246 Part III — More Complex Interfacing

Configuring Wi-Fi
If you want the WiMicro to join your network, you need to configure that too. In the follow-
ing example, the network is called todbot and has no security. From the setup menu, press 4,
then Enter, and then do this:
Enable WLAN (Y) ?
Topology 0=Infrastructure, 1=AdHoc (1) ? 0
Network name (SSID) (LTRX_IBSS) ? todbot
Security 0=none, 1=WEP, 2=WPA (0) ? 0
Data rate, Only : 0=1, 1=2, 2=5.5, 3=11 Mbps or
Up to: 4=2, 5=5.5, 6=11 Mbps (6) ?
Enable power management (N) ?

Configuring IP Address
Finally, to make it easier to find the WiMicro in the future, assign it an unused static IP
address on your wireless network. In this example, the unused address is 192.168.0.90.
From the setup menu, press 0, then Enter, and then do this:
IP Address : (000) 192.(000) 168.(000) 0.(000) 90
Set Gateway IP Address (N) ?
Netmask: Number of Bits for Host Part (0=default) (0)
Change telnet config password (N) ?

Saving the Configuration
With those three sets of changes made, it’s time to save the configuration. Press 9 and Enter,
and the WiMicro saves the configuration and resets itself to load the new settings. You’ll find
yourself disconnected from the LTRX_IBSS ad-hoc network. Connect to your wireless net-
work as usual, and you should be able to ping and telnet to the IP address you assigned the
WiMicro.

If you ever lose the WiMicro through a configuration mishap, you can reinitialize it to factory
defaults by holding down the reset button for seven seconds.
