MQTT

Publish device data to Qubitro using the lightweight MQTT protocol for real-time ingestion.

MQTT is a lightweight publish/subscribe messaging protocol designed for IoT applications.

Qubitro supports both MQTT v3.1.1 and MQTT v5.0, enabling secure and efficient data transmission from devices.
