The Example contains of OpenSSL server demo.
First you should configure the project by "make menuconfig":
Example Configuration ->
1. WIFI SSID: WIFI network to which your PC is also connected to.
2. WIFI Password: WIFI password
To configure the project, run `make menuconfig` (or `idf.py menuconfig` if using CMake build system).
* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../README.md) for more details.
* When using Make build system, set `Default serial port` under `Serial flasher config`.
IF you want to test the OpenSSL server demo:
1. compile the code and load the firmware
