    It analyzes the basic MQTT and MQTTS ports, uses an example for the Slovak public MQTT broker, which can be used for testing and getting acquainted with MQTT, shows in the programmatic implementation of the directive for the compiler - there is one source code for 3 different platforms.
    The second article deals with MQTTS (MQTT via TLS), contains practical commands of the OpenSSL tool, which can be used to obtain a Root CA certificate and SHA1 fingerprint of the MQTT broker certificate. This is desirable for the ESP8266 and ESP32 platforms and an encrypted implementation for MQTT. Refers to the PubSubClient library documentation.
    Both articles are aimed at the Github repository with software implementation for MQTT, MQTTS for Arduino + Ethernet, ESP8266, ESP32 platforms.
