tcp_client Example
=========

Configure
>>>>>>>>>
Please configure the ssid and password that need to be connected to WiFi in advance,in `main.c`.

 .. code-block:: c

    #define ROUTER_SSID "your ssid"
    #define ROUTER_PWD "your password"

Then configure the IP address and port number of the TCP server

 .. code-block:: c
   #define TCP_SERVER_IP "122.114.122.174"
   #define TCP_SERVER_PORT 7878

Compile and download
>>>>>>>>>

**Compile command**

make -j16

`-j8`is the number of cores in the system.

make flash p=/dev/ttyUSBx b=921600
`/dev/ttyUSBx`is the port number of the Ai-WB2 connection, usually ttyUSB0

Example Output
>>>>>>>>>

 
 .. code-block:: c
   
   (other log)...
   Server ip Address : 192.168.31.156 port:7878

   [      7383][INFO: main.c:  54] tcp_client_task:tcp client connect OK
   [      7387][INFO: main.c:  62] tcp client send OK



After the TCP client connects, it sends a "*hello tcp server*" to the server.The server sends a `close` message to close the connection.
