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 in a defined topic with the Quality Of Service = 0. The library complies with the MQTT standard 3.1.1. Any other client who subscribed to the same topic will receive a copie of the message. The subscription to a topic and the reception of other client's messages will be implemented in a futur version.

Please contact Engiby for any request.
