Subject: [OASIS Issue Tracker] (MQTT-271) Describing small device limitations, aka "the Arduino problem"


    [ https://issues.oasis-open.org/browse/MQTT-271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=60874#comment-60874 ] 

Ed Briggs commented on MQTT-271:
--------------------------------

Thanks Ian, I agree. On point 4, I was saying what you said - transport behavior is outside the scope of MQTT.
Cheers
Ed

>             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
>          Issue Type: Improvement
>          Components: futures
>    Affects Versions: 3.1.1
>         Environment: Very small device implementations.

> Small devices, like the original Arduino, may have very limited resource, like 16k of RAM, or less.  For such devices, limiting the storage used by MQTT is very important.  
> They may not even be able to process a message of 30k, for instance, at all.  If it were sent at QoS 1 or 2, it has to be read in before subsequent messages are received.  
> At the moment, it is a server admin task, or application design task, to make sure that messages bigger than a device can handle are not sent to it.
