WiFiNINA_SSL_Test.ino

/****************************************************************************************************************************
  WiFiNINA_SSL_Test.ino

  This example creates a client object that connects and transfers
  data using always SSL.

  It is compatible with the methods normally related to plain
  connections, like client.connect(host, port).

  Based on and modified from WiFiNINA library https://www.arduino.cc/en/Reference/WiFiNINA
  to support nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, etc. boards besides Nano-33 IoT, MKRWIFI1010, MKRVIDOR400, etc.
