CoAP is an IoT protocol that supports communication between low-consumption, low-power devices, which often run on constrained networks. For these reasons, CoAP is designed to be very concise and uses the UDP protocol for data transmission, allowing it to be well-adapted to constrained network environments. …

Introduction: Native MQTT Session Persistence Support The MQTT protocol standard states that the broker must store messages from offline clients. In previous versions, the open-source version of EMQX used memory-based session storage, while the enterprise version further provides an external database storage solution for data persistence. This memory-based, non-persistent session storage is the optimal solution based…

MQTT is an OASIS standard messaging protocol for the Internet of Things (IoT). It is designed as an extremely lightweight publish/subscribe messaging transport that is ideal for connecting remote devices with a small code footprint and minimal network bandwidth. …

Google made its decision to shut down Cloud IoT Core Service on August 16, 2023, leaving one year for its users to migrate from their service to an alternative one. The public announcement first appeared at the top of its IoT Core web page, followed by emails to its customers…

In the latest version 5.0, EMQX made a breakthrough by relaying MQTT message over QUIC protocol. QUIC (RFC 9000) is the underlying transport protocol of the next-generation Internet protocol HTTP/3, which provides connectivity for the modern mobile Internet with less connection overhead and message latency compared to TCP/TLS protocols. Based…

Keep Alive in MQTT protocol Why we Need Keep Alive The MQTT protocol is hosted on top of the TCP protocol, which is connection-oriented, and provides a stable and orderly flow of bytes between two connected parties. However, in some cases, TCP can have half-connection problems. A half-connection is a connection that has been disconnected or not established on one…

Recently, MQTT X, the cross-platform desktop client for MQTT 5.0, was released in version 1.8.0. MQTT X is designed to connect to MQTT brokers such as EMQX. It makes it easy and quick to create multiple simultaneous online MQTT client connections and test the connection, publishing, and subscription functions of…

EMQX Cloud, a fully managed MQTT cloud service, can provide users with reliable real-time IoT data movement, processing, and integration, helping to accelerate the development of IoT platforms and applications. In EMQX Cloud, the “Data Integration” module, optimized and upgraded based on the original high-performance built-in rule engine, provides a…
