Edge MQTT

Overview

The Edge MQTT application is able to run in two modes:

  • as a standalone MQTT message broker at the edge, providing a lightweight approach to publish/subscribe messaging between devices and applications, and
  • in bridging enabled, forwarding edge MQTT messages to an external MQTT broker.

Bridging mode brings resiliency to MQTT at the edge, storing messages when the external broker becomes unavailable (for example, because of configuration errors, or site network outage), and automatically transmitting the buffered messages when the broker is accessible again.
