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...

All,
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.
Regards
Pankaj
