Hello, I'm doing a project for college and I need to receive the temperature and humidity values. However, I'm getting an error message in the app that I can't fix.
The text you received is not what you expected.
It did not including ":", so your lista variable only contains one item, you can not get item 2.
How did your BT send the data?
upload your .ino file.
I see a semicolon (;) in your split.
Do you use a println() to transmit?
