This example uses the TCP / IP socket API to implement a simple C / S structure of the program. Copy the executable program arm_client to the development board, pc_server copy to the PC, the development board and PC access network.

Configure IP of PC machine and run server program:

sudo ifconfig eth0 192.168.1.111
./pc_server
REC FROM: 192.168.1.222

Run client program on board:

ifconfig eth0 192.168.1.222
./arm_client 192.168.1.111
