MQTT protocol
Live Objects supports the MQTT protocol to enable bi-directional (publish/subscribe) communications between devices or applications and the platform.
MQTT must be used with encryption (TLS layer). It is possible to use MQTT without encryption in "device" mode but we strongly recommend a secured connection. MQTT can be used with or without encryption (TLS layer).
Live Objects also supports MQTT over secure WebSocket.
The Live Objects MQTT interface offers multiples "modes":
-
mode "device": dedicated only to device connection use-cases, based on simple JSON messages,
-
mode "connector": dedicated to application that will act as cloud gateway and transfer device status and data from devices toward Live Objects
-
mode "application": useful for your business application to retrieve data or event from Live Objects.
