MQTT blocks - Help for request blocks

[loucheman]

I need help with these blocks:

I understand all other blocks in the lib but not these.

I want to request who is online on a topic and wait for a restonse from all others...

Thank's!

Those blocks were made by the original author of the JavaScript code in the extension @xavierpi

I'll see if I can contact him off site and get him to come and explain them to you
