|
* UIPEthernet TcpClient example.
|
|
*
|
|
* UIPEthernet is a TCP/IP stack that can be used with a enc28j60 based
|
|
* Ethernet-shield.
|
|
*
|
|
* UIPEthernet uses the fine uIP stack by Adam Dunkels <adam@sics.se>
|
|
*
|
|
* -----------------
|
|
*
|
|
* This TcpClient example gets its local ip-address via dhcp and sets
|
|
* up a tcp socket-connection to 192.168.0.1 port 5000 every 5 Seconds.
|
|
* After sending a message it waits for a response. After receiving the
|
|
* response the client disconnects and tries to reconnect after 5 seconds.
