プロジェクトの歴史

wolfSSL's changelog says wolfMQTT has existed since the project's beginning in 2015, and GitHub release metadata shows early public releases in November and December 2015. The GitHub repository was created in October 2015, matching the changelog's project-start chronology.

The library is part of the wolfSSL product family rather than an independent MQTT broker or application. Its README and product page describe it as an MQTT Client written in C for embedded use and built from the ground up to be multi-platform, space conscious, and extensible, with TLS supplied through wolfSSL.

採用の歴史

wolfMQTT's adoption follows the same embedded-security channel as wolfSSL: users who already rely on wolfSSL for TLS can add MQTT without bringing in a large runtime or a separate TLS stack. Its repository and releases show steady maintenance into the 2020s, with 2.0.0 released in March 2026.

A notable protocol transition was MQTT 5.0 support. wolfSSL's 2019 post noted that wolfMQTT, originally based on MQTT 3.1.1, also supported MQTT v5.0 after the OASIS standardization work, bringing features such as scalability improvements, better error reporting, capability discovery patterns, user properties, and support for small clients.

使われ方

Users embed wolfMQTT into firmware, gateways, RTOS applications, and C programs that need to publish or subscribe to broker topics. The examples include a general MQTT client, firmware update examples, and WebSocket broker tests, making the package useful both as a library dependency and as a reference implementation for constrained MQTT clients.

パッケージ好きにとっての重要性

The package matters because it is an MQTT client in the same packaging and licensing orbit as wolfSSL. For embedded package maintainers, that means a small C MQTT stack whose TLS story is deliberately aligned with the wolfSSL library already used for HTTPS, DTLS, and device-security work.
