Adafruit CC3000 Breakout/Shield TCP Chat Server
This is a simple chat server which allows clients to connect
with telnet and exchange messages. Anything sent by one
client will be written out to all connected clients.
See the CC3000 tutorial on Adafruit's learning system
for more information on setting up and using the
CC3000:
http://learn.adafruit.com/adafruit-cc3000-wifi
Requirements:
This sketch requires the Adafruit CC3000 library. You can
download the library from:
https://github.com/adafruit/Adafruit_CC3000_Library
For information on installing libraries in the Arduino IDE
see this page:
http://arduino.cc/en/Guide/Libraries
Usage:
Update the SSID and, if necessary, the CC3000 hardware pin
information below, then run the sketch and check the
output of the serial port. After connecting to the
wireless network successfully the sketch will output
the IP address of the server and start listening for
connections. Once listening for connections, connect
to the server from your computer using a telnet client
on port 23.
For example on Linux or Mac OSX, if your CC3000 has an
IP address 192.168.1.100 you would execute in a command
window:
telnet 192.168.1.100 23
Connect multiple clients and notice that whatever one client
sends will be echoed to all other clients. Press ctrl-] and
type quit at the prompt to close the telnet session.
On Windows you'll need to download a telnet client. PuTTY
is a good, free GUI client:
