How to build chat application using MQTT

[chandan khatri]

Hi All,

I am totally new to mqtt and I am trying to do a POC for a chat application. My requirements are:

1. Users can exchange messages (1to1)

2. User can create a group and start exchanging messages with everyone.

For both the requirements I need to have users subscribe to a chat room. Not sure how I can do that, any help/pointers are highly appreciated.

Thanks,

CK

Hi Chandan,

Here you have wonderful slides by Bryan Boyd explaining
a concrete proposal about a set of messages, interactions and
subscription pattern for a chat application:

Harish,

Send the data on a certain topic and make sure that the receiving client is subscribed to that topic.

Good luck,

Thomas
