stm32l432kc with bme280 using i2c

I am a newbie, so please bear with me.

I have the stm32 and bme280 returning a hex value of 0x90, so I have to say they are communicating. I do not understand how to get the read/write sequences to work. Could someone please help me with the obtaining of data from the bme280?

Thanks in advance ..

Don't forget to have pull up resistor to VCC. Without them nothing will work. Look at this example ..it should works.
