#MQTT V5.0 OASIS Standard published

21 Mar 2019

OASIS is pleased to announce the publication of its newest OASIS Standard, approved by the members on March 7th:

MQTT Version 5.0
OASIS Standard
07 March 2019

MQTT is a client/server publish/subscribe messaging transport protocol. It is lightweight, open, simple, and designed to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.

The protocol runs over TCP/IP, or over other network protocols that provide ordered, lossless, bi-directional connections.

The prose specifications and related files are available here:
