PubNub has enhanced its support for the MQTT protocol within its Data Stream Network to facilitate efficient and reliable connectivity for low-powered embedded devices, particularly in the context of the Internet of Things (IoT). MQTT, a publish/subscribe protocol originally developed by IBM, is well-suited for environments where resources are limited, such as those involving smart devices. PubNub's integration allows users to leverage existing MQTT infrastructure while benefiting from PubNub's scalability and real-time capabilities. To use MQTT with PubNub, users must sign up for a PubNub account to obtain unique publish and subscribe keys, which are essential for establishing connections and creating channels. Although the current support is limited to QoS level 0 and does not include topic wildcards, future updates are expected to address these limitations. PubNub's integration with MQTT aims to provide a seamless experience by allowing messages to be published across both PubNub and MQTT, thereby enhancing the flexibility and reach of IoT applications.
