Please provide some example code using the Tiny_GSM library to connect to a cloud MQTT broker on 8883. Example in the library will not connect to a private xxxxx.s1.eu.hivemq.cloud 8883 but connects to broker.hivemq.com 1883 without issue. // MQTT details const char* broker = "broker...

I'm thinking I can take that same scheme and set up similar event handlers in Ground Station's existing MQTT code in order to constantly transmit the same stats to a broker. I'd probably just make a simple JSON blob per hardware type and it would publish that blob to a per-device cl...

However, MQTT Quality-of-Service policies do not support timeliness requirements, which is common in IIoT. The literature reports several research works that address this limitation, but they are limited in scope (e.g., improvements in the broker’s internal operation, control of the publisher’...
After receiving publisher messages, the broker verifies its subscriber list to determine who is related to this topic and then forwards the messages to whomever is interested. After subscribers get the messages, they process them depending on their subscriptions’ relevance. 3.2. MQTT Security The MQ...
