NL240 Wireless Network Link Interface
8.1 Wi-Fi Connection
8.1.1 Join an Existing Network
In this configuration, the device will scan for available networks and attempt to
join the network (infrastructure or ad hoc) specified by the
SSID
setting.
•
Connect to the NL240 in
DevConfig
(see Section
7
,
Configuring the
NL240
(p. 13)
).
•
Click on the
Wi-Fi
tab.
•
Set Configuration to
Join an Existing Network
.
•
Press the
Browse
button next to the
SSID
field to see a list of the available
networks in the area. Select the network you wish to connect to and click
OK
. If the
SSID
field is left blank, the device will attempt to join the
strongest unsecured network it finds.
•
If this is a secured network, enter the password in the
Password
field.
•
Under
Advanced
, set the
TX Power Level
and
Lower Power
mode.
(Note that these settings can often be left at their default values. See
Section
6.5
,
Power
(p. 12)
.)
•
Click
Apply
to save your changes.
If for some reason the device cannot join the desired network (for
example, out of range or incorrect parameters), it will go to a low-
power state and periodically retry to join the network
approximately once every minute. If the device has successfully
joined a network and then detects a loss of connectivity with the
network, it will begin periodically searching for the network at
approximately the one-minute interval.
8.1.2 Create an Ad hoc Network
In this configuration, the device will be the creator of an ad hoc network. An
ad hoc network created by the module supports up to 4 joinees.
Please remember when joining an ad hoc network with Windows
or iOS, it can take some time to successfully join the network.
•
Connect to the NL240 in
DevConfig
(see Section
7
,
Configuring the
NL240
(p. 13)
).
•
Click on the
Wi-Fi
tab.
•
Depending on whether or not you want your Ad hoc network to be
encrypted, set Configuration to
Create an Open Ad hoc Network
or
Create an Ad hoc Network with WEP Security
.
