MQTT

MQTT is a lightweight, publish-subscribe network protocol that transports messages between two devices. The protocol runs over TCP/IP. It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.

Engiby has developed an MQTT library for Saia PCD® systems that allows you to publish PCD data and subscribe to defined topics. Other MQTT client, who subscribe to a topic in which you publish data, will receive what you publish. On the other way, if you subscribe to some topics you will receive data published by other MQTT clients in those topics.

Restrictions:
The library complies with the MQTT standard 3.1.1. (The standard 5.0 is not supported)
Only the Quality Of Service = 0 is implemented.
It is not allowed to use wildcards in the topics you subscribe to.
No secure link is supported by the PCD. (Only the username and password is supported)

Please contact Engiby for any request.
