6.2.3 Configuration Information
6.2.3.1 Network/Wi-Fi Configuration
Any device placed on an Ethernet-based Internet Protocol (IP) network must have its own
IP address. IP addresses are 32-bit numbers that uniquely identify a device. Besides the IP
address, we also need a netmask, which is a 32-bit number that tells the TCP/IP stack what
part of the IP address identifies the local network the device lives on.
The sample programs configure the RCM4400W modules with a default
macro from the
allows specific IP address, netmask, gateway, and Wi-Fi parameters to be set at compile
time. Change the network settings to configure your RCM4400W module with your own
Ethernet settings only if that is necessary to run the sample programs; you will likely need
to change some of the Wi-Fi settings.
• Network Parameters
There are similar macros defined for the various Wi-Fi settings as explained in Section 6.3.1.
The Wi-Fi configurations are contained within
