MQTT

MQTT Version 5.0 Protocol

OASIS Standard publish/subscribe messaging protocol for IoT and M2M communication. MQTT v5.0 defines the wire format and behavior of CONNECT, PUBLISH, SUBSCRIBE, UNSUBSCRIBE, PINGREQ, DISCONNECT and other control packets exchanged between MQTT clients and brokers over TCP (typically 1883, or 8883 with TLS) or WebSockets. Authentication is broker-specific and may include username/password, X.509 client certificates, or OAuth/JWT enhanced authentication.
