The Sparkplug specification was developed to help definehow best to get started using MQTT in a mission-critical, real-time application.
The MQTT protocol consists of three core components or mechanisms: Publisher, Broker and Subscriber.
Gambit has focused on adding these capabilities to its MQTT simulator to ensure this growing test area is also thoroughly covered.
For example, MQTT allows a sensor or a drive to pull information from the product and send it to the cloud.
The standard protocols itsupports for providing device connectivity are MQTT, CoAP and HTTP and supports both cloud and on-premises deployments.
MQTT's publish/subscribe model allows smart sensors to publish only new data for the devices configured to receive it.
It also acts as a gateway for collecting data from ground equipment andtransferring the data to cloud applications via MQTT publish/subscribe.
