Hi.
How do you get the altitude?

MQTT Topic: esp32/altitudine
Data: b”\xf0\xaa\xfc?\xac:\xfc?’\xe3\xc8\xa5\x807\xfc?|<\xfc?\x847\xfc?\x01″

Could you kindly help me decode the altitude field correctly so that I can insert it correctly into the MYSQL db.
Thanks for existing
Best regards

Hi.
You can see the code example in this tutorial. It subscribes to an MQTT topic to control the outputs: https://randomnerdtutorials.com/esp32-big-timer-node-red/
I hope this helps.

Sara

great tutorial. just wondering if you can add subscribes example using this mqtt asynchrony library to turn on led or something? if it’s possible.

thanks a lot guys

If it’s different can you please tell me what libraries I can use for my BME688 sensor.

Hi.
To use MQTT, you need an MQTT broker.
In this specific project, we’re using the MQTT mosquito broker installed on a Raspberry Pi.
You can check the following guides to learn how to get started with Raspberry Pi, MQTT, and how to install the MQTT mosquito broker on the Pi.
– Getting Started with Raspberry Pi
What is MQTT and How It Works
Install Mosquitto MQTT Broker on Raspberry Pi
If you don’t want to use a Raspberry Pi, you can install the broker on your computer, for example, or use a cloud broker.
I hope this helps.
Regards,
Sara

I’m about to start this project but I’m confused about the RaspberryPi would I have to use the board or how? Suggestions required.

by now I have to include
#include <AsyncMqttClient_Generic.hpp>
instead of
#include <AsyncMqttClient.h>
maybe they changed only the foilename
Yours Klaus
