Arduino MQTT client with QoS1 and 2

Former Member
Former Member over 10 years ago

I got MQTT client for Arduino from "http://knolleary.net/arduino-client-for-mqtt/".But this seems to have only QoS0.

Do we have any upgraded version of Arduino MQTT client with QoS1 and 2.Is it possible to have QoS1 and 2 for MQTT publish and subscribe in Arduino?

    Hello Radhamani Ramadoss.

     

    In comment 99 at the same page you got it:

    These are not in the plan for this client as there is no reliable storage on the arduino, so we cannot provide proper QoS 1 or 2 semantics.

     

    This seems to me a reason to do not use QoS1 or QoS2 with arduino.

    Ok..I saw that..

    But the thing is,we prefer MQTT over HTTP because it provides guaranteed delivery with Qos1 and 2.When that is not possible with Arduino,then why we need to go for MQTT in Arduino?I am not sure what is the benefit of using MQTT with Arduino..

    Please let me know..
