I am doing the MQTT section of the ESP32 course. I pasted the code from the rntlab website. The only thing I changed is I’m using a BME280 so I included the Adafruit BME280 library and I’m using bme.readtemperature to get the temperature. I’m getting the following error in the serial monitor:
Connecting to MQTT…

Please help!

Hi.
In your sketch, you must delete all lines of code that refer to the DS18B20 sensor.
Additionally, you haven’t initialize the BME280 sensor. You need to do that.
Taking a look at this tutorial might help: https://randomnerdtutorials.com/esp32-mqtt-publish-bme280-arduino/
