Re: [paho-dev] Device: Auto Discovery

Hi Pankaj
there is nothing in MQTT natively to support advertising and directory services, but I know a number of people have implemented this using Avahi / mDNS type systems, with a service advertisement for not only the broker, but sometimes including the "kind of information" you'd find there on which topics.

But it is roll-your-own, with no agreed standardisation in the advertisement strings

Here are some helpful links...

I was looking for capability to automatically discover/monitor nearby devices connected to a Broker.


Does MQTT natively supports this ? What are some of those constructs that I can use to implement this.
