Re: [mosquitto-dev] Mosquitto disconnect when trying to send retain mess

[Ben Hardill <hardillb@xxxxxxxxx>]

Given the lack of any context in the original question, there was very little chance of any of the members of this list being able to give a useful answer (which probably explains the silence).

I can only assume the original poster is using the mosquitto client to connect to AWS, else this really wouldn't be the right place to ask.

This is the mosquitto-dev mailing list. I wonder why questions and issues regarding AWS IoT pop up here. The same thing happens in other projects.

AWS IoT has major limitations with regards to MQTT-3.1.1 functionality. A lot of key elements of MQTT are deliberately missing like Retained messages, QoS2, and persistent sessions. 

The MQTT 5 spec will make AWS IoT conforming again because the spec lists the missing features as optional.

In the future of MQTT we will see a lot of applications which will run with only one broker or will become a lot more complicated to configure and maintain.

Your views and opinions are highly appreciated
