    BMP280 & Micropython issue

    Hi,

    I'm trying to use your BMP280 with a Raspberry Pi Pico & Micropython. I'm using this library : 
    https://github.com/dafvid/micropython-bmp280/blob/master/bmp280.py

    I get temp & pressure, but always the same values : 26.32 °C and 76078.56 Pa. Even when i put my finger on it to get a rise in temperature. Values stays the same.

    What am i doing wrong?

    Regards,

    Odo

    Hi Sir:

        Did you get BMP280 chip ID?

        Could you offer the whole operation sequences to tell us how you set BMP280 registers, include initialization and configuration and reading temperarture and pressure data?
