Open it by Right-Clicking, and then selecting ‘Run as administrator’ and clicking ‘Yes’ if User Account Control Dialog Box appears. Click on ‘Start’ button of Windows and search for- “cmd.exe” (Command Prompt). Change it to “Manual” (preferred) or “Automatic”.ģ. Select ‘Properties’ and ensure that the ‘Startup Type’ is NOT set to “Disabled”. On opening this, go to ‘Telnet’ and Right-Click on it. Click on ‘Start’ button of Windows and search for- “services.msc”.

How to create a TCP Server on Windows 7 or Windows Vista.ġ. If you use a WEP network or would like to change the way the Shield connects to the network, refer to the setWpa and setWep functions of the library for details on how to do this.

Change the value of IP address in the line String IP=”192.168.1.2″ and Port number in tcpclient.client_connect(IP,100) according to the IP and Port of the TCP server created.

key- 10 or 26 hexadecimal characters in case of WEP (example- 4A35535535), OR PassPhrase in case of WPA (example- DEXTERINDUSTRIES).

ind- Key Index with value ranging from 1 to 4, used only in WEP network.

ssid- SSID or Name of the WiFi Network you are connecting to.

In the setup function change the values of. In this file (TCPClient.ino) you must make the following changes before execution:ġ. This data is put into a String and is available for manipulation within the program code if and when required.

The Serial Monitor prints out the data that is received from the server.

After the connection has been established, you can enter data (characters,digits etc.) in the server and it will be transmitted to the client.

Open Serial Monitor to restart the program and create a TCP client.

After the server has been created, change the IP address and Port number of the server in the program and upload the code and library onto the Arduino with WiFi Shield.

This example is used with the library for Dexter Industries’ WiFi Shield for Arduino to create a TCP Client which connects to a server running on Port 100 on another machine, and reads data that the server sends.

The library and examples are compatible with Arduino version 1.0.1.

For use with the Dexter Industries’ WIFI Shield for Arduino.

Below we have outlined the examples and the details of the library.
