WIFI_SCAN_LCD.C
WIFI_SCAN_LCD.C
illustrates the scan function of the Wi-Fi CompactFlash card to look
for access points or ad-hoc devices. This sample program does not require additonal con-
figuration of the Wi-Fi CompactFlash card, such as setting the IP number or SSID/channel
in order to function, since the Wi-Fi CompactFlash card does not actually join an 802.11b
network.
Before running this sample program, you will need to install an LCD/keypad module on
the Prototyping Board. Complete instructions are provided in the
User’s Manual for the
RabbitCore or PowerCore module you are using.
Once you have compiled and run the sample program, and the scan request has been
issued, the host RabbitCore or PowerCore module will read out the scan results and parse
the information. The scan results contain information for each device discovered. This
information includes the channel number, the MAC address, the signal strength of the
detected device, and the average noise level as seen by the device. It also includes the
SSID of the device.
The Dynamic C
STDIO
window will display
Scanning....Completed
, and will display
a list of access points/ad-hoc hosts in your vicinity as in the example shown below.
The same information will scroll down the LCD display on the LCD/keypad module.
