Nice video and this is exactly what I was searching for from last 2 weeks

I really love your MQTT series, straight and clear.

Great vid! I actually have a question for you - I was wondering if it is possible for the app client to disconnect automatically the moment the app is closed. I'm not talking about closing a screen, but closing the actual app before reopening it. I found out that if I close the app entirely, even deleting it off my phone, the connection is still preserved, and I wish to change that.

thx but i think you must read the state of led when you launch your application in your smartphone because the led can be turned off and in your application seemes that it is turned on because pbs can happened in connexion to the internet ...
so i think that in your pg of nodemcu you must publish the state of led every 10"

Tengo un problema con el codigo de App inventor. Por alguna razon, cuando me conecto al topico para recibir los datos, despues de siete segundos, se desconecta el broker. Si no me conecto al topico, la conexión se mantiene, pero apenas empiezo a recibir datos, despues de siete segundos falla. Estoy enviando los datos cada 4 segundos, e hice la prueba cambiando el tiempo y pasa lo mismo. Gracias

[branko]

You are great and thank you for the video, but you should work much slower, this way we go back to every second of the video a million times to see what you pressed, and it is very tiring and frustrating.
