# wolfSSL Server Example


## VisualGDB

Open the VisualGDB Visual Studio Project file in the VisualGDB directory and click the "Start" button.
No wolfSSL setup is needed. You may need to adjust your specific COM port. The default is `COM20`.

## ESP-IDF Commandline

The Example contains a wolfSSL simple server.

1. `idf.py menuconfigure` to configure the project

    1-1. Example Connection Configuration ->
    
           WIFI SSID : your own WIFI, which is connected to the Internet.(default is "myssid")  
           WIFI Password : WIFI password, and default is "mypassword"

When you want to test the wolfSSL simple server demo

1. `idf.py -p <PORT> flash` to compile the code and load the firmware
2. `idf.py monitor` to see the context. The assigned IP address can be found in output message.
3. Once the server connects to the wifi, it is waiting for client request.  
    ("Waiting for a connection..." message will be displayed.)
   
4. You can use <wolfssl>/examples/client to test the server  
    e.g ./example/client/client -h xx.xx.xx

See the README.md file in the upper level 'examples' directory for more information about examples.
