You do not need to configure the SSID of your network since that is done from the
access point names.
Now configure the access to the two access points.
Modify the access point names and keys to match your access points and network.
WIFIPINGYOU.C
Wi-Fi network.
This sample program uses some predefined macros. The first macro specifies the
default TCP/IP configuration from the Dynamic C
CONFIG.LIB
Use the next macro unchanged as long as you have only one RCM5400W RabbitCore
module. Otherwise use this macro unchanged for the first RabbitCore module.
Then change the macro to
program on the second RCM5400W RabbitCore module.
The next macros assign an SSID name and a channel number to the Wi-Fi network.
Finally, IP addresses are assigned to the RabbitCore modules.
As long as you have only one RCM5400W RabbitCore module, the Dynamic C
window will display the pings sent out by the module. You may set up a Wi-Fi enabled
laptop with the IP address in
If you have two RCM5400W RabbitCore modules, they will ping each other, and the
