MQTT messaging protocol for IoT devices

Packet Tracer 7.1 improves IoT objects communication by introducing an inovative MQTT messaging capability. MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. This lightweight protocol for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. It is also an ideal messaging protocol for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers

MQTT has been an OASIS Standard since 15 October 2014.

The following sample shows an example of MQTT messages available in Packet Tracer 7.1 . MQTT clients subscribe to MQTT message queues hosted by a MQTT broker. Those two functions are available in Packet Tracer SBC-PT IoT module
