You could open a TCP socket for connection and send messages. If you've downloaded the WICED SDK, /apps folder is where we have our sample apps. You could use the /apps/snip/tcp_client app or /apps/snip/tcp_server app. You'll need to change the AP SSID and password in /include/default_wifi_config_dct.h.
For directions on how to use the WICED IDE, look for the Quickstart Guide in the SDK/docs for WICED-QSG202-R.pdf.
