Hello,
I use the following script to connect my CubeCell HTTC AB-02 module to TTN and to send fix values for temperature and humidity:

To read my BME 280 sensor and to submit real data I need some more libraries (Wire.h and BlueDot_BME280.h). But as soon as I include them - without further code - I get the following error messages:

What can I do to avoid this?
