Using the Optional Modules
Features Implemented
The WiFi module supports several transport configurations. The configuration can be
changed by having the application program send the appropriate commands to the WiFi
module over its UART interface.
Š
TCP client only
Š
TCP server and TCP client
Š
UDP client
Š
HTTP client
Note
The sample application does not support the module’s Secure Mode which
forces the module to only receive packets only from an IP address that
matches the stored host IP.
Default configuration is “TCP server and TCP client”. In this mode xPress behaves as
both TCP server and TCP client.
To change the mode, access point information, Server IP details, etc, it is necessary to
modify the configuration settings in the code (
app_demo\conf\conf_wifly.h
) and
recompile the application.
Also edit WIFLY_CONFIG_FILE with an appropriate new filename If any configuration
settings are modified.
Š
config filename format: "
config_mmddyyyyhhmm
"
This should start with
config_
and remaining part would be any new string.
C A U T I O N !

If the configuration filename in the application program is not changed,
any setting changes made at the same time will be ignored.
Following table provides the features supported and their configuration details.
