the minimum number will be considered to be mobile.
Allowed values are 1 to 100. The default is 50, meaning that a device must appear at
least half of the time during the observation period in order to be considered
stationary.
