MQTT applications
MQTT (Message Queuing Telemetry Transport) is an ISO standard (ISO/IEC 20922) publish-subscribe
based light-weight messaging protocol for use on top of the TCP/IP protocol. It is designed for
connections with remote locations. The publish-subscribe messaging pattern requires a message
broker. The broker is responsible for distributing messages to interested clients based on the topic
of a message.
The Universal Gateway MQTT Interface is provides a bi-directional secure communication between
the broker end the gateway. This solution allows that applications can access to the gateway through
the internet.
The Figure 4 shows the Universal Gateway in a MQTT based solution.

The MQTT Client interface is transparent for the IQRF network that means the MQTT message
payloads contains the IQRF packet payloads in both directions (see 2.2.1
Example
)
The Universal Gateway MQTT Client Interface is fully compatible with
Amazon AWS IoT
or can use
open source brokers such as
Mosquitto
. To setup Universal Gateway to AWS IoT see
