libmqtt's Introduction

MQTT line protocol implementation library

MQTT is a lightweight pubsub messaging protocol. It's much simpler than complex messaging protocols like AMQP but nevertheless may be quite handy for Internet of Things and many other tasks. Among other things, it supports nice WebSocket encapsulation which may be later added to this driver, too.

This library unbundles the cl-mqtt line protocol implementation from the process management aspects of that library. (https://github.com/ivan4th/cl-mqtt)

Example code:

(defun test-it (host port)
  (let ((conn (mqtt:connect host :port port)))
    (bt:make-thread #'(lambda ()
                        (let ((subscription (mqtt:subscribe conn "/a/#")))
                          (loop until (null (let ((message (mqtt:receive subscription)))
                                              (when (plusp (length message))
                                                (format t "~%RECEIVED: ~s~%"
                                                        (babel:octets-to-string
                                                         (mqtt:mqtt-message-payload message)
                                                         :encoding :utf-8)))))))))
    (mqtt:publish conn "/a/b" "whatever1")
    (mqtt:publish conn "/a/b" "whatever2")
    (mqtt:publish conn "/a/b" "")
    (mqtt:disconnect conn)))
