quite new here so I need some help.

i have a tab5 and a bme688 env-pro.
I attached it to port a , it's recognized as 0x77.

I tried to write a block program, or even with python.

I can't get it working.

I always get a message that the i2c port is not initialized. I tried help from AI, but it says it doesn't work with tab5.

Can anybody help me?
thanks Alex
