MQTT how to get started

[alexll]

Hi there,

It's my first time using MQTT and I am a bit lost. I want to connect 2 LM and share group addresses between them, but after reading more and more posts about that, I have achieved nothing.

Steps that I followed:

- I have installed and configured MQTT broker app in one of my LMs;
- I have created a resident script and group addresses as showed here: https://forum.logicmachine.net/showthrea...6#pid10926 , pointing to localhost where the broker is, and to the broker IPs at the other;
- I have installed MQTT Explorer in my PC to monitoring everything;
- I'm stuck at this step, because I don't see anything at MQTT Explorer and I don't know what to do appart of changing group address values.

Can anybody help me or share a tutorial?

Thanks in advance!

Does the objects in your script exists? Any errors?
On the client LM with broker in use ip 127.0.0.1

Yes, I have created the same objects included in the script just to avoid any bug on my side (indeed I have tried with different data types as I don't know if that is relevant). 

The LM log shows "* arg: 1  * string: mqtt connect status * arg: 2  * bool: true * arg: 3  * number: 0 * arg: 4  * string: connection accepted * arg: 5  * number: 0 * arg: 6  * nil".

And yes, on the client with the installed broker I use the localhost IP.

Post your full script.

I do not know why, but, while I was taking the screenshots to post them for you, everything started to work flawlessly   .
Anyway, if anybody needs some help about this topic, just use this post.

Thank you admins!
