Esp32 over mqtt


please, I need an explanation(in more details) for every code line in connecting esp32 to ubidots over mqtt


Greetings, this article may serve you as reference.

All the best


Thanks a lot for helping me
I need another help
I was wanting to send two variables (random data) to ubidots and I did ,
But there is a problem there is no data on ubidots appeared only on serial monitor?
this is the code
sketch_jul30a.ino (3.4 KB)

and this is the serial monitor screenshot


Please refer to this example to know how to send properly data through MQTT.

All the best


It doesn’t work with esp 32 ,so what now?


I have not noticed that you were using an esp32, the examples provided are intended for ESP8266, for ESP32 we have a reference example using microPython here.

You can find several resources that may serve you as reference at our help center too.

All the best.


I used this

as a reference it works only with one variable
if I added two or three variables it doesn’t work


Greetings, you will have to modify the payload built in the code to fit the structure below:


{"var-1": {"value": value-1}, "var-2": {"value": value-2}}

All the best
