/****************************************************************************************************************************
  ESP32-Client.ino
  For ESP32.

  Based on and modified from Gil Maimon's ArduinoWebsockets library https://github.com/gilmaimon/ArduinoWebsockets
  to support STM32F/L/H/G/WB/MP1, nRF52 and SAMD21/SAMD51 boards besides ESP8266 and ESP32


  The library provides simple and easy interface for websockets (Client and Server).

  Esp32 Websockets Client

  This sketch:
        1. Connects to a WiFi network
        2. Connects to a Websockets server
        3. Sends the websockets server a message ("Hello to Server from ......")
        4. Prints all incoming messages while the connection is open

  Hardware:
        For this sketch you only need an ESP32 board.
