MQTT-C
A portable MQTT v3.1.1 client library written in ANSI C for embedded systems and PCs.
What is MQTT-C?
MQTT-C is an open-source MQTT client library written in ANSI C that implements the MQTT v3.1.1 protocol. It provides a portable solution for connecting embedded systems and PCs to MQTT brokers, enabling lightweight publisher-subscriber messaging in IoT and networking applications. The library addresses the need for a small, thread-safe MQTT client that can run on resource-constrained devices.
Embedded systems developers and C programmers working on IoT projects, microcontrollers, or applications requiring MQTT communication in constrained environments.
Developers choose MQTT-C for its minimal footprint, ANSI C compatibility, and transparent Platform Abstraction Layer that simplifies porting. It offers a fully thread-safe design while maintaining efficiency for single-threaded systems, making it uniquely suited for embedded development.
