It would be so good if you make video about mqtt in react-native.

Why i can send the message in the publisher, but i can not receive the message in the subscriber. Before i had put the same topic in the topic box and subscribed it.

Hi Sir and thank you for your nice work here.

I tried your cli-project and I am stuck at the problem that my Mosquitto broker requires user an password to authorise access.
Where and how would one include those parameters or arguments?

Just a dummy question, Can I publish and getting Subscribe at the same time? I want apply to my arduino, so i can active sensors and showing up into an angular app, that can modify them too. Thanks!
